Neutrophilic dermatoses—a group of inflammatory cutaneous conditions—include acute febrile neutrophilic dermatosis (Sweet syndrome), pyoderma gangrenosum, and neutrophilic dermatosis of the dorsal hands. Histopathology shows a dense dermal infiltrate of mature neutrophils. In 2005, the histiocytoid subtype of Sweet syndrome was introduced with histopathologic findings of a dermal infiltrate composed of immature myeloid cells that resemble histiocytes in appearance but stain strongly with neutrophil markers on immunohistochemistry.¹ We present a case of histiocytoid pyoderma gangrenosum with histopathology that showed a dense dermal histiocytoid infiltrate with strong positivity for neutrophil markers on immunohistochemistry.

An 85-year-old man was seen by dermatology in the inpatient setting for a new-onset painful abdominal wound. He had a medical history of myelodysplastic syndrome (MDS), high-grade invasive papillary urothelial carcinoma of the bladder, and a recent diagnosis of low-grade invasive ascending colon adenocarcinoma. Ten days prior he underwent a right colectomy without intraoperative complications that was followed by septic shock. Workup with urinalysis and urine culture showed minimal pyuria with Pseudomonas aeruginosa. Additional studies, including blood cultures, abdominal wound cultures, computed tomography of the abdomen and pelvis, renal ultrasound, and chest radiographs, were unremarkable and showed no signs of surgical site infection, intra-abdominal or pelvic abscess formation, or pulmonary embolism. Broad-spectrum antibiotics—vancomycin and piperacillin-tazobactam—were started. Persistent fever (T_max of 102.3 °F [39.1 °C]) and leukocytosis (45.3×10⁹/L [4.2–10×10⁹/L]) despite antibiotic therapy, increasing pressor requirements, and progressive painful erythema and purulence at the abdominal surgical site led to debridement of the wound by the general surgery team on day 9 following the initial surgery due to suspected necrotizing infection. Within 24 hours, dermatology was consulted for continued rapid expansion of the wound. Physical examination of the abdomen revealed a large, well-demarcated, pink-red, indurated, ulcerated plaque with clear to purulent exudate and superficial erosions with violaceous undermined borders extending centrifugally from the abdominal surgical incision line (Figure 1A). Two punch biopsies sent for histopathologic evaluation and tissue culture showed dermal edema with a dense histiocytic infiltrate with nodular foci and admixed mature neutrophils to a lesser degree (Figure 2). Special staining was negative for bacteria, fungi, and mycobacteria. Immunohistochemistry revealed positive staining of the dermal inflammatory infiltrate with CD68, myeloperoxidase, and lysozyme, as well as negative staining with CD34 (Figure 3). These findings were suggestive of a histiocytoid neutrophilic dermatosis such as Sweet syndrome or pyoderma gangrenosum. Due to the morphology of the solitary lesion and the abrupt exacerbation shortly after surgical intervention, the patient was diagnosed with histiocytoid pyoderma gangrenosum. At the same time, the patient’s septic shock was treated with intravenous hydrocortisone (100 mg 3 times daily) for 2 days and also achieved a prompt response in the cutaneous symptoms (Figure 1B).

Sweet syndrome and pyoderma gangrenosum are considered distinct neutrophilic dermatoses that rarely coexist but share several clinical and histopathologic features, which can become a diagnostic challenge.² Both conditions can manifest clinically as abrupt-onset, tender, erythematous papules; vesiculopustular lesions; or bullae with ulcerative changes. They also exhibit pathergy; present with systemic symptoms such as pyrexia, malaise, and joint pain; are associated with underlying systemic conditions such as infections and/or malignancy; demonstrate a dense neutrophilic infiltrate in the dermis on histopathology; and respond promptly to systemic corticosteroids.^2-6 Bullous Sweet syndrome, which can present as vesicles, pustules, or bullae that progress to superficial ulcerations, may represent a variant of neutrophilic dermatosis characterized by features seen in both Sweet syndrome and pyoderma gangrenosum, suggesting that these 2 conditions may be on a spectrum.⁵Clinical features such as erythema with a blue, gray, or purple hue; undermined and ragged borders; and healing of skin lesions with atrophic or cribriform scarring may favor pyoderma gangrenosum, whereas a dull red or plum color and resolution of lesions without scarring may support the diagnosis of Sweet syndrome.⁷ Although both conditions can exhibit pathergy secondary to minor skin trauma such as venipuncture and biopsies,^2,3,5,8 Sweet syndrome rarely has been described to develop after surgery in a patient without a known history of the condition.⁹ In contrast, postsurgical pyoderma gangrenosum has been well described as secondary to the pathergy phenomenon.⁵

Our patient was favored to have pyoderma gangrenosum given the solitary lesion, its abrupt development after surgery, and the morphology of the lesion that exhibited a large violaceous to red ulcerative and exudative plaque with undermined borders with atrophic scarring. In patients with skin disease that cannot be distinguished with certainty as either Sweet syndrome or pyoderma gangrenosum, it is essential to recognize that, as neutrophilic dermatoses, both conditions can be managed with either the first-line treatment option of high-dose systemic steroids or one of the shared alternative first-line or second-line steroid-sparing treatments, such as dapsone and cyclosporine.²

Although the exact pathogenesis of pyoderma gangrenosum remains to be fully understood, paraneoplastic pyoderma gangrenosum is a frequently described phenomenon.^10,11 Our patient’s history of multiple malignancies, both solid and hematologic, supports the likelihood of malignancy-induced pyoderma gangrenosum; however, given his history of MDS, several other conditions were ruled out prior to making the diagnosis of pyoderma gangrenosum.

Classically, neutrophilic dermatoses such as pyoderma gangrenosum have a dense dermal neutrophilic infiltrate. Concurrent myeloproliferative disorders can alter the maturation of leukocytes, subsequently leading to an atypical appearance of the inflammatory cells on histopathology. Further, in the setting of myeloproliferative disorders, conditions such as leukemia cutis, in which there can be a cutaneous infiltrate of immature or mature myeloid or lymphocytic cells, must be considered. To ensure our patient’s abdominal skin changes were not a cutaneous manifestation of hematologic malignancy, immunohistochemical staining with CD20 and CD3 was performed and showed only the rare presence of B and T lymphocytes, respectively. Staining with CD34 for lymphocytic and myeloid progenitor cells was negative in the dermal infiltrate and further reduced the likelihood of leukemia cutis. Alternatively, patients can have aleukemic cutaneous myeloid sarcoma or leukemia cutis without an underlying hematologic condition or with latent peripheral blood or bone marrow myeloproliferative disorder, but our patient’s history of MDS eliminated this possibility.¹² After exclusion of cutaneous infiltration by malignant leukocytes, our patient was diagnosed with histiocytoid neutrophilic dermatosis.

A variety of skin problems can occur in musicians due to the repetitive movements of playing instruments.^1,2 Musicians’ nails are continuously exposed to the mechanical forces and chemical substances characteristic of their instruments.³ Occupational nail alterations in musicians caused by repetitive physical trauma, allergic contact dermatitis, and/or infection may lead to disability and compromise their professional career.³

We conducted a systematic review of the literature on the clinical features of musical instrument–related nail alterations to optimize the management and prevention of these conditions.

Methods

We conducted a systematic review of PubMed, Scopus, and Google Scholar databases for eligible publications on instrument-related nail alterations in musicians using the search terms musicians with nail, onychopathy, and Raynaud. No time or language criteria were applied. Reviews, editorials, and articles not related to the topic were excluded. Bibliographies/reference lists were checked to find any additional relevant publications. Relevant articles in English and French were screened by 2 independent reviewers (A.G. and N.L.), and the following data were extracted for qualitative synthesis: sex, age, musical instrument, clinical features, number of years practicing the instrument, laboratory investigations, and disease course.

Results

The literature search yielded 11 publications. Sixteen additional articles were identified by other methods (ie, references, related publications). Overall, 3 full-text articles described general nail alterations but did not describe the clinical data, and 11 publications were editorials, commentaries, reviews, or not relevant. Thirteen contributions fulfilled the inclusion criteria and were eligible for qualitative synthesis. The flow diagram illustrates the screening process (Figure 1).

Twenty-three patients were included. The instruments identified were divided into 2 groups: string instruments (ie, guitar, violin, harp) and percussion instruments (ie, drums, piano, slap bass). Nail alterations were clinically expressed as: (1) modifications of the nail surface; (2) nail bed, soft-tissue, and bone abnormalities; and (3) periungual tissue and distal pulp disorders. All cases are summarized in the Table.^4-16 Three articles described occupational Raynaud phenomenon.^12-14

Comment

Modifications of the Nail Surface—Onychodystrophy, such as deformity or discoloration of the nail plate, was described in 6 patients among a cohort of 295 musicians and an additional 6 patients among 199 musicians with induced skin lesions. This condition was most common in string instrument players and pianists due to injury and irritation.^4,5

One patient, who had been a professional violist for 27 years, presented with lamellar onychoschizia, which corresponds to a horizontal splitting of the nail toward its distal portion (Figure 2). The 3 fingernails of the dominant hand were involved with a V-shaped incision of the distal margin of the nail due to the repetitive friction of the nails with the strings.⁶

Striations of the nail plate were reported in a guitarist who played for 10 years.⁷ Physical examination revealed linear transverse ridges alternating with depressions on the central aspect of the nail plate of the right thumbnail, as the patient was right-handed. This condition, attributed to sustained pressure on the string applied by the thumb, also has been called habit tic deformity.⁷

Nail Bed, Soft-Tissue, and Bone Lesions—Purpura (or hemorrhage) of the nail bed was associated with a percussion instrument (ie, piano) in 1 patient, affecting the second, third, and fourth fingernails of the right hand.⁸ Especially when performing ascending glissando passages, the pianist applies pressure that may damage the finger and cause fingernail purpura. This condition improved after the patient stopping practicing glissandi.⁸

Conclusion

Healthy nails are essential for playing a musical instrument. This review highlights the occurrence of fingertip callosities, paronychia, onycholysis, and subungual hemorrhages among musicians who play instruments. Additionally, the transmission of string-vibratory movements can produce microvascular damage and occupational Raynaud phenomenon in some musicians. These occupational nail disorders are underrecognized and may be underdiagnosed. Thus, musicians and clinicians must be aware of these alterations to adopt preventive measures and to provide adequate treatment.

The Comparison

A Traction alopecia in a Hispanic woman who wears her hair in a tight bun.

B Traction alopecia in a Black adolescent girl who wears her hair in tight hairstyles.

Traction alopecia (TA) is a common type of alopecia that ultimately can result in permanent hair loss. It often is caused or worsened by repetitive and prolonged hairstyling practices such as tight ponytails, braids, or locs, or use of wigs or weaves.¹ Use of headwear, as in certain religious or ethnic groups, also can be contributory.² Individuals participating in or training for occupations involving military service or ballet are at risk for TA due to hairstyling-specific policies. Early stages of TA are reversible with proper treatment and avoidance of exacerbating factors, emphasizing the importance of prompt recognition.³

Epidemiology

Data on the true prevalence of TA are lacking. It can occur in individuals of any race or any hair type. However, it is most common in women of African descent, affecting approximately one-third of this population.⁴ Other commonly affected groups include ballerinas and active-duty service members due to tight ponytails and buns, as well as the Sikh population due to the use of turbans as a part of their religious practice.^2,5,6

Traction alopecia also impacts children, particularly those of African descent. A 2007 study of schoolchildren in South Africa determined that more than 17% of young African girls had evidence of TA—even some as young as 6 years of age.⁷

Traction alopecia can be caused or exacerbated by the use of hair clips and bobby pins that aid holding styles in place.⁸

Hair shaft morphology may contribute to the risk for TA, with more tightly coiled hair types being more susceptible.⁸ Variables such as use of chemical relaxers also increase the risk for disease, especially when combined with high-tension styling methods such as braids.⁹

Key clinical features

Patients with TA clinically present with hair loss and breakage in areas with tension, most commonly the marginal areas of the scalp as well as the frontal hairline and temporal scalp. Hair loss can result in a “fringe sign,” in which a patient may have preservation of a thin line of hairs at the frontal aspect of the hairline with a band of hair loss behind.¹⁰ This presentation may be used to differentiate TA from other forms of alopecia, including frontal fibrosing alopecia and female pattern hair loss. When the hair loss is not marginal, it may mimic other forms of patchy hair loss including alopecia areata and trichotillomania. Other clinical findings in TA may include broken hairs, pustules, and follicular papules.¹⁰ Patients also may describe symptoms such as scalp tenderness with specific hairstyles or headaches,¹¹ or they may be completely asymptomatic.

Trichoscopy can be helpful in guiding diagnosis and treatment. Patients with TA often have perifollicular erythema and hair casts (cylindrical structures that encircle the proximal hair shafts) in the earlier stages of the disease, with eventual loss of follicular ostia in the later stages.^10,12 Hair casts also may indicate ongoing traction.¹² The flambeau sign—white tracks seen on trichoscopy in the direction the hair is pulled—resembles a lit torch.¹³

Early-stage TA can be reversed by avoiding hair tension. However, patients may not be amenable to this due to personal hairstyling preferences, job duties, or religious practices. Treatment with topical or intralesional steroids or even oral antibiotics such as doxycycline for its anti-inflammatory ability may result in regrowth of lost hair if the follicles are not permanently lost and exacerbating factors are avoided.^3,14 Both topical and oral minoxidil have been used with success, with minoxidil thought to increase hair density by extending the anagen (growth) phase of hair follicles.^3,15 Culturally sensitive patient counseling on the condition and potential exacerbating factors is critical.¹⁶

At later stages of the disease—after loss of follicular ostia has occurred—surgical interventions should be considered,¹⁷ such as hair transplantation, which can be successful but remains a technical challenge due to variability in hair shaft curvature.¹⁸ Additionally, the cost of the procedure can limit use, and some patients may not be optimal candidates due to the extent of their hair loss. Traction alopecia may not be the only hair loss condition present. Examining the scalp is important even if the chief area of concern is the marginal scalp.

Prevention, early identification, and treatment initiated in a timely fashion are crucial to prevent permanent hair loss. There are added societal and cultural pressures that impact hairstyle and hair care practices, especially for those with tightly coiled hair.¹⁹ Historically, tightly coiled hair has been unfairly viewed as “unprofessional,” “unkempt,” and a challenge to “manage” by some. Thus, heat, chemical relaxers, and tight hairstyles holding hair in one position have been used to straighten the hair permanently or temporarily or to keep it maintained in a style that did not necessitate excessive manipulation—often contributing to further tension on the hair.

Military service branches have evaluated and changed some hair-related policies to reflect the diverse hair types of military personnel.²⁰ The CROWN Act (www.thecrownact.com/about)—“Creating a Respectful and Open World for Natural Hair”—is a model law passed by 26 states that prohibits race-based hair discrimination, which is the denial of employment and educational opportunities because of hair texture. Although the law has not been passed in every state, it may help individuals with tightly coiled hair to embrace natural hairstyles. However, even hairstyles with one’s own natural curl pattern can contribute to tension and thus potential development of TA.

