Socioeconomic status appears to play a key role in affecting mortality and the frequency of severe pulmonary disease among African American scleroderma patients when compared with other groups, according to findings from an analysis of single-center cohort data over a 10-year period.

Indeed, among patients in the cohort of 402 scleroderma patients at MedStar Georgetown University Hospital in Washington, lower household income was predictive of higher mortality during follow-up, independent of race, according to first author Duncan F. Moore, MD, and his colleagues at the hospital.

Previous studies have demonstrated increased risk for scleroderma in African American patients, who also are more likely than non–African Americans to be diagnosed at a younger age and to have conditions including more diffuse cutaneous disease, more severe restrictive lung disease, more cardiac and renal involvement, and increased mortality, the authors wrote in Arthritis Care & Research.

“We did clearly show that African Americans have worse outcomes and severe pulmonary involvement, but I was surprised that there still was a major contribution of socioeconomic status affecting outcomes for all patients, even though only 10% of our patients were indigent and on medical assistance,” Virginia Steen, MD, senior author of the study and professor of rheumatology at Georgetown University, said in an interview. “I still feel strongly that there are likely genetic issues as to why African Americans have such severe disease. We are eager to learn more from the GRASP [Genome Research in African American Scleroderma Patients] study, which is specifically looking at the genetic issues in African American scleroderma patients,” she said.

Of the 402 scleroderma patients at MedStar Georgetown who were seen during 2006-2016, 202 were African American. A total of 186 African American and 184 non–African American patients in the study met the 2013 American College of Rheumatology/European League Against Rheumatism criteria for systemic sclerosis (SSc). Demographics including gender (87% female) and age (mean of 48 years) were similar between the groups.

Overall, the African American patients showed more severe lung disease, more pulmonary hypertension, and more severe cardiac involvement than did non–African American patients, and autoantibodies were significantly different between the groups.

During follow-up, mortality proved much higher among African Americans at 21%, compared with 11% in non–African Americans (P = .005). However, the unadjusted hazard ratio for death declined from 2.061 (P = .006) to a nonsignificant 1.256 after adjustment for socioeconomic variables.

All socioeconomic measures showed significant differences between the groups. African Americans were more likely to be single and disabled at the initial study visit and to have Medicaid, but they were less likely to be a homemaker, have private insurance, or have a college degree. African Americans’ $74,000 median household income (based on ZIP code) was also a statistically significant $23,000 less than non–African American patients. But the researchers noted that “for every additional $10,000 of household income, independent of race, the hazard of death during follow-up declined by 15.5%.”

Notable differences in antibodies appeared between the groups, with more African American patients having isolated nucleolar ANA, anti-U1RNP antibody, or other positive antinuclear antibodies without SSc-specific antibodies. African American patients also were less likely to have anticentromere or anti-RNA polymerase III antibodies.

The study findings were limited by several factors, including possible bias in the matching process and the use of only index values for socioeconomic variables, the researchers noted.

Regardless of relative socioeconomic and genetic influences, “it is clear that African Americans with scleroderma merit more intensive efforts to facilitate timely diagnosis and access to continued evaluation and suppressive treatment, particularly with respect to cardiopulmonary involvement,” they wrote.

Next steps for research, according to Dr. Steen, include studying clinical subsets of African American patients to try to identify factors to predict outcomes, including the nucleolar pattern ANA, overlap with lupus, history of hypertension, and the relationship with renal crisis.

“We are also looking at whether the African American patients are less responsive to mycophenolate than the non–African American patients. We definitely need to find ways to be more aggressive at identifying and treating African American patients early in their disease,” she added.

The researchers had no financial conflicts to disclose. Dr. Steen serves on the MDedge Rheumatology Editorial Advisory Board.

WASHINGTON – Many patients with vitiligo are interested in treating their condition with vitamins, supplements, or a modified diet, but research on whether these measures have an impact remains limited, Nada Elbuluk, MD, said at the annual meeting of the American Academy of Dermatology.

While the literature suggests that supplements with antioxidant properties benefit patients who are receiving phototherapy for vitiligo, “we need more well designed, controlled studies in the future to know where this belongs in our treatment armamentarium,” said Dr. Elbuluk of the department of dermatology at the University of Southern California, Los Angeles.

During a session at the AAD meeting, Dr. Elbuluk, who is also director of the pigmentary disorders clinic at USC, reviewed the evidence for the use of these adjunctive therapies in patients with vitiligo.
 

Vitamins

The pathogenesis of vitiligo includes the overproduction of reactive oxygen species and oxidative stress, factors that contribute to melanocyte damage and death. In addition, many patients with vitiligo are deficient in certain vitamins and minerals, the basis of the hypothesis that supplementation could be beneficial, according to Dr. Elbuluk.