Traction alopecia (TA) is a common type of alopecia that ultimately can result in permanent hair loss. It often is caused or worsened by repetitive and prolonged hairstyling practices such as tight ponytails, braids, or locs, or use of wigs or weaves.¹ Use of headwear, as in certain religious or ethnic groups, also can be contributory.² Individuals participating in or training for occupations involving military service or ballet are at risk for TA due to hairstyling-specific policies. Early stages of TA are reversible with proper treatment and avoidance of exacerbating factors, emphasizing the importance of prompt recognition.³

Epidemiology

Data on the true prevalence of TA are lacking. It can occur in individuals of any race or any hair type. However, it is most common in women of African descent, affecting approximately one-third of this population.⁴ Other commonly affected groups include ballerinas and active-duty service members due to tight ponytails and buns, as well as the Sikh population due to the use of turbans as a part of their religious practice.^2,5,6

Traction alopecia also impacts children, particularly those of African descent. A 2007 study of schoolchildren in South Africa determined that more than 17% of young African girls had evidence of TA—even some as young as 6 years of age.⁷

Traction alopecia can be caused or exacerbated by the use of hair clips and bobby pins that aid holding styles in place.⁸

Hair shaft morphology may contribute to the risk for TA, with more tightly coiled hair types being more susceptible.⁸ Variables such as use of chemical relaxers also increase the risk for disease, especially when combined with high-tension styling methods such as braids.⁹

Key clinical features

Patients with TA clinically present with hair loss and breakage in areas with tension, most commonly the marginal areas of the scalp as well as the frontal hairline and temporal scalp. Hair loss can result in a “fringe sign,” in which a patient may have preservation of a thin line of hairs at the frontal aspect of the hairline with a band of hair loss behind.¹⁰ This presentation may be used to differentiate TA from other forms of alopecia, including frontal fibrosing alopecia and female pattern hair loss. When the hair loss is not marginal, it may mimic other forms of patchy hair loss including alopecia areata and trichotillomania. Other clinical findings in TA may include broken hairs, pustules, and follicular papules.¹⁰ Patients also may describe symptoms such as scalp tenderness with specific hairstyles or headaches,¹¹ or they may be completely asymptomatic.

Trichoscopy can be helpful in guiding diagnosis and treatment. Patients with TA often have perifollicular erythema and hair casts (cylindrical structures that encircle the proximal hair shafts) in the earlier stages of the disease, with eventual loss of follicular ostia in the later stages.^10,12 Hair casts also may indicate ongoing traction.¹² The flambeau sign—white tracks seen on trichoscopy in the direction the hair is pulled—resembles a lit torch.¹³

The Diagnosis: Folliculotropic Mycosis Fungoides

Folliculotropic mycosis fungoides (FMF) is a variant of mycosis fungoides (MF) characterized by folliculotropism and follicular-based lesions. The clinical manifestation of FMF can vary and includes patches, plaques, or tumors resembling nonfolliculotropic MF; acneform lesions including comedones and pustules; or areas of alopecia. Lesions commonly involve the head and neck but also can be seen on the trunk or extremities. Folliculotropic mycosis fungoides can be accompanied by pruritus or superimposed secondary infection.

Histologic features of FMF include follicular (perifollicular or intrafollicular) infiltration by atypical T cells showing cerebriform nuclei.¹ In early lesions, there may be only mild superficial perivascular inflammation without notable lymphocyte atypia, making diagnosis challenging. ^2,3 Mucinous degeneration of the follicles—termed follicular mucinosis—is a common histologic finding in FMF.^1,2 Follicular mucinosis is not exclusive to FMF; it can be primary/idiopathic or secondary to underlying inflammatory or neoplastic disorders such as FMF. On immunohistochemistry, FMF most commonly demonstrates a helper T cell phenotype that is positive for CD3 and CD4 and negative for CD8, with aberrant loss of CD7 and variably CD5, which is similar to classic MF. Occasionally, larger CD30+ cells also can be present in the dermis. T-cell gene rearrangement studies will demonstrate T-cell receptor clonality in most cases.²

Many large retrospective cohort studies have suggested that patients with FMF have a worse prognosis than classic MF, with a 5-year survival rate of 62% to 87% for early-stage FMF vs more than 90% for classic patchand plaque-stage MF.^4-7 However, a 2016 study suggested histologic evaluation may be able to further differentiate clinically identical cases into indolent and aggressive forms of FMF with considerably different outcomes based on the density of the perifollicular infiltrate.⁵ The presence of follicular mucinosis has no impact on prognosis compared to cases without follicular mucinosis.^1,2

Alopecia mucinosa is characterized by infiltrating, erythematous, scaling plaques localized to the head and neck.⁸ It is diagnosed clinically, and histopathology shows follicular mucinosis. The terms alopecia mucinosa and follicular mucinosis often are used interchangeably. Over the past few decades, 3 variants have been categorized: primary acute, primary chronic, and secondary. The primary acute form manifests in children and young adults as solitary lesions, which often resolve spontaneously. In contrast, the primary chronic form manifests in older adults as multiple disseminated lesions with a chronic relapsing course.^8,9 The secondary form can occur in the setting of other disorders, including lupus erythematosus, hypertrophic lichen planus, alopecia areata, and neoplasms such as MF or Hodgkin lymphoma.⁹ The histopathologic findings are similar for all types of alopecia mucinosa, with cystic pools of mucin deposition in the sebaceous glands and external root sheath of the follicles as well as associated inflammation composed of lymphocytes and eosinophils (Figure 1).^9,10 The inflammatory infiltrate rarely extends into the epidermis or upper portion of the hair follicle. Although histopathology alone cannot reliably distinguish between primary and secondary forms of alopecia mucinosa, MF (including follicular MF) or another underlying cutaneous T-cell lymphoma should be considered if inflammation extends into the upper dermis, epidermis, or follicles or is in a dense bandlike distribution.¹¹ On immunohistochemistry, lymphocytes should show positivity for CD3, CD4, and CD8. The CD4:CD8 ratio often is 1:1 in alopecia mucinosa, while in FMF it is approximately 3:1.10 CD7 commonly is negative but can be present in a small percentage of cases.¹² T-cell receptor gene rearrangement studies have detected clonality in both primary and secondary alopecia mucinosa and thus cannot be used alone to distinguish between the two.¹⁰ Given the overlap in histopathologic and immunohistochemical features of primary and secondary alopecia mucinosa, definitive diagnosis cannot be made with any single modality and should be based on correlating clinical presentation, histopathology, immunohistochemistry, and molecular analyses.

Inflammatory dermatoses including seborrheic dermatitis also are in the differential diagnosis for FMF. Seborrheic dermatitis is a common chronic inflammatory skin disorder affecting 1% to 3% of the general population. ¹³ Patients usually present with scaly and greasy plaques and papules localized to areas with increased sebaceous glands and high sebum production such as the face, scalp, and intertriginous regions. The distribution often is symmetrical, and the severity of disease can vary substantially.¹³ Sebopsoriasis is an entity with overlapping features of seborrheic dermatitis and psoriasis, including thicker, more erythematous plaques that are more elevated. Histopathology of seborrheic dermatitis reveals spongiotic inflammation in the epidermis characterized by rounding of the keratinocytes, widening of the intercellular spaces, and accumulation of intracellular edema, causing the formation of clear spaces in the epidermis (Figure 2). Focal parakeratosis, usually in the follicular ostia, and mounds of scaly crust often are present. ¹⁴ A periodic acid–Schiff stain should be performed to rule out infectious dermatophytes, which can show similar clinical and histologic features. More chronic cases of seborrheic dermatitis often can take on histologic features of psoriasis, namely epidermal hyperplasia with thinning over dermal papillae, though the hyperplasia in psoriasis is more regular.

Alopecia areata is an immune-mediated disorder characterized by nonscarring hair loss; it affects approximately 0.1% to 0.2% of the general population.¹⁵ The pathogenesis involves the premature transition of hair follicles in the anagen (growth) phase to the catagen ( nonproliferative/involution) and telogen (resting) phases, resulting in sudden hair shedding and decreased regrowth. Clinically, it is characterized by asymptomatic hair loss that occurs most frequently on the scalp and other areas of the head, including eyelashes, eyebrows, and facial hair, but also can occur on the extremities. There are several variants; the most common is patchy alopecia, which features smooth circular areas of hair loss that progress over several weeks. Some patients can progress to loss of all scalp hairs (alopecia totalis) or all hairs throughout the body (alopecia universalis). ¹⁵ Patients typically will have spontaneous regrowth of hair, with up to 50% of those with limited hair loss recovering within a year.¹⁶ The disease has a chronic/ relapsing course, and patients often will have multiple episodes of hair loss. Histopathologic features can vary depending on the stage of disease. In acute cases, a peribulbar lymphocytic infiltrate preferentially involving anagen-stage hair follicles is seen, with associated necrosis, edema, and pigment incontinence (Figure 3).¹⁶ In chronic alopecia areata, the inflammation may be less brisk, and follicular miniaturization often is seen. Additionally, increased proportions of catagen- or telogen-stage follicles are present.^16,17 On immunohistochemistry, lymphocytes express both CD4 and CD8, with a slightly increased CD4:CD8 ratio in active disease.¹⁸

Psoriatic alopecia describes hair loss that occurs in patients with psoriasis. Patients present with scaly, erythematous, psoriasiform plaques or patches, as well as decreased hair density, finer hairs, and increased dystrophic hair bulbs within the psoriatic plaques.¹⁹ It often is nonscarring and resolves with therapy, though scarring may occur with secondary infection. Psoriatic alopecia may occur in the setting of classic psoriasis and also may occur in psoriasiform drug eruptions, including those caused by tumor necrosis factor inhibitors.^20,21 Histologic features include atrophy of sebaceous glands, epidermal changes with hypogranulosis and psoriasiform hyperplasia, decreased hair follicle density, and neutrophils in the stratum spinosum (Figure 4). There often is associated perifollicular lymphocytic inflammation with small lymphocytes that do not have notable morphologic abnormalities.

Patients present with scaly, erythematous, psoriasiform plaques or patches, as well as decreased hair density, finer hairs, and increased dystrophic hair bulbs within the psoriatic plaques.¹⁹ It often is nonscarring and resolves with therapy, though scarring may occur with secondary infection. Psoriatic alopecia may occur in the setting of classic psoriasis and also may occur in psoriasiform drug eruptions, including those caused by tumor necrosis factor inhibitors.^20,21 Histologic features include atrophy of sebaceous glands, epidermal changes with hypogranulosis and psoriasiform hyperplasia, decreased hair follicle density, and neutrophils in the stratum spinosum (Figure 4). There often is associated perifollicular lymphocytic inflammation with small lymphocytes that do not have notable morphologic abnormalities.

The Diagnosis: Pigmented Nodular Basal Cell Carcinoma

Dermoscopy of our patient’s irregular dark brown papule revealed large blue clustered clods and radial lines converging to a central dot (middle quiz image). Histopathology revealed nests of basaloid cells with peripheral palisading, small horn pseudocysts, and deposits of melanin extending into the dermis (Figure). These findings were consistent with a diagnosis of pigmented nodular basal cell carcinoma (BCC).

Nodular BCC represents 60% to 80% of all BCC cases; pigmented BCC represents 6% of BCC cases.¹ Basal cell carcinomas frequently manifest as pearly papules with areas of pigment, surface telangiectases, and foci of ulceration. Dermoscopic features include fine arborizing vessels, blue-gray ovoid nests, spoke wheel–like structures, leaflike structures, and focal ulceration.¹ Histopathology shows well-defined dermal nodules comprising basaloid epithelial cells with peripheral palisading, mucinous stroma, focal melanin deposits, and surrounding clefting.² Arborizing vessels correspond to dilated vessels in the dermis.³ Blue-gray ovoid nests are wellcircumscribed ovoid or elongated structures that correspond histologically to well-defined large tumor nests with melanin aggregates invading the dermis. Spoke wheel–like structures are well-circumscribed radial projections connected to a pigmented central axis that correspond histologically to tumor nests near the epidermis and that appear as fingerlike projections with centrally located melanin deposits.³

The differential diagnosis of our patient’s lesion included nodular melanoma, lentigo maligna melanoma, deep penetrating nevus, and cellular blue nevus. Nodular melanoma is an invasive melanoma that lacks a radial growth phase. Dermoscopically, the more common features are a bluewhite veil, atypical vascular pattern, asymmetric pigmentation, atypical pigment network, and peripheral black globules.⁴ Histopathology reveals atypical melanocytes and architectural disorder.² Pigmented nodular BCC also can display dark globules on dermoscopy but typically has smaller and more arborizing blood vessels and does not have a pigmented network. Furthermore, BCC would not have atypical melanocytes on histopathology.^4,5

Dermoscopy of lentigo maligna melanoma displays hyperpigmented follicular openings, an annular-granular pattern, pigmented rhomboidal structures, and obliterated hair follicles.⁶ Histopathology demonstrates epidermal atrophy, increased pigmentation in basal keratinocytes, prominent solar elastosis, and an increased number of melanocytes that extend beyond the epidermis. ⁷ Pigmented nodular BCC can be distinguished from lentigo maligna melanoma dermoscopically by the presence of arborizing vessels, blue-gray ovoid nests, and lack of a pigment network.

Deep penetrating nevus is a darkly pigmented melanocytic lesion that infiltrates deeply into the reticular dermis.⁸ Specific dermoscopic features have not been well established; however, a uniformly dark blue or black pattern is common. Histologically, this type of nevus is symmetric and wedge shaped with a broad base extending to the deep dermis and subcutaneous fat.⁸ Melanocytes do not exhibit atypia or bizarre mitoses. Although pigmented nodular BCC can appear similar to deep penetrating nevus, histologically there will be atypical basaloid epithelial cells in BCC.

Blue nevi clinically appear as a smooth blue-gray lesion with a steel blue ground-glass pattern on dermoscopy. Histopathology shows spindle-shaped melanocytes in the dermis, which distinguishes this lesion from BCC.⁹

Consider pigmented BCC when a patient presents with a pigmented lesion. Dermoscopy can help appreciate a pigmented BCC by looking for features such as a spoke wheel– like pattern, blue ovoid nests, arborizing blood vessels, and lack of a pigment network. Because pigmented BCC constitutes a small fraction of all BCCs, it is important to be familiar with its presentation and dermoscopic features.

Although individuals with skin of color (SoC) are expected to become at least half of the US population by the year 2044, there remains a paucity of education and exposure to treatment of patients with SoC at many dermatology residency programs across the country.¹ One way to improve SoC education has been the formation of specialized clinics, centers, and programs. The first SoC center (SoCC) was established in 1999 at Mount Sinai–St. Luke’s Roosevelt in New York, New York²; since then, at least 13 additional formal SoCCs or SoC specialty clinics (SoCSCs) at US academic dermatology programs have been established.

Skin of color centers serve several important purposes: they improve dermatologic care in patients with SoC, increase research efforts focused on SoC dermatologic conditions, and educate dermatology resident and fellow trainees about SoC. Improving dermatologic care of patients with SoC in the United States is important in providing equitable health care and improving health disparities. Studies have shown that patient-physician racial and cultural concordance can positively impact patient care, increase patient trust and rapport, and improve patient-physician communication, and it can even influence patient decision-making to seek care.^3,4 Unfortunately, even though the US population continues to diversify, the racial/ethnic backgrounds of dermatologists do not parallel this trend; Hispanic and Black physicians comprise 18.9% and 13.6% of the general population, respectively, but represent only 4.2% and 3.0% of dermatologists, respectively.^5-7 This deficit is mirrored by resident and faculty representation, with Black and Latino representation ranging from 3% to 7%.^8-10

Many SoCC’s engage in research focused on dermatologic conditions affecting patients with SoC, which is vital to improving the dermatologic care in this underserved population. Despite increasing recognition of the importance of SoC research, there remains a paucity of clinical trials and research specifically focused on or demonstrating equitable representation of SoC.^11,12

The education and training of future dermatologists is another important area that can be improved by SoCCs. A 2008 study involving 63 chief residents showed that approximately half (52.4% [33/63]) of graduating dermatology residents reported receiving SoC-specific didactics, sessions, or lectures, and 30.2% (19/63) reported having a dedicated rotation where they gained specific experience treating patients with SoC.¹³ A later study in 2022 (N=125) found that 63.2% of graduating dermatology residents reported receiving SoC-specific didactics, sessions, or lectures, and only 11.2% reported having a dedicated rotation where they gained experience treating patients with SoC.¹⁴ These findings suggest that in the last 14 years, formal SoC education—specifically SoC clinical training—has not increased sufficiently.

We conducted a cross-sectional survey study to provide an in-depth analysis of SoCCs and SoCSCs in the United States, including their patient care focus, research, and program diversity.

Methods

We conducted an investigator-initiated, multicenter, cross-sectional survey study of all SoCCs in the United States and their respective academic residency programs. Fifteen formal SoCCs and/or SoCSCs were identified by dermatology program websites and an article by Tull et al² on the state of ethnic skin centers. All programs and centers identified were associated with a dermatology residency program accredited by the Accreditation Council for Graduate Medical Education.

A 42-item questionnaire was sent via email to the directors of these centers and clinics with the intent to collect descriptive information about each of the SoCCs, the diversity of the faculty and residents of the associated dermatology department, current research and funding, diversity and inclusion initiatives, and trainee education from March through April 2020. Data were analyzed using Excel and SPSS statistical software to obtain descriptive statistics including the mean value numeric trends across programs.

This study underwent expedited review and was approved by the University of Southern California (Los Angeles, California) institutional review board (IRB #HS-20-00113). Patient consent was not applicable, as no information was collected about patients.

Results

Fourteen directors from SoCCs/SoCSCs completed the questionnaire (93.3% response rate). Most centers were located in urban areas (12/14 [85.71%]), except for 2 in rural or suburban settings (Table). Most of the SoCCs/SoCSCs were located in the South (5/14 [35.71%]), followed by the Northeast (4/14 [28.57%]), West (3/14 [21.43%]), and Midwest (2/14 [14.29%])(Table). Six (42.86%) of the programs had a SoCSC, 3 (21.43%) had a formal SoCC, and 5 (35.71%) had both. Across all centers, the most common population seen and treated was Black/African American followed by Hispanic/Latino and Asian, respectively. The most commonly seen dermatologic conditions were acne, pigmentary disorders, alopecia, and atopic dermatitis (Figure). The most common cosmetic practice performed for patients with SoC was dermatosis papulosa nigra/seborrheic keratosis removal, followed by laser treatments, skin tag removal, chemical peels, and neuromodulator injections, respectively.

Faculty and Resident Demographics and Areas of Focus—The demographics and diversity of the dermatology faculty and residents at each individual institution also were assessed. The average number of full-time faculty at each institution was 19.4 (range, 2–48), while the average number of full-time faculty who identified as underrepresented in medicine (URiM) was 2.1 (range, 0–5). The average number of residents at each institution was 17.1 (range, 10–31), while the average number of URiM residents was 1.7 (range, 1–3).

Comment

As the number of SoCCs/SoCSCs in the United States continues to grow, it is important to highlight their programmatic, research, and educational accomplishments to show the benefits of such programs, including their ability to increase access to culturally competent and inclusive care for diverse patient populations. One study found that nearly 92% of patients in the United States seen by dermatologists are White.¹⁵ Although studies have shown that Hispanic/Latino and Black patients are less likely to seek care from a dermatologist,^16,17 there is no indication that these patients have a lesser need for such specialty care. Additionally, outcomes of common dermatologic conditions often are poorer in SoC populations.¹⁵ The dermatologists leading SoCCs/SoCSCs are actively working to reverse these trends, with Black and Hispanic/Latino patients representing the majority of their patients.

Faculty and Resident Demographics and Areas of Focus—Although there are increased diversity efforts in dermatology and the medical profession more broadly, there still is much work to be done. While individuals with SoC now comprise more than 35% of the US population, only 12% of dermatology residents and 6% of academic dermatology faculty identify as either Black or Hispanic/Latino.^5,8,10 These numbers are even more discouraging when considering other URiM racial groups such as Pacific Islander/Native Hawaiians or Native American/American Indians who represent 0% and 0.1% of dermatology faculty, respectively.^8,10 Academic programs with SoCCs/SoCSCs are working to create a space in which these discrepancies in representation can begin to be addressed. Compared to the national 6.8% rate of URiM faculty at academic institutions, those with SoCCs/SoCSCs report closer to 10% of faculty identifying as URiM.¹⁸ Moreover, almost all programs had faculty specialized in at least 1 condition that predominantly affects patients with SoC. This is of critical importance, as the conditions that most commonly affect SoC populations—such as CCCA, hidradenitis suppurativa, and cutaneous lupus—often are understudied, underfunded, underdiagnosed, and undertreated.^19-22

Faculty SoC Research—An important step in narrowing the knowledge gap and improving health care disparities in patients with SoC is to increase SoC research and/or to increase the representation of patients with SoC in research studies. In a 2021 study, a PubMed search of articles indexed for MEDLINE using the terms race/­ethnicity, dyschromia, atopic dermatitis, and acne was conducted to investigate publications pertaining to the top 3 most common chief concerns in patients with SoC. Only 1.6% of studies analyzed (N=74,941) had a specific focus on SoC.¹² A similar study found that among the top 5 ­dermatology-focused research journals, only 3.4% of all research (N=11,003) on the top 3 most common chief concerns in patients with SOC was conducted in patients with SoC.²³ Research efforts focused on dermatologic issues that affect patients with SoC are a priority at SoCCs/SoCSCs. In our study, all respondents indicated that they had at least 1 ongoing observational study; the most commonly studied conditions were CCCA, keloids/hypertrophic scarring, and atopic dermatitis, all of which are conditions that either occur in high frequency or primarily occur in SoC. Only 35.71% (5/14) of respondents had active clinical trials related to SoC, and only 21.43% (3/14) and 28.57% (4/14) had internal and external funding, respectively. Although research efforts are a priority at SoCCs/SoCSCs, our survey study highlights the continued paucity of formal clinical trials as well as funding for SoC-focused research. Improved research efforts for SoC must address these deficits in funding, academic support, and other resources.

It also is of great importance for institutions to provide support for trainees wanting to pursue SoC research. Encouragingly, more than half (57.14%) of SoCCs/SoCSCs have developed formal research opportunities for residents, and nearly 64.29% have formal opportunities for medical students. These efforts to provide early experiences in SoC research are especially impactful by cultivating interest in working with populations with SoC and hopefully inspiring future dermatologists to engage in further SoC research.

SoC Education and Diversity Initiatives—Although it is important to increase representation of URiM physicians in dermatology and to train more SoC specialists, it is imperative that all dermatologists feel comfortable recognizing and treating dermatologic conditions in patients of all skin tones and all racial/ethnic backgrounds; however, many studies suggest that residents not only lack formal didactics and education in SoC, but even more unsettling, they also lack confidence in treating SoC.^13,24 However, one study showed that this can be changed; Mhlaba et al²⁵ assessed a SoC curriculum for dermatology residents, and indeed all of the residents indicated that the curriculum improved their ability to treat SoC patients. This deficit in dermatology residency training is specifically addressed by SoCCs/SoCSCs. In our study, all respondents indicated that residents rotate through their centers. Moreover, our study found that most of the academic institutions with SoCCs/SoCSCs provide a SoC didactic curriculum for residents, and almost all of the programs invited SoC specialists to give guest lectures. This is in contrast to a 2022 study showing that 63.2% (N=125) of graduating dermatology residents reported receiving SoC-specific didactics, sessions, or lectures.¹⁴ These findings highlight the critical role that SoCCs/SoCSCs can provide in dermatology residency training.

Although SoCCs/SoCSCs have made considerable progress, there is still much room for improvement. Namely, only half of the respondents in our study indicated that their program has formally incorporated a SoC textbook into resident education (eTable 3). Representation of SoC in the textbooks that dermatology residents use is critically important because these images form the foundation of the morphologic aids of diagnosis. Numerous studies have analyzed popular dermatologic textbooks used by residency programs nationwide, finding the number of SoC images across dermatology textbooks ranging from 4% to 18%.^26,27 The use of standard dermatology textbooks is not enough to train residents to be competent in diagnosing and treating patients with SoC. There should be a concerted effort across the field of dermatology to encourage the development of a SoC educational curriculum at every academic dermatology program, including SoC textbooks, Kodachromes, and online/electronic resources.

Efforts to increase diversity in dermatology and dermatologic training should start in medical school preclinical curriculums and medical student rotations. Although our survey did not assess current medical student curricula, the benefits of academic institutions with SoCCs/SoCSCs are highlighted by the ability for both home and visiting medical students to rotate through the centers and gain early exposure to SoC dermatology. Most of the programs even provide scholarships and/or grants for URiM students to help fund their rotations, which is of critical importance considering the mounting data that the financial burden of visiting rotations disproportionately affects URiM students.²⁸

Study Limitations—Although we did an extensive search and believe to have correctly identified all 15 formal SoCCs/SoCSCs with a high response rate (93.3%), there are institutions that do not have formalized SoCCs/SoCSCs but are known to serve SoC populations. Likewise, there are private dermatology practices not associated with academic centers that have SoC specialists and positively contribute to SoC patient care, research, and education that were not included in this study. Additionally, the data for this study were collected in 2020 and analyzed in 2021, so it is possible that not all SoCCs, divisions, or clinics were included in this study, particularly if established after 2021.

Conclusion

As the United States continues to diversify, the proportion of patients with SoC will continue to grow, and it is imperative that this racial, ethnic, and cultural diversity is reflected in the dermatology workforce as well as research and training. The current deficits in medical training related to SoC populations and the importance for patients with SoC to find dermatologists who can appropriately treat them is well known.²⁹ Skin of color centers/SoCSCs strive to increase access to care for patients with SoC, improve cultural competency, promote diversity among faculty and trainees, and encourage SoC research and education at all levels. We urge academic dermatology training programs to make SoC education, research, and patient care a departmental priority. Important first steps include departmental diversification at all levels, incorporating SoC into curricula for residents, providing and securing funding for SoC research, and supporting the establishment of more formal SoCCs and/or SoCSCs to help reduce dermatologic health care disparities among patients with SoC and improve health equity.

Improved research efforts for SoC must address these deficits in funding, academic support, and other resources.

It also is of great importance for institutions to provide support for trainees wanting to pursue SoC research. Encouragingly, more than half (57.14%) of SoCCs/SoCSCs have developed formal research opportunities for residents, and nearly 64.29% have formal opportunities for medical students. These efforts to provide early experiences in SoC research are especially impactful by cultivating interest in working with populations with SoC and hopefully inspiring future dermatologists to engage in further SoC research.

SoC Education and Diversity Initiatives—Although it is important to increase representation of URiM physicians in dermatology and to train more SoC specialists, it is imperative that all dermatologists feel comfortable recognizing and treating dermatologic conditions in patients of all skin tones and all racial/ethnic backgrounds; however, many studies suggest that residents not only lack formal didactics and education in SoC, but even more unsettling, they also lack confidence in treating SoC.^13,24 However, one study showed that this can be changed; Mhlaba et al²⁵ assessed a SoC curriculum for dermatology residents, and indeed all of the residents indicated that the curriculum improved their ability to treat SoC patients. This deficit in dermatology residency training is specifically addressed by SoCCs/SoCSCs. In our study, all respondents indicated that residents rotate through their centers. Moreover, our study found that most of the academic institutions with SoCCs/SoCSCs provide a SoC didactic curriculum for residents, and almost all of the programs invited SoC specialists to give guest lectures. This is in contrast to a 2022 study showing that 63.2% (N=125) of graduating dermatology residents reported receiving SoC-specific didactics, sessions, or lectures.¹⁴ These findings highlight the critical role that SoCCs/SoCSCs can provide in dermatology residency training.

Although SoCCs/SoCSCs have made considerable progress, there is still much room for improvement. Namely, only half of the respondents in our study indicated that their program has formally incorporated a SoC textbook into resident education (eTable 3). Representation of SoC in the textbooks that dermatology residents use is critically important because these images form the foundation of the morphologic aids of diagnosis. Numerous studies have analyzed popular dermatologic textbooks used by residency programs nationwide, finding the number of SoC images across dermatology textbooks ranging from 4% to 18%.^26,27 The use of standard dermatology textbooks is not enough to train residents to be competent in diagnosing and treating patients with SoC. There should be a concerted effort across the field of dermatology to encourage the development of a SoC educational curriculum at every academic dermatology program, including SoC textbooks, Kodachromes, and online/electronic resources.

Efforts to increase diversity in dermatology and dermatologic training should start in medical school preclinical curriculums and medical student rotations. Although our survey did not assess current medical student curricula, the benefits of academic institutions with SoCCs/SoCSCs are highlighted by the ability for both home and visiting medical students to rotate through the centers and gain early exposure to SoC dermatology. Most of the programs even provide scholarships and/or grants for URiM students to help fund their rotations, which is of critical importance considering the mounting data that the financial burden of visiting rotations disproportionately affects URiM students.²⁸

Study Limitations—Although we did an extensive search and believe to have correctly identified all 15 formal SoCCs/SoCSCs with a high response rate (93.3%), there are institutions that do not have formalized SoCCs/SoCSCs but are known to serve SoC populations. Likewise, there are private dermatology practices not associated with academic centers that have SoC specialists and positively contribute to SoC patient care, research, and education that were not included in this study. Additionally, the data for this study were collected in 2020 and analyzed in 2021, so it is possible that not all SoCCs, divisions, or clinics were included in this study, particularly if established after 2021.