Vitamin B₁₂ and folic acid contribute to DNA repair, synthesis, and methylation, and researchers have hypothesized that these vitamins also play a role in melanin synthesis. In a review of the literature, Dr. Elbuluk and her colleagues found four studies that evaluated vitamin B₁₂ and folic acid in vitiligo. In one study, a controlled trial in which patients took B₁₂ and folic acid with and without phototherapy, the investigators observed no significant difference in repigmentation between groups. The other three studies were uncontrolled and thus provide an insufficient understanding of the effect of B₁₂ and folic acid, said Dr. Elbuluk.

Vitamin D is involved in melanocyte and keratinocyte growth and differentiation, and inhibits T cell activation. Data indicate that low vitamin D levels are common in patients with vitiligo and comorbid autoimmune diseases. In one study, patients who received narrow-band UVB had an increase in vitamin D levels that could contribute to photo-induced melanogenesis, and an open-label study indicated that patients who took vitamin D daily (without phototherapy) for 6 months had an increase of repigmentation over time. “Topical vitamin D analogs have also been used in vitiligo treatment with varying success,” Dr. Elbuluk noted.

“I check vitamin D levels on my patients and make sure that they are within normal range. But I think the degree of supplementation and its role in vitiligo needs to be further elucidated,” she said. And because vitamin D is fat soluble, there is a risk of toxicity if a patient takes too much.

Vitamin C, vitamin E, and alpha-lipoic acid have antioxidant properties. In a double-blind, randomized, controlled trial, one group of patients took vitamins C and E and alpha-lipoic acid for 2 months before and during treatment with narrow-band UVB twice per week (Clin Exp Dermatol. 2007 Nov;32[6]:631-6). Another group underwent phototherapy without supplementation. A significantly greater proportion of patients who received the antioxidants obtained more than 75% repigmentation compared with those who did not. In another study, 73% of patients who received oral vitamin E and narrow band UVB phototherapy had marked to excellent repigmentation, compared with 55.6% of those who had phototherapy only (J Clin Pharmacol. 2009 Jul;49[7]:852-5).

The results of these studies support the idea that antioxidants can stabilize disease, reduce oxidative stress, and improve the effect of phototherapy, Dr. Elbuluk said.
 

Herbal supplements

Several research teams have examined Ginkgo biloba as a possible treatment for vitiligo. This plant is native to China and has antioxidant and anti-inflammatory properties; its most common side effect is gastrointestinal distress. Because it entails a risk of coagulopathy, it may not be appropriate for patients receiving anticoagulant treatment, Dr. Elbuluk pointed out. In a double-blinded, randomized, controlled trial comparing ginkgo biloba alone with placebo in patients with vitiligo, treatment was associated with cessation of active disease in most patients, and more than 40% of patients receiving ginkgo biloba had 75% repigmentation or more.

Polypodium leucotomos, a fern native to Central and South America, protects against UV radiation damage, modulates the immune system, and has anti-inflammatory and antioxidant effects. It has a good safety profile and is well tolerated at a dose of 240 mg/day, she said. It sometimes causes gastrointestinal discomfort or pruritus. Several randomized, controlled trials in patients with vitiligo showed that supplementation with polypodium leucotomos improves repigmentation, particularly in photo-exposed areas, she noted.

Khellin is an extract from the Mediterranean khella plant that is thought to stimulate melanocyte proliferation and melanogenesis. Several studies have examined khellin supplementation in combination with phototherapy. Khellin can be administered orally or topically and appears to be more beneficial than sunlight or phototherapy alone in stabilizing disease or inducing repigmentation. Oral khellin can cause many side effects, including nausea, transaminitis, and hypotension, so researchers have been more interested in using topical khellin as a liposomal vehicle to improve drug delivery, Dr. Elbuluk said.
 

Minerals

Some patients with vitiligo have deficiencies in zinc and copper. Zinc is an antioxidant that aids wound healing, protects against free radicals, supports melanogenesis, and possibly prevents melanocyte death, but can cause gastrointestinal irritation. Copper, too, is an antioxidant and coenzyme involved in melanogenesis. One study compared topical steroid treatment with and without oral zinc supplementation. Dual treatment was associated with greater repigmentation, but the difference was not statistically significant. No studies have examined copper supplementation, she said.

L-phenylalanine, diet, and green tea

Investigators have proposed that the amino acid L-phenylalanine, a precursor to tyrosine in the pathway of melanin synthesis, might interfere with antibody production against melanocytes. This supplement is administered orally by weight, typically in conjunction with phototherapy or sunlight. Various studies have observed positive outcomes of L-phenylalanine combined with phototherapy or sunlight. L-phenylalanine tends to be safe and has been administered to children with vitiligo.