Conclusion

As the United States continues to diversify, the proportion of patients with SoC will continue to grow, and it is imperative that this racial, ethnic, and cultural diversity is reflected in the dermatology workforce as well as research and training. The current deficits in medical training related to SoC populations and the importance for patients with SoC to find dermatologists who can appropriately treat them is well known.²⁹ Skin of color centers/SoCSCs strive to increase access to care for patients with SoC, improve cultural competency, promote diversity among faculty and trainees, and encourage SoC research and education at all levels. We urge academic dermatology training programs to make SoC education, research, and patient care a departmental priority. Important first steps include departmental diversification at all levels, incorporating SoC into curricula for residents, providing and securing funding for SoC research, and supporting the establishment of more formal SoCCs and/or SoCSCs to help reduce dermatologic health care disparities among patients with SoC and improve health equity.

Appendix

Although individuals with skin of color (SoC) are expected to become at least half of the US population by the year 2044, there remains a paucity of education and exposure to treatment of patients with SoC at many dermatology residency programs across the country.¹ One way to improve SoC education has been the formation of specialized clinics, centers, and programs. The first SoC center (SoCC) was established in 1999 at Mount Sinai–St. Luke’s Roosevelt in New York, New York²; since then, at least 13 additional formal SoCCs or SoC specialty clinics (SoCSCs) at US academic dermatology programs have been established.

Skin of color centers serve several important purposes: they improve dermatologic care in patients with SoC, increase research efforts focused on SoC dermatologic conditions, and educate dermatology resident and fellow trainees about SoC. Improving dermatologic care of patients with SoC in the United States is important in providing equitable health care and improving health disparities. Studies have shown that patient-physician racial and cultural concordance can positively impact patient care, increase patient trust and rapport, and improve patient-physician communication, and it can even influence patient decision-making to seek care.^3,4 Unfortunately, even though the US population continues to diversify, the racial/ethnic backgrounds of dermatologists do not parallel this trend; Hispanic and Black physicians comprise 18.9% and 13.6% of the general population, respectively, but represent only 4.2% and 3.0% of dermatologists, respectively.^5-7 This deficit is mirrored by resident and faculty representation, with Black and Latino representation ranging from 3% to 7%.^8-10

Many SoCC’s engage in research focused on dermatologic conditions affecting patients with SoC, which is vital to improving the dermatologic care in this underserved population. Despite increasing recognition of the importance of SoC research, there remains a paucity of clinical trials and research specifically focused on or demonstrating equitable representation of SoC.^11,12

The education and training of future dermatologists is another important area that can be improved by SoCCs. A 2008 study involving 63 chief residents showed that approximately half (52.4% [33/63]) of graduating dermatology residents reported receiving SoC-specific didactics, sessions, or lectures, and 30.2% (19/63) reported having a dedicated rotation where they gained specific experience treating patients with SoC.¹³ A later study in 2022 (N=125) found that 63.2% of graduating dermatology residents reported receiving SoC-specific didactics, sessions, or lectures, and only 11.2% reported having a dedicated rotation where they gained experience treating patients with SoC.¹⁴ These findings suggest that in the last 14 years, formal SoC education—specifically SoC clinical training—has not increased sufficiently.

We conducted a cross-sectional survey study to provide an in-depth analysis of SoCCs and SoCSCs in the United States, including their patient care focus, research, and program diversity.

Methods

We conducted an investigator-initiated, multicenter, cross-sectional survey study of all SoCCs in the United States and their respective academic residency programs. Fifteen formal SoCCs and/or SoCSCs were identified by dermatology program websites and an article by Tull et al² on the state of ethnic skin centers. All programs and centers identified were associated with a dermatology residency program accredited by the Accreditation Council for Graduate Medical Education.

A 42-item questionnaire was sent via email to the directors of these centers and clinics with the intent to collect descriptive information about each of the SoCCs, the diversity of the faculty and residents of the associated dermatology department, current research and funding, diversity and inclusion initiatives, and trainee education from March through April 2020. Data were analyzed using Excel and SPSS statistical software to obtain descriptive statistics including the mean value numeric trends across programs.

This study underwent expedited review and was approved by the University of Southern California (Los Angeles, California) institutional review board (IRB #HS-20-00113). Patient consent was not applicable, as no information was collected about patients.

Results

Fourteen directors from SoCCs/SoCSCs completed the questionnaire (93.3% response rate). Most centers were located in urban areas (12/14 [85.71%]), except for 2 in rural or suburban settings (Table). Most of the SoCCs/SoCSCs were located in the South (5/14 [35.71%]), followed by the Northeast (4/14 [28.57%]), West (3/14 [21.43%]), and Midwest (2/14 [14.29%])(Table). Six (42.86%) of the programs had a SoCSC, 3 (21.43%) had a formal SoCC, and 5 (35.71%) had both. Across all centers, the most common population seen and treated was Black/African American followed by Hispanic/Latino and Asian, respectively. The most commonly seen dermatologic conditions were acne, pigmentary disorders, alopecia, and atopic dermatitis (Figure). The most common cosmetic practice performed for patients with SoC was dermatosis papulosa nigra/seborrheic keratosis removal, followed by laser treatments, skin tag removal, chemical peels, and neuromodulator injections, respectively.

Faculty and Resident Demographics and Areas of Focus—The demographics and diversity of the dermatology faculty and residents at each individual institution also were assessed. The average number of full-time faculty at each institution was 19.4 (range, 2–48), while the average number of full-time faculty who identified as underrepresented in medicine (URiM) was 2.1 (range, 0–5). The average number of residents at each institution was 17.1 (range, 10–31), while the average number of URiM residents was 1.7 (range, 1–3).

Comment

As the number of SoCCs/SoCSCs in the United States continues to grow, it is important to highlight their programmatic, research, and educational accomplishments to show the benefits of such programs, including their ability to increase access to culturally competent and inclusive care for diverse patient populations. One study found that nearly 92% of patients in the United States seen by dermatologists are White.¹⁵ Although studies have shown that Hispanic/Latino and Black patients are less likely to seek care from a dermatologist,^16,17 there is no indication that these patients have a lesser need for such specialty care. Additionally, outcomes of common dermatologic conditions often are poorer in SoC populations.¹⁵ The dermatologists leading SoCCs/SoCSCs are actively working to reverse these trends, with Black and Hispanic/Latino patients representing the majority of their patients.

Faculty and Resident Demographics and Areas of Focus—Although there are increased diversity efforts in dermatology and the medical profession more broadly, there still is much work to be done. While individuals with SoC now comprise more than 35% of the US population, only 12% of dermatology residents and 6% of academic dermatology faculty identify as either Black or Hispanic/Latino.^5,8,10 These numbers are even more discouraging when considering other URiM racial groups such as Pacific Islander/Native Hawaiians or Native American/American Indians who represent 0% and 0.1% of dermatology faculty, respectively.^8,10 Academic programs with SoCCs/SoCSCs are working to create a space in which these discrepancies in representation can begin to be addressed. Compared to the national 6.8% rate of URiM faculty at academic institutions, those with SoCCs/SoCSCs report closer to 10% of faculty identifying as URiM.¹⁸ Moreover, almost all programs had faculty specialized in at least 1 condition that predominantly affects patients with SoC. This is of critical importance, as the conditions that most commonly affect SoC populations—such as CCCA, hidradenitis suppurativa, and cutaneous lupus—often are understudied, underfunded, underdiagnosed, and undertreated.^19-22

Faculty SoC Research—An important step in narrowing the knowledge gap and improving health care disparities in patients with SoC is to increase SoC research and/or to increase the representation of patients with SoC in research studies. In a 2021 study, a PubMed search of articles indexed for MEDLINE using the terms race/­ethnicity, dyschromia, atopic dermatitis, and acne was conducted to investigate publications pertaining to the top 3 most common chief concerns in patients with SoC. Only 1.6% of studies analyzed (N=74,941) had a specific focus on SoC.¹² A similar study found that among the top 5 ­dermatology-focused research journals, only 3.4% of all research (N=11,003) on the top 3 most common chief concerns in patients with SOC was conducted in patients with SoC.²³ Research efforts focused on dermatologic issues that affect patients with SoC are a priority at SoCCs/SoCSCs. In our study, all respondents indicated that they had at least 1 ongoing observational study; the most commonly studied conditions were CCCA, keloids/hypertrophic scarring, and atopic dermatitis, all of which are conditions that either occur in high frequency or primarily occur in SoC. Only 35.71% (5/14) of respondents had active clinical trials related to SoC, and only 21.43% (3/14) and 28.57% (4/14) had internal and external funding, respectively. Although research efforts are a priority at SoCCs/SoCSCs, our survey study highlights the continued paucity of formal clinical trials as well as funding for SoC-focused research. Improved research efforts for SoC must address these deficits in funding, academic support, and other resources.

It also is of great importance for institutions to provide support for trainees wanting to pursue SoC research. Encouragingly, more than half (57.14%) of SoCCs/SoCSCs have developed formal research opportunities for residents, and nearly 64.29% have formal opportunities for medical students.

Prescriptions for isotretinoin may be influenced by patient demographics, medical comorbidities, and drug safety programs.^1,2 In 1982, isotretinoin was approved by the US Food and Drug Administration for treatment of severe recalcitrant nodulocystic acne that is nonresponsive to conventional therapies such as antibiotics; however, prescriber beliefs regarding the necessity of oral antibiotic failure before isotretinoin is prescribed may be influenced by the provider’s generational age.³ Currently, there is a knowledge gap regarding the impact of provider characteristics, including the year providers completed training, on isotretinoin utilization. The aim of our cross-sectional study was to characterize generational isotretinoin prescribing habits in a large-scale midwestern private practice dermatology group.

Modernizing Medicine (https://www.modmed.com), an electronic medical record software, was queried for all encounters that included both an International Classification of Diseases, Tenth Revision, Clinical Modification diagnosis code L70.0 (acne vulgaris) and a medication prescription from May 2021 to May 2022. Data were collected from a large private practice group with locations across the state of Ohio. Exclusion criteria included provider-patient prescription pairs that included non–acne medication prescriptions, patients seen by multiple providers, and providers who treated fewer than 5 patients with acne during the study period. A mixed-effect multiple logistic regression was performed to analyze whether a patient was ever prescribed isotretinoin, adjusting for individual prescriber, prescriber generation (millennial [1981–1996], Generation X [1965–1980], and baby boomer [1946–1964]),⁴ and patient sex; spironolactone and oral antibiotic prescriptions during the study period were included as additional covariates in a subsequent post hoc analysis. This study utilized data that was fully deidentified in accordance with the US Health Insurance Portability and Accountability Act (HIPAA) Privacy Rule. Approval from an institutional review board was not required.

A total of 18,089 provider-patient prescription pairs were included in our analysis (Table). In our most robust model, female patients were significantly less likely to receive isotretinoin compared with male patients (adjusted OR [aOR], 0.394; P<.01). Millennial providers were significantly more likely to utilize isotretinoin in patients who did not receive antibiotics compared with patients who did receive antibiotics (aOR, 1.693; P<.01). When compared with both Generation X and baby boomers, millennial providers were more likely to prescribe isotretinoin in patients who received antibiotics (aOR, 2.227 [P=.02] and 3.638 [P<.01], respectively).

On any given day, oncologist Mark Lewis, MD, feels like he’s seesawing between two eras of technology. 

One minute, he’s working on sequencing a tumor genome. The next, he’s sifting through pages of disorganized data from a device that has been around for decades: the fax machine. 

“If two doctors’ offices aren’t on the same electronic medical record, one of the main ways to transfer records is still by fax,” said Dr. Lewis, director of gastrointestinal oncology at Intermountain Healthcare in Murray, Utah. “I can go from cutting-edge innovation to relying on, at best, 1980s information technology. It just boggles my mind.”

Dr. Lewis, who has posted about his frustration with fax machines, is far from alone. Oncologists are among the many specialists across the country at the mercy of telecopiers. 

According to a 2021 report by the Office of the National Coordinator for Health Information Technology, fax and mail continue to be the most common methods for hospitals and health systems to exchange care record summaries. In 2019, nearly 8 in 10 hospitals used mail or fax to send and receive health information, the report found. 

Fax machines are still commonplace across the healthcare spectrum, said Robert Havasy, MS, senior director for informatics strategy at the Healthcare Information and Management Systems Society (HIMSS). Inertia, cost, and more pressing priorities for hospitals and medical institutions contribute to the technology sticking around, he explained. 

“Post-COVID, my guess is we’re still at over 50% of healthcare practices using fax for some reason, on a daily basis,” Mr. Havasy said in an interview. “A lot of hospitals just don’t have the time, the money, or the staff to fix that problem because there’s always something a little higher up the priority chain they need to focus on.” 

If, for instance, “you’re going to do a process redesign to reduce hospital total acquired infections, your fax machine replacement might be 10th or 12th on the list. It just never gets up to 1 or 2 because it’s ‘not that much of a problem,’ ” he added.

Or is it?

Administrators may not view fax machines as a top concern, but clinicians who deal with the machines daily see it differently. 

“What worries me is we’re taking records out of an electronic storehouse [and] converting them to a paper medium,” Dr. Lewis said. “And then we are scanning into another electronic storehouse. The more steps, the more can be lost.”

And when information is lost, patient care can be compromised. 

Slower Workflows, Care Concerns

Although there are no published data on fax machine use in oncology specifically, this outdated technology does come into play in a variety of ways along the cancer care continuum. 

Radiation oncologist David R. Penberthy, MD, said patients often seek his cancer center’s expertise for second opinions, and that requires collecting patient records from many different practices. 

“Ideally, it would come electronically, but sometimes it does come by fax,” said Dr. Penberthy, program director of radiation oncology at the University of Virginia School of Medicine in Charlottesville. “The quality of the fax is not always the best. Sometimes it’s literally a fax of a fax. You’re reading something that’s very difficult to read.” 

Orders for new tests are also typically sent and received via fax temporarily while IT teams work to integrate them into the electronic health record (EHR), Dr. Penberthy said. 

Insurers and third-party laboratories often send test results back by fax as well.

“Even if I haven’t actually sent my patient out of our institution, this crucial result may only be entered back into the record as a scanned document from a fax, which is not great because it can get lost in the other results that are reported electronically,” Dr. Lewis said. The risk here is that an ordering physician won’t see these results, which can lead to delayed or overlooked care for patients, he explained.

“To me, it’s like a blind spot,” Dr. Lewis said. “Every time we use a fax, I see it actually as an opportunity for oversight and missed opportunity to collect data.”

Dr. Penberthy said faxing can slow things down at his practice, particularly if he faxes a document to another office but receives no confirmation and has to track down what happened. 

As for cybersecurity, data that are in transit during faxing are generally considered secure and compliant with the Health Insurance Portability and Accountability Act (HIPAA), said Mr. Havasy of HIMSS. However, the Privacy Rule also requires that data remain secure while at rest, which isn’t always possible, he added. 

“That’s where faxes fall down, because generally fax machines are in public, if you will, or open areas in a hospital,” he said. “They just sit on a desk. I don’t know that the next nurse who comes up and looks through that stack was the nurse who was treating the patient.” 

Important decisions or results can also be missed when sent by fax, creating headaches for physicians and care problems for patients. 

Dr. Lewis recently experienced an insurance-related fax mishap over Memorial Day weekend. He believed his patient had access to the antinausea medication he had prescribed. When Dr. Lewis happened to check the fax machine over the weekend, he found a coverage denial for the medication from the insurer but, at that point, had no recourse to appeal because it was a long holiday weekend. 

“Had the denial been sent by an electronic means that was quicker and more readily available, it would have been possible to appeal before the holiday weekend,” he said. 

Hematologist Aaron Goodman, MD, encountered a similar problem after an insurer denied coverage of an expensive cancer drug for a patient and faxed over its reason for the denial. Dr. Goodman was not directly notified that the information arrived and didn’t learn about the denial for a week, he said. 

“There’s no ‘ding’ in my inbox if something is faxed over and scanned,” said Dr. Goodman, associate professor of medicine at UC San Diego Health. “Once I realized it was denied, I was able to rectify it, but it wasted a week of a patient not getting a drug that I felt would be beneficial for them.”

Broader Health Policy Impacts

The use of outdated technology, such as fax machines, also creates ripple effects that burden the health system, health policy experts say. 

Duplicate testing and unnecessary care are top impacts, said Julia Adler-Milstein, PhD, professor of medicine and chief of the division of clinical informatics and digital transformation at the University of California, San Francisco.

Studies show that 20%-30% of the $65 billion spent annually on lab tests is used on unnecessary duplicate tests, and another estimated $30 billion is spent each year on unnecessary duplicate medical imaging. These duplicate tests may be mitigated if hospitals adopt certified EHR technology, research shows.

Still, without EHR interoperability between institutions, new providers may be unaware that tests or past labs for patients exist, leading to repeat tests, said Dr. Adler-Milstein, who researches health IT policy with a focus on EHRs. Patients can sometimes fill in the gaps, but not always. 

“Fax machines only help close information gaps if the clinician is aware of where to seek out the information and there is someone at the other organization to locate and transmit the information in a timely manner,” Dr. Adler-Milstein said. 

Old technology and poor interoperability also greatly affect data collection for disease surveillance and monitoring, said Janet Hamilton, MPH, executive director for the Council of State and Territorial Epidemiologists. This issue was keenly demonstrated during the pandemic, Ms. Hamilton said. 

“It was tragic, quite honestly,” she said. “There was such an immense amount of data that needed to be moved quickly, and that’s when computers are at their best.”

But, she said, “we didn’t have the level of systems in place to do it well.”

Specifically, the lack of electronic case reporting in place during the pandemic — where diagnoses are documented in the record and then immediately sent to the public health system — led to reports that were delayed, not made, or had missing or incomplete information, such as patients’ race and ethnicity or other health conditions, Ms. Hamilton said. 

Incomplete or missing data hampered the ability of public health officials and researchers to understand how the virus might affect different patients.

“If you had a chronic condition like cancer, you were less likely to have a positive outcome with COVID,” Ms. Hamilton said. “But because electronic case reporting was not in place, we didn’t get some of those additional pieces of information. We didn’t have people’s underlying oncology status to then say, ‘Here are individuals with these types of characteristics, and these are the things that happen if they also have a cancer.’” 

Slow, but Steady, Improvements

Efforts at the state and federal levels have targeted improved health information exchange, but progress takes time, Dr. Adler-Milstein said.

Most states have some form of health information exchange, such as statewide exchanges, regional health information organizations, or clinical data registries. Maryland is often held up as a notable example for its health information exchange, Dr. Adler-Milstein noted.

According to Maryland law, all hospitals under the jurisdiction of the Maryland Health Care Commission are required to electronically connect to the state-designated health information exchange. In 2012, Maryland became the first state to connect all its 46 acute care hospitals in the sharing of real-time data. 

The Health Information Technology for Economic and Clinical Health (HITECH) Act provided federal-enhanced Medicaid matching funds to states through 2021 to support efforts to advance electronic exchange. Nearly all states used these funds, and most have identified other sources to sustain the efforts, according to a recent US Government Accountability Office (GAO) report. However, GAO found that small and rural providers are less likely to have the financial and technological resources to participate in or maintain electronic exchange capabilities.

Nationally, several recent initiatives have targeted health data interoperability, including for cancer care. The Centers for Disease Control and Prevention’s Data Modernization Initiative is a multiyear, multi–billion-dollar effort to improve data sharing across the federal and state public health landscape. 

Meanwhile, in March 2024, the Biden-Harris administration launched United States Core Data for Interoperability Plus Cancer. The program will define a recommended minimum set of cancer-related data to be included in a patient’s EHR to enhance data exchange for research and clinical care. 

EHR vendors are also key to improving the landscape, said Dr. Adler-Milstein. Vendors such as Epic have developed strong sharing capabilities for transmitting health information from site to site, but of course, that only helps if providers have Epic, she said. 

“That’s where these national frameworks should help, because we don’t want it to break down by what EHR vendor you have,” she said. “It’s a patchwork. You can go to some places and hear success stories because they have Epic or a state health information exchange, but it’s very heterogeneous. In some places, they have nothing and are using a fax machine.”

Mr. Havasy believes fax machines will ultimately go extinct, particularly as a younger, more digitally savvy generation enters the healthcare workforce. He also foresees that the growing use of artificial intelligence will help eradicate the outdated technology. 

But, Ms. Hamilton noted, “unless we have consistent, ongoing, sustained funding, it is very hard to move off [an older] technology that can work. That’s one of the biggest barriers.” 

“Public health is about protecting the lives of every single person everywhere,” Ms. Hamilton said, “but when we don’t have the data that comes into the system, we can’t achieve our mission.”

On any given day, oncologist Mark Lewis, MD, feels like he’s seesawing between two eras of technology. 

One minute, he’s working on sequencing a tumor genome. The next, he’s sifting through pages of disorganized data from a device that has been around for decades: the fax machine. 

“If two doctors’ offices aren’t on the same electronic medical record, one of the main ways to transfer records is still by fax,” said Dr. Lewis, director of gastrointestinal oncology at Intermountain Healthcare in Murray, Utah. “I can go from cutting-edge innovation to relying on, at best, 1980s information technology. It just boggles my mind.”

Dr. Lewis, who has posted about his frustration with fax machines, is far from alone. Oncologists are among the many specialists across the country at the mercy of telecopiers. 

According to a 2021 report by the Office of the National Coordinator for Health Information Technology, fax and mail continue to be the most common methods for hospitals and health systems to exchange care record summaries. In 2019, nearly 8 in 10 hospitals used mail or fax to send and receive health information, the report found. 

Fax machines are still commonplace across the healthcare spectrum, said Robert Havasy, MS, senior director for informatics strategy at the Healthcare Information and Management Systems Society (HIMSS). Inertia, cost, and more pressing priorities for hospitals and medical institutions contribute to the technology sticking around, he explained. 

“Post-COVID, my guess is we’re still at over 50% of healthcare practices using fax for some reason, on a daily basis,” Mr. Havasy said in an interview. “A lot of hospitals just don’t have the time, the money, or the staff to fix that problem because there’s always something a little higher up the priority chain they need to focus on.” 

If, for instance, “you’re going to do a process redesign to reduce hospital total acquired infections, your fax machine replacement might be 10th or 12th on the list. It just never gets up to 1 or 2 because it’s ‘not that much of a problem,’ ” he added.

Or is it?

Administrators may not view fax machines as a top concern, but clinicians who deal with the machines daily see it differently. 

“What worries me is we’re taking records out of an electronic storehouse [and] converting them to a paper medium,” Dr. Lewis said. “And then we are scanning into another electronic storehouse. The more steps, the more can be lost.”

And when information is lost, patient care can be compromised. 

Slower Workflows, Care Concerns

Although there are no published data on fax machine use in oncology specifically, this outdated technology does come into play in a variety of ways along the cancer care continuum. 

Radiation oncologist David R. Penberthy, MD, said patients often seek his cancer center’s expertise for second opinions, and that requires collecting patient records from many different practices. 

“Ideally, it would come electronically, but sometimes it does come by fax,” said Dr. Penberthy, program director of radiation oncology at the University of Virginia School of Medicine in Charlottesville. “The quality of the fax is not always the best. Sometimes it’s literally a fax of a fax. You’re reading something that’s very difficult to read.” 

Orders for new tests are also typically sent and received via fax temporarily while IT teams work to integrate them into the electronic health record (EHR), Dr. Penberthy said. 

Insurers and third-party laboratories often send test results back by fax as well.

“Even if I haven’t actually sent my patient out of our institution, this crucial result may only be entered back into the record as a scanned document from a fax, which is not great because it can get lost in the other results that are reported electronically,” Dr. Lewis said. The risk here is that an ordering physician won’t see these results, which can lead to delayed or overlooked care for patients, he explained.

“To me, it’s like a blind spot,” Dr. Lewis said. “Every time we use a fax, I see it actually as an opportunity for oversight and missed opportunity to collect data.”

Dr. Penberthy said faxing can slow things down at his practice, particularly if he faxes a document to another office but receives no confirmation and has to track down what happened. 

As for cybersecurity, data that are in transit during faxing are generally considered secure and compliant with the Health Insurance Portability and Accountability Act (HIPAA), said Mr. Havasy of HIMSS. However, the Privacy Rule also requires that data remain secure while at rest, which isn’t always possible, he added. 

“That’s where faxes fall down, because generally fax machines are in public, if you will, or open areas in a hospital,” he said. “They just sit on a desk. I don’t know that the next nurse who comes up and looks through that stack was the nurse who was treating the patient.” 

Important decisions or results can also be missed when sent by fax, creating headaches for physicians and care problems for patients. 

Dr. Lewis recently experienced an insurance-related fax mishap over Memorial Day weekend. He believed his patient had access to the antinausea medication he had prescribed. When Dr. Lewis happened to check the fax machine over the weekend, he found a coverage denial for the medication from the insurer but, at that point, had no recourse to appeal because it was a long holiday weekend. 

“Had the denial been sent by an electronic means that was quicker and more readily available, it would have been possible to appeal before the holiday weekend,” he said. 

Hematologist Aaron Goodman, MD, encountered a similar problem after an insurer denied coverage of an expensive cancer drug for a patient and faxed over its reason for the denial. Dr. Goodman was not directly notified that the information arrived and didn’t learn about the denial for a week, he said. 

“There’s no ‘ding’ in my inbox if something is faxed over and scanned,” said Dr. Goodman, associate professor of medicine at UC San Diego Health. “Once I realized it was denied, I was able to rectify it, but it wasted a week of a patient not getting a drug that I felt would be beneficial for them.”

Broader Health Policy Impacts

The use of outdated technology, such as fax machines, also creates ripple effects that burden the health system, health policy experts say. 

Duplicate testing and unnecessary care are top impacts, said Julia Adler-Milstein, PhD, professor of medicine and chief of the division of clinical informatics and digital transformation at the University of California, San Francisco.

Studies show that 20%-30% of the $65 billion spent annually on lab tests is used on unnecessary duplicate tests, and another estimated $30 billion is spent each year on unnecessary duplicate medical imaging. These duplicate tests may be mitigated if hospitals adopt certified EHR technology, research shows.

Still, without EHR interoperability between institutions, new providers may be unaware that tests or past labs for patients exist, leading to repeat tests, said Dr. Adler-Milstein, who researches health IT policy with a focus on EHRs. Patients can sometimes fill in the gaps, but not always. 

“Fax machines only help close information gaps if the clinician is aware of where to seek out the information and there is someone at the other organization to locate and transmit the information in a timely manner,” Dr. Adler-Milstein said. 

Old technology and poor interoperability also greatly affect data collection for disease surveillance and monitoring, said Janet Hamilton, MPH, executive director for the Council of State and Territorial Epidemiologists. This issue was keenly demonstrated during the pandemic, Ms. Hamilton said. 

“It was tragic, quite honestly,” she said. “There was such an immense amount of data that needed to be moved quickly, and that’s when computers are at their best.”

But, she said, “we didn’t have the level of systems in place to do it well.”

People whose gender identity differs from the sex assigned at birth are referred to as transgender. For some, gender identity may not fit into the binary constructs of male and female but rather falls between, within, or outside this construct. These people often consider themselves nonbinary or gender diverse. As the terminology continues to evolve, current recommendations include referring to this patient population as transgender and gender diverse (TGD) to ensure the broadest inclusivity.¹ In this article, the following terms are used as defined below:

• The terms transgender woman and trans feminine describe persons who were assigned male gender at birth but their affirmed gender is female or nonmasculine.
• The terms transgender man and trans masculine describe persons who were assigned female gender at birth but their affirmed gender is male or nonfeminine.

The US Military’s policies on the service of TGD persons have evolved considerably over the past decade. Initial military policies barred TGD service members (TSMs) from service all together, leading to challenges in accessing necessary health care. The first official memorandum explicitly allowing military service by TGD persons was released on June 30, 2016.² The intention of this memorandum was 2-fold: (1) to allow TGD persons to serve in the military so long as they meet “the rigorous standards for military service and readiness” by fulfilling the same standards and procedures as other military service members, including medical fitness for duty, physical fitness, uniform and grooming, deployability, and retention, and (2) to direct the establishment of new or updated policies to specific departments and prescribe procedures for retention standards, separation from service, in-service transition, and medical coverage.² Several other official policies were released following this initial memorandum that provided more specific guidance on how to implement these policies at the level of the force, unit, and individual service member.

Modifications to the original 2016 policies had varying impacts on transgender health care provision and access.³ At the time of publication of this article, the current policy—the Department of Defense Instruction 1300.28⁴—among others, establishes standards and procedures for the process by which active and reserve TSMs may medically, socially, and legally transition genders within the military. The current policy applies to all military branches and serves as the framework by which each branch currently organizes their gender-affirmation processes (GAP).⁴

There currently are several different GAP models among the military branches.⁵ Each branch has a different model or approach to implementing the current policy, with varying service-specific processes in place for TSMs to access gender-affirming care; however, this may be changing. The Defense Health Agency is in the process of consolidating and streamlining the GAP across the Department of Defense branches in an effort to optimize costs and ensure uniformity of care. Per the Defense Health Agency Procedural Instruction Number 6025.21 published in May 2023, the proposed consolidated model likely will entail a single central transgender health center that provides oversight and guidance for several regional joint-service gender-affirming medical hubs. Patients would either be managed at the level of the hub or be referred to the central site.⁵

Herein, we discuss the importance of gender-affirming care and how military and civilian dermatologists can contribute. We also review disparities in health care and identify areas of improvement.