Many patients with vitiligo “have already tried diets by the time they come to me,” said Dr. Elbuluk. No controlled studies have analyzed the role of diet in the prevention or treatment of vitiligo, but case reports describe gluten-free diets in this population, including one report of a patient with celiac disease whose vitiligo improved after adoption of such a diet. Another case report described a patient without celiac disease who had refractory acrofacial vitiligo, which improved after the adoption of a gluten-free diet. Evidence supports a gluten-free diet for patients with celiac disease, but does not support this challenging diet for people without celiac disease, she pointed out.

Green tea includes catechins, which have antioxidant and anti-inflammatory properties. Its main component is epigallocatechin gallate (EGCG), which is thought to modulate T cell mediated responses. In one animal study, administration of EGCG delayed the onset of vitiligo and decreased the area of depigmentation in a mouse model. Although these findings are promising, clinical trials are needed to determine whether EGCG is beneficial in humans with vitiligo, said Dr. Elbuluk.

The literature on diets and supplementation as treatments for vitiligo has several shortcomings, with studies that used heterogeneous methodologies, and many that used nonstandard outcome measures that have not been validated. Sample sizes often are small, and many trials are uncontrolled. “These limitations make it harder to make sense of the data and have take-home conclusions,” Dr. Elbuluk said.

She had no disclosures.

Green tea includes catechins, which have antioxidant and anti-inflammatory properties. Its main component is epigallocatechin gallate (EGCG), which is thought to modulate T cell mediated responses. In one animal study, administration of EGCG delayed the onset of vitiligo and decreased the area of depigmentation in a mouse model. Although these findings are promising, clinical trials are needed to determine whether EGCG is beneficial in humans with vitiligo, said Dr. Elbuluk.

The literature on diets and supplementation as treatments for vitiligo has several shortcomings, with studies that used heterogeneous methodologies, and many that used nonstandard outcome measures that have not been validated. Sample sizes often are small, and many trials are uncontrolled. “These limitations make it harder to make sense of the data and have take-home conclusions,” Dr. Elbuluk said.

WASHINGTON – During a session at the annual meeting of the American Academy of Dermatology, Adam Friedman, MD, presented on off-label use of immunomodulators for inflammatory skin diseases, the highlights of which he shared with fellow George Washington University dermatologist, A. Yasmine Kirkorian, MD, in an interview following the session.

Dr. Friedman, professor and interim chair of dermatology at George Washington University, Washington, provides his top list of immunomodulators, used off-label, ranging from dapsone and hydroxychloroquine, to pentoxifylline and low-dose naltrexone.

For example, as reflected in PubMed searches, low-dose naltrexone, which has to be compounded, is being used for such diseases as Hailey-Hailey and lichen planopilaris, said Dr. Friedman, who is using it for his mast cell activation syndrome patients. During the interview, he also describes his treatment approach for urticaria.

In his final remarks, Dr. Friedman encourages colleagues to “get creative,” publish, and talk about their experiences with off-label treatments in dermatology, citing the example of an article that mentioned using pioglitazone for lichen planopilaris. This article stimulated interest in using the type 2 diabetes agent pioglitazone to treat this skin disease, he notes.

A skin biopsy of one of the lesions on the right toe showed dermal edema with an associated lymphohistiocytic infiltrate. There are scattered areas of perieccrine involvement and areas of vasculitis. Laboratory work up showed a normal complete blood count, a negative antinuclear antibodies (ANA) titer, a negative double-stranded DNA, normal levels of inflammatory markers, and negative cryoglobulins and cold agglutinins. The patient was diagnosed with pernio. The lesions improved within several weeks. She now wears thicker socks when she is ice skating.

Pernio, also known as chilblains, is an inflammatory condition of the skin triggered by cold exposure. Children, women, and the elderly are at a higher risk.¹ This condition is frequently described in Northwestern Europe and the United Kingdom, especially in those living in houses without central heating.²

Clinically, the lesions appear a few hours or days after cold exposure on the toes, fingers, and in some unusual cases on the nose and the ears. The lesions present as erythematous to violaceous macules, papules, or nodules that in severe cases may blister and ulcerate. The lesions may be asymptomatic, pruritic, or tender. In children, pernio can be associated with the presence of cryoglobulins, cold agglutinins, anorexia nervosa, and genetic interferonopathy; it may precede the diagnosis of chronic myelomonocytic leukemia and may occur as a presenting sign of a blast crisis in acute lymphoblastic leukemia.^3,4 The skin lesions usually resolve within days to a few weeks. Histopathologic analysis shows dermal edema with associated superficial and deep lymphohistiocytic infiltrate and perieccrine involvement.