Benefits of Gender-Affirming Care

Gender-affirming procedures are critical for aligning physical appearance with gender identity. Physical appearance is essential for psychological well-being, operational readiness, and the safety of TSMs.⁶ It is well documented that TGD persons experience suicidal ideation, depression, stigma, discrimination and violence at higher rates than their cisgender peers.^7,8 It is important to recognize that transgender identity is not a mental illness, and these elevated rates have been linked to complex trauma, societal stigma, violence, and discrimination.¹ Other studies have suggested that increased access to gender-affirming interventions may ameliorate these mental health concerns.^1,7-9

The major components of gender-affirming care include hormone therapy, gender confirmation surgery, and mental health care, if needed. These are covered by TRICARE, the health care program for military service members; however, at the time of publication, many of the dermatologic gender-affirming procedures are not covered by TRICARE because they are considered “cosmetic procedures,” which is a term used by insurance companies but does not accurately indicate whether a procedure is medically necessary or not. Newer literature has demonstrated that gender-affirming care positively affects the lives of TGD patients, strengthening the argument that gender-affirming care is a medical necessity and not just cosmetic.¹

Aesthetic Procedures in Gender-Affirming Care

Surgeons, including those within the specialties of oto-laryngology, oral and maxillofacial surgery, urology, gynecology, and plastic surgery, provide major gender-affirming interventions; however, dermatologists may offer less invasive solutions that can serve as a temporary experience prior to undergoing more permanent procedures.Hormonally driven disorders including acne, hair loss, and melasma also are managed by dermatologists, along with scar treatment following surgeries.

Because human variation is expansive and subjective, what is considered feminine or masculine may vary by person, group, culture, and country; therefore, it is imperative to ask patients about their individual aesthetic goals and tailor their treatment accordingly. Feminine and masculine are terms that will be used to describe prototypical appearances and are not meant to define a patient’s current state or ultimate goals. The following procedures and medical interventions are where dermatologists can play an important role in TGD persons’ GAPs.

Botulinum Toxin Injections—Botulinum toxin injection is the most common nonsurgical aesthetic procedure performed around the world.¹⁰ The selective paralysis afforded by botulinum toxin has several uses for people undergoing transition. Aesthetically, the feminine eyebrow tends to be positioned above the orbital rim and is arched with its apex between the lateral limbus and lateral canthus,¹¹ while the masculine eyebrow tends to be flatter and fuller and runs over the orbital rim without a peak. For people seeking a more feminine appearance, an eyebrow lift with botulinum toxin can help reshape the typical flatter masculine eyebrow to give it lateral lift that often is considered more feminine. The targeted muscle is the superolateral orbicularis oculi, which serves as a depressor on the eyebrow. This can be combined with purposefully avoiding total lateral frontalis paralysis, which leads to a “Spock” brow for extra lift. Conversely, a naturally arched and higher eyebrow can be flattened and lowered by selectively targeting areas of the frontalis muscle.

Broad square jawlines typically are considered a masculine feature and are another area where botulinum toxin can be used to feminize a patient’s facial features. Targeting the masseter muscle induces muscle weakness, which ultimately may result in atrophy after one or more treatment sessions. This atrophy may lead to narrowing of the lower face and thus may lead to a fuller-appearing midface or overall more heart-shaped face. Every individual’s aesthetic goals are unique and therefore should be discussed prior to any treatment.

Dermal Fillers—Dermal fillers are gel-like substances injected under the skin for subtle contouring of the face. Fillers also can be used to help promote a more masculine or feminine appearance. Filler can be placed in the lips to create a fuller, more projected, feminine-appearing lip. Malar cheek and central lower chin filler can be used to help define a heart-shaped face by accentuating the upper portion of the face and creating a more pointed chin, respectively. Alternatively, filler can be used to masculinize the chin by placing it where it can increase jawline squareness and increase anterior jaw projection. Additionally, filler at the angle of the jaw can help accentuate a square facial shape and a more defined jawline. Although not as widely practiced, lateral brow filler can create a heavier-appearing and broader forehead for a more masculine appearance. These procedures can be combined with the previously mentioned botulinum toxin procedures for a synergistic effect.

Deoxycholic Acid—Deoxycholic acid is an injectable product used to selectively remove unwanted fat. It currently is approved by the US Food and Drug Administration for submental fat, but some providers are experimenting with off-label uses. Buccal fat pad removal—or in this case reduction by dissolution—tends to give a thinner, more feminine facial appearance.¹² Reducing fat around the axillae also can help promote a more masculine upper torso.¹³ The safety of deoxycholic acid in these areas has not been adequately tested; thus, caution should be used when discussing these off-label uses with patients.

Hair and Tattoo Removal—Hair removal may be desired by TGD persons for a variety of reasons. Because cisgender females tend to have less body hair overall, transgender people in pursuit of a more feminine appearance often desire removal of facial, neck, and body hair. Although shaving and other modalities such as waxing and chemical depilatories are readily available at-home options, they are not permanent and may lead to folliculitis or pseudofolliculitis barbae. Laser hair removal (LHR) and electrolysis are modalities provided by dermatologists that tend to be more permanent and lead to better outcomes, including less irritation and better aesthetic appearance. It is important to keep in mind that not every person and not every body site can be safely treated with LHR. Patients with lighter skin types and darker hair tend to have the most effective response with a higher margin of safety, as these features allow the laser energy to be selectively absorbed by the melanin in the hair bulb and not by the background skin pigmentation.^14,15 Inappropriate patient selection or improper settings for wavelength, pulse width, or fluences can lead to burns and permanent scarring.^14,15 Electrolysis is an alternative to hair removal within tattoos and is more effective for those individuals with blonde, red, or white hair.¹⁶

Another novel treatment for unwanted hair is eflor­nithine hydrochloride cream, which works by blocking ornithine decarboxylase, the enzyme that stimulates hair growth. It currently is approved to reduce unwanted hair on the face and adjacent areas under the chin; however the effects of this medication are modest and the medication can be expensive.¹⁷

Cosmetic hair and tattoo removal are not currently covered by TRICARE, except in cases of surgical and donor-site preparation for some GAPs. Individuals may desire removal of tattoos at surgery sites to obtain more natural-appearing skin. Currently, GAPs such as vaginoplasty, phalloplasty, and metoidioplasty—often referred to by patients as “bottom surgeries”—include insurance coverage for tattoo removal, LHR, and/or electrolysis.

Management of Hormonal Adverse Effects

Acne—Individuals on testosterone supplementation tend to develop acne for the first several years of treatment, but it may improve with time.¹⁸ Acne is treated in individuals receiving testosterone the same way as it is treated in cisgender men, with numerous options for topical and oral medications. In trans masculine persons, spironolactone therapy typically is avoided because it may interfere with the actions of exogenous testosterone administered as part of gender-affirming medical treatment and may lead to other undesired adverse effects such as impotence and gynecomastia.¹

Although acne typically improves after starting estrogen therapy, patients receiving estrogens may still develop acne. Most trans feminine patients will already be on an estrogen and an antiandrogen, often spironolactone.¹ Spironolactone often is used as monotherapy for acne control in cisgender women. Additionally, an important factor to consider with spironolactone is the possible adverse effect of increased micturition. Currently, the military rarely has gender-inclusive restroom options, which can create a challenge for TSMs who find themselves needing to use the restroom more frequently in the workplace.

If planning therapy with isotretinoin, dermatologists should discuss several important factors with all patients, including TGD patients. One consideration is the patient’s planned future surgeries. Although new literature shows that isotretinoin does not adversely affect wound healing,¹⁹ some surgeons still adhere to an isotretinoin washout period of 6 to 12 months prior to performing any elective procedures due to concerns about wound healing.^20,21 Second, be sure to properly assess and document pregnancy potential in TGD persons. Providers should not assume that a patient is not pregnant or is not trying to become pregnant just because they are trans masculine. It also is important to note that testosterone is not a reliable birth control method.¹ If a patient still has ovaries, fallopian tubes, and a uterus, they are considered medically capable of pregnancy, and providers should keep this in mind regarding all procedures in the TGD population.

Another newer acne treatment modality is the 1762-nm laser, which targets sebaceous glands.²² This device allows for targeted treatment of acne-prone areas without systemic therapy such as retinoids or antiandrogens. The 1762-nm laser is not widely available but may become a regular treatment option once its benefits are proven over time.

Alopecia and Hyperpigmentation—Androgens, whether endogenously or exogenously derived, can lead to androgenetic alopecia (AGA) in genetically susceptible individuals. Trans masculine persons and others receiving androgen therapy are at higher risk for AGA, which often is undesirable and may be considered gender affirming by some TGD persons. Standard AGA treatments for cisgender men also can be used in trans masculine persons. Some of the most common anti-AGA medications are topical minoxidil, oral finasteride, and oral minoxidil. Although Coleman et al¹ recently reported that finasteride may be an appropriate treatment option in trans masculine persons experiencing alopecia, treatment with 5α-reductase inhibitors may impair clitoral growth and the development of facial and body hair. Further studies are needed to assess the efficacy and safety of 5α-reductase inhibitors in transgender populations.¹ Dutasteride may be used off-label and comes with a similar potential adverse-event profile as finasteride, which includes depression, decreased libido, erectile dysfunction, ejaculation disorders, and gynecomastia.

Conversely, AGA tends to improve in trans feminine persons and others receiving estrogen and antiandrogen therapy. Natural testosterone production is suppressed by estrogens and spironolactone as well as in patients who undergo orchiectomy.¹ Although spironolactone is not approved for acne, AGA, or hirsutism, it is a standard treatment of AGA in cisgender women because it functions to block the effects of androgens, including at the hair follicle. Finasteride may be used for AGA in cisgender women but it is not recommended for trans feminine persons.¹

There are many other modalities available for the treatment of AGA that are less commonly used—some may be cost prohibitive or do not have robust supporting evidence, or both. One example is hair transplantation. Although this procedure gives dramatic results, it typically is performed by a specialized dermatologist, is not covered by insurance, and can cost up to tens of thousands of dollars out-of-pocket. Patients typically require continuous medical management of AGA even after the procedure. Examples of treatment modalities with uncertain supporting evidence are platelet-rich plasma injections, laser combs or hats, and microneedling. Additionally, clascoterone is a topical antiandrogen currently approved for acne, but it is under investigation for the treatment of AGA and may become an additional nonsystemic medication available for AGA in the future.²³

Melasma is a hyperpigmentation disorder related to estrogens, UV light exposure, and sometimes medication use (eg, hormonal birth control, spironolactone).²⁴ The mainstay of treatment is prevention, including sun avoidance as well as use of sun-protective clothing and broad-spectrum sunscreens. Dermatologists tend to recommend physical sunscreens containing zinc oxide, titanium dioxide, and/or iron oxide, as they cover a wider UV spectrum and also provide some protection from visible light. Once melasma is present, dermatologists still have several treatment options. Topical hydroquinone is a proven treatment; however, it must be used with caution to avoid ochronosis. With careful patient selection, chemical peels also are effective treatment options for dyspigmentation and hyperpigmentation. Energy devices such as intense pulsed light and tattoo removal lasers—Q-switched lasers and picosecond pulse widths—also can be used to treat hyperpigmentation. Oral, intralesional, and topical tranexamic acid are newer treatment options for melasma that still are being studied and have shown promising results. Further studies are needed to determine long-term safety and optimal treatment regimens.^24,25

Many insurance carriers, including TRICARE, do not routinely cover medical management of AGA or melasma. Patients should be advised that they likely will have to pay for any medications prescribed and procedures undertaken for these purposes; however, some medication costs can be offset by ordering larger prescription quantities, such as a 90-day supply vs a 30-day supply, as well as utilizing pharmacy discount programs.

Scar Management Following Surgery

In TSMs who undergo gender-affirming surgeries, dermatologists play an important role when scar symptoms develop, including pruritus, tenderness, and/or paresthesia. In the military, some common treatment modalities for symptomatic scars include intralesional steroids with or without 5-fluouroruacil and the fractionated CO₂ laser. There also are numerous experimental treatment options for scars, including intralesional or perilesional botulinum toxin, the pulsed dye laser, or nonablative fractionated lasers. These modalities also may be used on hypertrophic scars or keloids. Another option for keloids is scar excision followed by superficial radiation therapy.²⁶

Mental Health Considerations

Providers must take psychological adverse effects into consideration when considering medical therapies for dermatologic conditions in TGD patients. In particular, it is important to consider the risks for increased rates of depression and suicidal ideation formerly associated with the use of isotretinoin and finasteride, though much of the evidence regarding these risks has been called into question in recent years.^27,28 Nonetheless, it remains prominent in lay media and may be a more important consideration in patients at higher baseline risk.²⁷ Although there are no known studies that have expressly assessed rates of depression or suicidal ideation in TGD patients taking isotretinoin or finasteride, it is well established that TGD persons are at higher baseline risk for depression and suicidality.^1,7,8 All patients should be carefully assessed for depression and suicidal ideation as well as counseled regarding these risks prior to initiating these therapies. If concerns for untreated mental health issues arise during screening and counseling, patients should be referred for assessment by a behavioral health specialist prior to starting therapy.

Future Directions

The future of TGD health care in the military could see an expansion of covered benefits and the development of new dermatologic procedures or medications. Research and policy evolution are necessary to bridge the current gaps in care; however, it is unlikely that all procedures currently considered to be cosmetic will become covered benefits.

Facial LHR is a promising candidate for future coverage for trans feminine persons. When cisgender men develop adverse effects from mandatory daily shaving, LHR is already a covered benefit. Two arguments in support of adding LHR for TGD patients revolve around achieving and maintaining an appearance congruent with their gender along with avoiding unwanted adverse effects related to daily shaving. Visual conformity with one’s affirmed gender has been associated with improvements in well-being, quality of life, and some mental health conditions.²⁹

Scar prevention, treatment, and reduction are additional areas under active research in which dermatologists likely will play a crucial role.^30,31 As more dermatologic procedures are performed on TGD persons, the published data and collective knowledge regarding best practices in this population will continue to grow, which will lead to improved cosmetic and safety outcomes.

Final Thoughts

Although dermatologists do not directly perform gender-affirming surgeries or hormone management, they do play an important role in enhancing a TGD person’s desired appearance and managing possible adverse effects resulting from gender-affirming interventions. There have been considerable advancements in TGD health care over the past decade, but there likely are more changes on the way. As policies and understanding of TGD health care needs evolve, it is crucial that the military health care system adapts to provide comprehensive, accessible, and equitable care, which includes expanding the range of covered dermatologic treatments to fully support the health and readiness of TSMs.

People whose gender identity differs from the sex assigned at birth are referred to as transgender. For some, gender identity may not fit into the binary constructs of male and female but rather falls between, within, or outside this construct. These people often consider themselves nonbinary or gender diverse. As the terminology continues to evolve, current recommendations include referring to this patient population as transgender and gender diverse (TGD) to ensure the broadest inclusivity.¹ In this article, the following terms are used as defined below:

• The terms transgender woman and trans feminine describe persons who were assigned male gender at birth but their affirmed gender is female or nonmasculine.
• The terms transgender man and trans masculine describe persons who were assigned female gender at birth but their affirmed gender is male or nonfeminine.

The US Military’s policies on the service of TGD persons have evolved considerably over the past decade. Initial military policies barred TGD service members (TSMs) from service all together, leading to challenges in accessing necessary health care. The first official memorandum explicitly allowing military service by TGD persons was released on June 30, 2016.² The intention of this memorandum was 2-fold: (1) to allow TGD persons to serve in the military so long as they meet “the rigorous standards for military service and readiness” by fulfilling the same standards and procedures as other military service members, including medical fitness for duty, physical fitness, uniform and grooming, deployability, and retention, and (2) to direct the establishment of new or updated policies to specific departments and prescribe procedures for retention standards, separation from service, in-service transition, and medical coverage.² Several other official policies were released following this initial memorandum that provided more specific guidance on how to implement these policies at the level of the force, unit, and individual service member.

Modifications to the original 2016 policies had varying impacts on transgender health care provision and access.³ At the time of publication of this article, the current policy—the Department of Defense Instruction 1300.28⁴—among others, establishes standards and procedures for the process by which active and reserve TSMs may medically, socially, and legally transition genders within the military. The current policy applies to all military branches and serves as the framework by which each branch currently organizes their gender-affirmation processes (GAP).⁴

There currently are several different GAP models among the military branches.⁵ Each branch has a different model or approach to implementing the current policy, with varying service-specific processes in place for TSMs to access gender-affirming care; however, this may be changing. The Defense Health Agency is in the process of consolidating and streamlining the GAP across the Department of Defense branches in an effort to optimize costs and ensure uniformity of care. Per the Defense Health Agency Procedural Instruction Number 6025.21 published in May 2023, the proposed consolidated model likely will entail a single central transgender health center that provides oversight and guidance for several regional joint-service gender-affirming medical hubs. Patients would either be managed at the level of the hub or be referred to the central site.⁵

Herein, we discuss the importance of gender-affirming care and how military and civilian dermatologists can contribute. We also review disparities in health care and identify areas of improvement.

Benefits of Gender-Affirming Care

Gender-affirming procedures are critical for aligning physical appearance with gender identity. Physical appearance is essential for psychological well-being, operational readiness, and the safety of TSMs.⁶ It is well documented that TGD persons experience suicidal ideation, depression, stigma, discrimination and violence at higher rates than their cisgender peers.^7,8 It is important to recognize that transgender identity is not a mental illness, and these elevated rates have been linked to complex trauma, societal stigma, violence, and discrimination.¹ Other studies have suggested that increased access to gender-affirming interventions may ameliorate these mental health concerns.^1,7-9

The major components of gender-affirming care include hormone therapy, gender confirmation surgery, and mental health care, if needed. These are covered by TRICARE, the health care program for military service members; however, at the time of publication, many of the dermatologic gender-affirming procedures are not covered by TRICARE because they are considered “cosmetic procedures,” which is a term used by insurance companies but does not accurately indicate whether a procedure is medically necessary or not. Newer literature has demonstrated that gender-affirming care positively affects the lives of TGD patients, strengthening the argument that gender-affirming care is a medical necessity and not just cosmetic.¹

Aesthetic Procedures in Gender-Affirming Care

Surgeons, including those within the specialties of oto-laryngology, oral and maxillofacial surgery, urology, gynecology, and plastic surgery, provide major gender-affirming interventions; however, dermatologists may offer less invasive solutions that can serve as a temporary experience prior to undergoing more permanent procedures.Hormonally driven disorders including acne, hair loss, and melasma also are managed by dermatologists, along with scar treatment following surgeries.

Because human variation is expansive and subjective, what is considered feminine or masculine may vary by person, group, culture, and country; therefore, it is imperative to ask patients about their individual aesthetic goals and tailor their treatment accordingly. Feminine and masculine are terms that will be used to describe prototypical appearances and are not meant to define a patient’s current state or ultimate goals. The following procedures and medical interventions are where dermatologists can play an important role in TGD persons’ GAPs.

Botulinum Toxin Injections—Botulinum toxin injection is the most common nonsurgical aesthetic procedure performed around the world.¹⁰ The selective paralysis afforded by botulinum toxin has several uses for people undergoing transition. Aesthetically, the feminine eyebrow tends to be positioned above the orbital rim and is arched with its apex between the lateral limbus and lateral canthus,¹¹ while the masculine eyebrow tends to be flatter and fuller and runs over the orbital rim without a peak. For people seeking a more feminine appearance, an eyebrow lift with botulinum toxin can help reshape the typical flatter masculine eyebrow to give it lateral lift that often is considered more feminine. The targeted muscle is the superolateral orbicularis oculi, which serves as a depressor on the eyebrow. This can be combined with purposefully avoiding total lateral frontalis paralysis, which leads to a “Spock” brow for extra lift. Conversely, a naturally arched and higher eyebrow can be flattened and lowered by selectively targeting areas of the frontalis muscle.

Broad square jawlines typically are considered a masculine feature and are another area where botulinum toxin can be used to feminize a patient’s facial features. Targeting the masseter muscle induces muscle weakness, which ultimately may result in atrophy after one or more treatment sessions. This atrophy may lead to narrowing of the lower face and thus may lead to a fuller-appearing midface or overall more heart-shaped face. Every individual’s aesthetic goals are unique and therefore should be discussed prior to any treatment.

Dermal Fillers—Dermal fillers are gel-like substances injected under the skin for subtle contouring of the face. Fillers also can be used to help promote a more masculine or feminine appearance. Filler can be placed in the lips to create a fuller, more projected, feminine-appearing lip. Malar cheek and central lower chin filler can be used to help define a heart-shaped face by accentuating the upper portion of the face and creating a more pointed chin, respectively. Alternatively, filler can be used to masculinize the chin by placing it where it can increase jawline squareness and increase anterior jaw projection. Additionally, filler at the angle of the jaw can help accentuate a square facial shape and a more defined jawline. Although not as widely practiced, lateral brow filler can create a heavier-appearing and broader forehead for a more masculine appearance. These procedures can be combined with the previously mentioned botulinum toxin procedures for a synergistic effect.

Deoxycholic Acid—Deoxycholic acid is an injectable product used to selectively remove unwanted fat. It currently is approved by the US Food and Drug Administration for submental fat, but some providers are experimenting with off-label uses. Buccal fat pad removal—or in this case reduction by dissolution—tends to give a thinner, more feminine facial appearance.¹² Reducing fat around the axillae also can help promote a more masculine upper torso.¹³ The safety of deoxycholic acid in these areas has not been adequately tested; thus, caution should be used when discussing these off-label uses with patients.

Hair and Tattoo Removal—Hair removal may be desired by TGD persons for a variety of reasons. Because cisgender females tend to have less body hair overall, transgender people in pursuit of a more feminine appearance often desire removal of facial, neck, and body hair. Although shaving and other modalities such as waxing and chemical depilatories are readily available at-home options, they are not permanent and may lead to folliculitis or pseudofolliculitis barbae. Laser hair removal (LHR) and electrolysis are modalities provided by dermatologists that tend to be more permanent and lead to better outcomes, including less irritation and better aesthetic appearance. It is important to keep in mind that not every person and not every body site can be safely treated with LHR. Patients with lighter skin types and darker hair tend to have the most effective response with a higher margin of safety, as these features allow the laser energy to be selectively absorbed by the melanin in the hair bulb and not by the background skin pigmentation.^14,15 Inappropriate patient selection or improper settings for wavelength, pulse width, or fluences can lead to burns and permanent scarring.^14,15 Electrolysis is an alternative to hair removal within tattoos and is more effective for those individuals with blonde, red, or white hair.¹⁶

Another novel treatment for unwanted hair is eflor­nithine hydrochloride cream, which works by blocking ornithine decarboxylase, the enzyme that stimulates hair growth. It currently is approved to reduce unwanted hair on the face and adjacent areas under the chin; however the effects of this medication are modest and the medication can be expensive.¹⁷

Cosmetic hair and tattoo removal are not currently covered by TRICARE, except in cases of surgical and donor-site preparation for some GAPs. Individuals may desire removal of tattoos at surgery sites to obtain more natural-appearing skin. Currently, GAPs such as vaginoplasty, phalloplasty, and metoidioplasty—often referred to by patients as “bottom surgeries”—include insurance coverage for tattoo removal, LHR, and/or electrolysis.

Management of Hormonal Adverse Effects

Acne—Individuals on testosterone supplementation tend to develop acne for the first several years of treatment, but it may improve with time.¹⁸ Acne is treated in individuals receiving testosterone the same way as it is treated in cisgender men, with numerous options for topical and oral medications. In trans masculine persons, spironolactone therapy typically is avoided because it may interfere with the actions of exogenous testosterone administered as part of gender-affirming medical treatment and may lead to other undesired adverse effects such as impotence and gynecomastia.¹

Although acne typically improves after starting estrogen therapy, patients receiving estrogens may still develop acne. Most trans feminine patients will already be on an estrogen and an antiandrogen, often spironolactone.¹ Spironolactone often is used as monotherapy for acne control in cisgender women. Additionally, an important factor to consider with spironolactone is the possible adverse effect of increased micturition. Currently, the military rarely has gender-inclusive restroom options, which can create a challenge for TSMs who find themselves needing to use the restroom more frequently in the workplace.

If planning therapy with isotretinoin, dermatologists should discuss several important factors with all patients, including TGD patients. One consideration is the patient’s planned future surgeries. Although new literature shows that isotretinoin does not adversely affect wound healing,¹⁹ some surgeons still adhere to an isotretinoin washout period of 6 to 12 months prior to performing any elective procedures due to concerns about wound healing.^20,21 Second, be sure to properly assess and document pregnancy potential in TGD persons. Providers should not assume that a patient is not pregnant or is not trying to become pregnant just because they are trans masculine. It also is important to note that testosterone is not a reliable birth control method.¹ If a patient still has ovaries, fallopian tubes, and a uterus, they are considered medically capable of pregnancy, and providers should keep this in mind regarding all procedures in the TGD population.

Another newer acne treatment modality is the 1762-nm laser, which targets sebaceous glands.²² This device allows for targeted treatment of acne-prone areas without systemic therapy such as retinoids or antiandrogens.

One example is hair transplantation. Although this procedure gives dramatic results, it typically is performed by a specialized dermatologist, is not covered by insurance, and can cost up to tens of thousands of dollars out-of-pocket. Patients typically require continuous medical management of AGA even after the procedure. Examples of treatment modalities with uncertain supporting evidence are platelet-rich plasma injections, laser combs or hats, and microneedling. Additionally, clascoterone is a topical antiandrogen currently approved for acne, but it is under investigation for the treatment of AGA and may become an additional nonsystemic medication available for AGA in the future.²³

Melasma is a hyperpigmentation disorder related to estrogens, UV light exposure, and sometimes medication use (eg, hormonal birth control, spironolactone).²⁴ The mainstay of treatment is prevention, including sun avoidance as well as use of sun-protective clothing and broad-spectrum sunscreens. Dermatologists tend to recommend physical sunscreens containing zinc oxide, titanium dioxide, and/or iron oxide, as they cover a wider UV spectrum and also provide some protection from visible light. Once melasma is present, dermatologists still have several treatment options. Topical hydroquinone is a proven treatment; however, it must be used with caution to avoid ochronosis.

Oral, intralesional, and topical tranexamic acid are newer treatment options for melasma that still are being studied and have shown promising results. Further studies are needed to determine long-term safety and optimal treatment regimens.^24,25

Many insurance carriers, including TRICARE, do not routinely cover medical management of AGA or melasma. Patients should be advised that they likely will have to pay for any medications prescribed and procedures undertaken for these purposes; however, some medication costs can be offset by ordering larger prescription quantities, such as a 90-day supply vs a 30-day supply, as well as utilizing pharmacy discount programs.

Scar Management Following Surgery

In TSMs who undergo gender-affirming surgeries, dermatologists play an important role when scar symptoms develop, including pruritus, tenderness, and/or paresthesia. In the military, some common treatment modalities for symptomatic scars include intralesional steroids with or without 5-fluouroruacil and the fractionated CO₂ laser. There also are numerous experimental treatment options for scars, including intralesional or perilesional botulinum toxin, the pulsed dye laser, or nonablative fractionated lasers. These modalities also may be used on hypertrophic scars or keloids. Another option for keloids is scar excision followed by superficial radiation therapy.²⁶

Mental Health Considerations

Providers must take psychological adverse effects into consideration when considering medical therapies for dermatologic conditions in TGD patients. In particular, it is important to consider the risks for increased rates of depression and suicidal ideation formerly associated with the use of isotretinoin and finasteride, though much of the evidence regarding these risks has been called into question in recent years.^27,28 Nonetheless, it remains prominent in lay media and may be a more important consideration in patients at higher baseline risk.²⁷ Although there are no known studies that have expressly assessed rates of depression or suicidal ideation in TGD patients taking isotretinoin or finasteride, it is well established that TGD persons are at higher baseline risk for depression and suicidality.^1,7,8 All patients should be carefully assessed for depression and suicidal ideation as well as counseled regarding these risks prior to initiating these therapies.

Because human variation is expansive and subjective, what is considered feminine or masculine may vary by person, group, culture, and country; therefore, it is imperative to ask patients about their individual aesthetic goals and tailor their treatment accordingly. Feminine and masculine are terms that will be used to describe prototypical appearances and are not meant to define a patient’s current state or ultimate goals. The following procedures and medical interventions are where dermatologists can play an important role in TGD persons’ GAPs.

Botulinum Toxin Injections—Botulinum toxin injection is the most common nonsurgical aesthetic procedure performed around the world.¹⁰ The selective paralysis afforded by botulinum toxin has several uses for people undergoing transition. Aesthetically, the feminine eyebrow tends to be positioned above the orbital rim and is arched with its apex between the lateral limbus and lateral canthus,¹¹ while the masculine eyebrow tends to be flatter and fuller and runs over the orbital rim without a peak. For people seeking a more feminine appearance, an eyebrow lift with botulinum toxin can help reshape the typical flatter masculine eyebrow to give it lateral lift that often is considered more feminine. The targeted muscle is the superolateral orbicularis oculi, which serves as a depressor on the eyebrow. This can be combined with purposefully avoiding total lateral frontalis paralysis, which leads to a “Spock” brow for extra lift. Conversely, a naturally arched and higher eyebrow can be flattened and lowered by selectively targeting areas of the frontalis muscle.

Broad square jawlines typically are considered a masculine feature and are another area where botulinum toxin can be used to feminize a patient’s facial features. Targeting the masseter muscle induces muscle weakness, which ultimately may result in atrophy after one or more treatment sessions. This atrophy may lead to narrowing of the lower face and thus may lead to a fuller-appearing midface or overall more heart-shaped face. Every individual’s aesthetic goals are unique and therefore should be discussed prior to any treatment.

Dermal Fillers—Dermal fillers are gel-like substances injected under the skin for subtle contouring of the face. Fillers also can be used to help promote a more masculine or feminine appearance. Filler can be placed in the lips to create a fuller, more projected, feminine-appearing lip. Malar cheek and central lower chin filler can be used to help define a heart-shaped face by accentuating the upper portion of the face and creating a more pointed chin, respectively. Alternatively, filler can be used to masculinize the chin by placing it where it can increase jawline squareness and increase anterior jaw projection. Additionally, filler at the angle of the jaw can help accentuate a square facial shape and a more defined jawline. Although not as widely practiced, lateral brow filler can create a heavier-appearing and broader forehead for a more masculine appearance. These procedures can be combined with the previously mentioned botulinum toxin procedures for a synergistic effect.

Deoxycholic Acid—Deoxycholic acid is an injectable product used to selectively remove unwanted fat. It currently is approved by the US Food and Drug Administration for submental fat, but some providers are experimenting with off-label uses. Buccal fat pad removal—or in this case reduction by dissolution—tends to give a thinner, more feminine facial appearance.¹² Reducing fat around the axillae also can help promote a more masculine upper torso.¹³ The safety of deoxycholic acid in these areas has not been adequately tested; thus, caution should be used when discussing these off-label uses with patients.

Hair and Tattoo Removal—Hair removal may be desired by TGD persons for a variety of reasons. Because cisgender females tend to have less body hair overall, transgender people in pursuit of a more feminine appearance often desire removal of facial, neck, and body hair. Although shaving and other modalities such as waxing and chemical depilatories are readily available at-home options, they are not permanent and may lead to folliculitis or pseudofolliculitis barbae. Laser hair removal (LHR) and electrolysis are modalities provided by dermatologists that tend to be more permanent and lead to better outcomes, including less irritation and better aesthetic appearance. It is important to keep in mind that not every person and not every body site can be safely treated with LHR. Patients with lighter skin types and darker hair tend to have the most effective response with a higher margin of safety, as these features allow the laser energy to be selectively absorbed by the melanin in the hair bulb and not by the background skin pigmentation.^14,15 Inappropriate patient selection or improper settings for wavelength, pulse width, or fluences can lead to burns and permanent scarring.^14,15 Electrolysis is an alternative to hair removal within tattoos and is more effective for those individuals with blonde, red, or white hair.¹⁶

Another novel treatment for unwanted hair is eflor­nithine hydrochloride cream, which works by blocking ornithine decarboxylase, the enzyme that stimulates hair growth. It currently is approved to reduce unwanted hair on the face and adjacent areas under the chin; however the effects of this medication are modest and the medication can be expensive.¹⁷

Cosmetic hair and tattoo removal are not currently covered by TRICARE, except in cases of surgical and donor-site preparation for some GAPs. Individuals may desire removal of tattoos at surgery sites to obtain more natural-appearing skin. Currently, GAPs such as vaginoplasty, phalloplasty, and metoidioplasty—often referred to by patients as “bottom surgeries”—include insurance coverage for tattoo removal, LHR, and/or electrolysis.

Management of Hormonal Adverse Effects

Acne—Individuals on testosterone supplementation tend to develop acne for the first several years of treatment, but it may improve with time.¹⁸ Acne is treated in individuals receiving testosterone the same way as it is treated in cisgender men, with numerous options for topical and oral medications. In trans masculine persons, spironolactone therapy typically is avoided because it may interfere with the actions of exogenous testosterone administered as part of gender-affirming medical treatment and may lead to other undesired adverse effects such as impotence and gynecomastia.¹

Although acne typically improves after starting estrogen therapy, patients receiving estrogens may still develop acne. Most trans feminine patients will already be on an estrogen and an antiandrogen, often spironolactone.¹ Spironolactone often is used as monotherapy for acne control in cisgender women. Additionally, an important factor to consider with spironolactone is the possible adverse effect of increased micturition. Currently, the military rarely has gender-inclusive restroom options, which can create a challenge for TSMs who find themselves needing to use the restroom more frequently in the workplace.

If planning therapy with isotretinoin, dermatologists should discuss several important factors with all patients, including TGD patients. One consideration is the patient’s planned future surgeries. Although new literature shows that isotretinoin does not adversely affect wound healing,¹⁹ some surgeons still adhere to an isotretinoin washout period of 6 to 12 months prior to performing any elective procedures due to concerns about wound healing.^20,21 Second, be sure to properly assess and document pregnancy potential in TGD persons. Providers should not assume that a patient is not pregnant or is not trying to become pregnant just because they are trans masculine. It also is important to note that testosterone is not a reliable birth control method.¹ If a patient still has ovaries, fallopian tubes, and a uterus, they are considered medically capable of pregnancy, and providers should keep this in mind regarding all procedures in the TGD population.

Another newer acne treatment modality is the 1762-nm laser, which targets sebaceous glands.²² This device allows for targeted treatment of acne-prone areas without systemic therapy such as retinoids or antiandrogens. The 1762-nm laser is not widely available but may become a regular treatment option once its benefits are proven over time.

Alopecia and Hyperpigmentation—Androgens, whether endogenously or exogenously derived, can lead to androgenetic alopecia (AGA) in genetically susceptible individuals. Trans masculine persons and others receiving androgen therapy are at higher risk for AGA, which often is undesirable and may be considered gender affirming by some TGD persons. Standard AGA treatments for cisgender men also can be used in trans masculine persons. Some of the most common anti-AGA medications are topical minoxidil, oral finasteride, and oral minoxidil. Although Coleman et al¹ recently reported that finasteride may be an appropriate treatment option in trans masculine persons experiencing alopecia, treatment with 5α-reductase inhibitors may impair clitoral growth and the development of facial and body hair. Further studies are needed to assess the efficacy and safety of 5α-reductase inhibitors in transgender populations.¹ Dutasteride may be used off-label and comes with a similar potential adverse-event profile as finasteride, which includes depression, decreased libido, erectile dysfunction, ejaculation disorders, and gynecomastia.

Conversely, AGA tends to improve in trans feminine persons and others receiving estrogen and antiandrogen therapy. Natural testosterone production is suppressed by estrogens and spironolactone as well as in patients who undergo orchiectomy.¹ Although spironolactone is not approved for acne, AGA, or hirsutism, it is a standard treatment of AGA in cisgender women because it functions to block the effects of androgens, including at the hair follicle. Finasteride may be used for AGA in cisgender women but it is not recommended for trans feminine persons.¹

There are many other modalities available for the treatment of AGA that are less commonly used—some may be cost prohibitive or do not have robust supporting evidence, or both. One example is hair transplantation. Although this procedure gives dramatic results, it typically is performed by a specialized dermatologist, is not covered by insurance, and can cost up to tens of thousands of dollars out-of-pocket. Patients typically require continuous medical management of AGA even after the procedure. Examples of treatment modalities with uncertain supporting evidence are platelet-rich plasma injections, laser combs or hats, and microneedling. Additionally, clascoterone is a topical antiandrogen currently approved for acne, but it is under investigation for the treatment of AGA and may become an additional nonsystemic medication available for AGA in the future.²³

Melasma is a hyperpigmentation disorder related to estrogens, UV light exposure, and sometimes medication use (eg, hormonal birth control, spironolactone).²⁴ The mainstay of treatment is prevention, including sun avoidance as well as use of sun-protective clothing and broad-spectrum sunscreens. Dermatologists tend to recommend physical sunscreens containing zinc oxide, titanium dioxide, and/or iron oxide, as they cover a wider UV spectrum and also provide some protection from visible light. Once melasma is present, dermatologists still have several treatment options. Topical hydroquinone is a proven treatment; however, it must be used with caution to avoid ochronosis. With careful patient selection, chemical peels also are effective treatment options for dyspigmentation and hyperpigmentation. Energy devices such as intense pulsed light and tattoo removal lasers—Q-switched lasers and picosecond pulse widths—also can be used to treat hyperpigmentation. Oral, intralesional, and topical tranexamic acid are newer treatment options for melasma that still are being studied and have shown promising results. Further studies are needed to determine long-term safety and optimal treatment regimens.^24,25

Many insurance carriers, including TRICARE, do not routinely cover medical management of AGA or melasma. Patients should be advised that they likely will have to pay for any medications prescribed and procedures undertaken for these purposes; however, some medication costs can be offset by ordering larger prescription quantities, such as a 90-day supply vs a 30-day supply, as well as utilizing pharmacy discount programs.

Scar Management Following Surgery

In TSMs who undergo gender-affirming surgeries, dermatologists play an important role when scar symptoms develop, including pruritus, tenderness, and/or paresthesia. In the military, some common treatment modalities for symptomatic scars include intralesional steroids with or without 5-fluouroruacil and the fractionated CO₂ laser. There also are numerous experimental treatment options for scars, including intralesional or perilesional botulinum toxin, the pulsed dye laser, or nonablative fractionated lasers. These modalities also may be used on hypertrophic scars or keloids. Another option for keloids is scar excision followed by superficial radiation therapy.²⁶

Mental Health Considerations

Providers must take psychological adverse effects into consideration when considering medical therapies for dermatologic conditions in TGD patients. In particular, it is important to consider the risks for increased rates of depression and suicidal ideation formerly associated with the use of isotretinoin and finasteride, though much of the evidence regarding these risks has been called into question in recent years.^27,28 Nonetheless, it remains prominent in lay media and may be a more important consideration in patients at higher baseline risk.²⁷ Although there are no known studies that have expressly assessed rates of depression or suicidal ideation in TGD patients taking isotretinoin or finasteride, it is well established that TGD persons are at higher baseline risk for depression and suicidality.^1,7,8 All patients should be carefully assessed for depression and suicidal ideation as well as counseled regarding these risks prior to initiating these therapies. If concerns for untreated mental health issues arise during screening and counseling, patients should be referred for assessment by a behavioral health specialist prior to starting therapy.

Future Directions

The future of TGD health care in the military could see an expansion of covered benefits and the development of new dermatologic procedures or medications. Research and policy evolution are necessary to bridge the current gaps in care; however, it is unlikely that all procedures currently considered to be cosmetic will become covered benefits.

Facial LHR is a promising candidate for future coverage for trans feminine persons. When cisgender men develop adverse effects from mandatory daily shaving, LHR is already a covered benefit. Two arguments in support of adding LHR for TGD patients revolve around achieving and maintaining an appearance congruent with their gender along with avoiding unwanted adverse effects related to daily shaving. Visual conformity with one’s affirmed gender has been associated with improvements in well-being, quality of life, and some mental health conditions.²⁹

Scar prevention, treatment, and reduction are additional areas under active research in which dermatologists likely will play a crucial role.^30,31 As more dermatologic procedures are performed on TGD persons, the published data and collective knowledge regarding best practices in this population will continue to grow, which will lead to improved cosmetic and safety outcomes.

Final Thoughts

Although dermatologists do not directly perform gender-affirming surgeries or hormone management, they do play an important role in enhancing a TGD person’s desired appearance and managing possible adverse effects resulting from gender-affirming interventions. There have been considerable advancements in TGD health care over the past decade, but there likely are more changes on the way. As policies and understanding of TGD health care needs evolve, it is crucial that the military health care system adapts to provide comprehensive, accessible, and equitable care, which includes expanding the range of covered dermatologic treatments to fully support the health and readiness of TSMs.

Results from the latest survey by the National Comprehensive Cancer Network (NCCN) showed that numerous critical systemic anticancer therapies, primarily generic drugs, are currently in shortage.

Nearly 90% of the 28 NCCN member centers who responded to the survey, conducted between May 28 and June 11, said they were experiencing a shortage of at least one drug.

“Many drugs that are currently in shortage form the backbones of effective multiagent regimens across both curative and palliative treatment settings,” NCCN’s CEO Crystal S. Denlinger, MD, said in an interview.

The good news is that carboplatin and cisplatin shortages have fallen dramatically since 2023. At the peak of the shortage in 2023, 93% of centers surveyed reported experiencing a shortage of carboplatin and 70% were experiencing a shortage of cisplatin, whereas in 2024, only 11% reported a carboplatin shortage and 7% reported a cisplatin shortage.

“Thankfully, the shortages for carboplatin and cisplatin are mostly resolved at this time,” Dr. Denlinger said.

However, all three NCCN surveys conducted in the past year, including the most recent one, have found shortages of various chemotherapies and supportive care medications, which suggests this is an ongoing issue affecting a significant spectrum of generic drugs.

“The acute crisis associated with the shortage of carboplatin and cisplatin was a singular event that brought the issue into the national spotlight,” but it’s “important to note that the current broad drug shortages found on this survey are not new,” said Dr. Denlinger.

In the latest survey, 89% of NCCN centers continue to report shortages of one or more drugs, and 75% said they are experiencing shortages of two or more drugs.

Overall, 57% of centers are short on vinblastine, 46% are short on etoposide, and 43% are short on topotecan. Other common chemotherapy and supportive care agents in short supply include dacarbazine (18% of centers) as well as 5-fluorouracil (5-FU) and methotrexate (14% of centers).

In 2023, however, shortages of methotrexate and 5-FU were worse, with 67% of centers reporting shortages of methotrexate and 26% of 5-FU.

In the current survey, 75% of NCCN centers also noted they were aware of drug shortages within community practices in their area, and more than one in four centers reported treatment delays requiring additional prior authorization.

Cancer drug shortages impact not only routine treatments but also clinical trials. The recent survey found that 43% of respondents said drug shortages disrupted clinical trials at their center. The biggest issues centers flagged included greater administrative burdens, lower patient enrollment, and fewer open trials.

How are centers dealing with ongoing supply issues?

Top mitigation strategies include reducing waste, limiting use of current stock, and adjusting the timing and dosage within evidence-based ranges.

“The current situation underscores the need for sustainable, long-term solutions that ensure a stable supply of high-quality cancer medications,” Alyssa Schatz, MSW, NCCN senior director of policy and advocacy, said in a news release.

Three-quarters (75%) of survey respondents said they would like to see economic incentives put in place to encourage the high-quality manufacturing of medications, especially generic versions that are often in short supply. Nearly two-thirds (64%) cited a need for a broader buffer stock payment, and the same percentage would like to see more information on user experiences with various generic suppliers to help hospitals contract with those engaging in high-quality practices.

The NCCN also continues to work with federal regulators, agencies, and lawmakers to implement long-term solutions to cancer drug shortages.

“The federal government has a key role to play in addressing this issue,” Ms. Schatz said. “Establishing economic incentives, such as tax breaks or manufacturing grants for generic drugmakers, will help support a robust and resilient supply chain — ultimately safeguarding care for people with cancer across the country.”