The differential diagnosis of pernio includes other cold-induced syndromes such as Raynaud’s syndrome, cold panniculitis, cold urticaria, livedo reticularis, acrocyanosis, and chilblain lupus. In chilblain lupus (a form of chronic cutaneous lupus), the lesions may be very similar to pernio but the histopathology is consistent with changes of discoid lupus. Lesions of idiopathic palmoplantar hidradenitis present as erythematous tender nodules on the palms and the soles.⁵ The lesions can be triggered by vigorous physical activity, exposure to moisture, and excessive sweating. White, blue, and red discoloration of the fingers is seen in Raynaud’s phenomenon rather than the fixed erythematous to violaceous macules, papules, or nodules seen in pernio. Patients with erythromelalgia present with red painful palms and soles triggered by heat and, in contrast to pernio, relieved by cooling. Sweet syndrome, a febrile neutrophilic dermatoses, is characterized by tender erythematous papules and plaques with associated systemic symptoms. These patients may have an associated internal malignancy or infection, or the disorder may be triggered by medications or pregnancy.

Our patient had no systemic symptoms, and the pathology didn’t show any neutrophils. When the diagnosis is in doubt, a skin biopsy may help elucidate the diagnosis.

Once the diagnosis of pernio is made, it is recommended to order a complete blood count to rule out blood malignancies and cryoproteins.

Treatment of this condition consists of rewarming the extremity. If rewarming does not improve the patient’s symptoms, systemic treatment with nifedipine may be warranted.

WASHINGTON – A novel, standardized preparation of topical cantharidin effectively cleared lesions in patients with molluscum contagiosum, compared with placebo, according to the results of two trials presented at the annual meeting of the American Academy of Dermatology.

VP-102, a drug-device combination, was well tolerated and was not associated with serious adverse events.

No Food and Drug Administration–approved treatment is available for treating molluscum contagiosum, which is routinely treated with cantharidin, a naturally occurring vesicant.

VP-102 is a novel formulation of 0.7% cantharidin solution, provided in a single-use applicator, to provide consistent delivery and long-term drug stability.

To test the efficacy and safety of VP-102, Lawrence Eichenfield, MD, chief of pediatric and adolescent dermatology at Rady Children’s Hospital–San Diego, and his associates conducted the CAMP-1 (Cantharidin Application in Molluscum Patients) and CAMP-2 phase 3 studies, which had similar designs. The studies enrolled patients with molluscum contagiosum aged 2 years and older who had not received any treatment in the 2 weeks before enrollment. Patients were randomized to VP-102 or vehicle for 12 weeks. Treatment was administered topically to each lesion every 3 weeks for a maximum of four applications, and washed off with soap and warm water 24 hours after application.

The trials’ primary endpoint was the percentage of patients with complete clearance of their lesions. Secondary endpoints were the percentage of patients with complete clearance at 3, 6, and 9 weeks, and decrease in lesions over time. The researchers also assessed safety and tolerability.


In the two studies, 528 patients aged 2-60 years (mean age, approximately 7 years) were randomized to treatment or vehicle. About 30% of participants had prior treatment. The baseline lesion count ranged from 1 to 184.

At day 84, the proportion of patients in the VP-102 arm who achieved complete clearance of lesions was 46% in CAMP-1 and 54% in CAMP-2, compared with 18% and 13%, respectively, among controls (P less than .0001). By day 84, among treated patients, the lesion count had decreased by a mean of 69% in CAMP-1 and 83% in CAMP-2, compared with 20% and 19%, respectively, among controls. Results among controls were “probably consistent with natural history,” Dr. Eichenfield observed.

The researchers observed a high incidence of treatment-emergent adverse events among patients receiving VP-102. “Any crust or vesiculation was considered to be a treatment-emergent adverse event,” Dr. Eichenfield said. Most adverse events were mild, although five patients discontinued the studies because of treatment-emergent adverse events. Vesiculation was a common adverse event in the VP-102 group; pruritus and application-site pain were reported as well.

Verrica Pharmaceuticals developed VP-102 and funded the study. Dr. Eichenfield reported receiving no funding from the company; several other investigators are employees of Verrica, which plans to submit for FDA approval in the second half of 2019.

It’s taken 2 years for family members to convince this 50-year-old black woman to consult dermatology about dark circles on her arms and trunk. The asymptomatic lesions were only faintly discolored at manifestation but have darkened with each recurrence. The 6 lesions she currently has are in the exact locations they originally manifested in.

Convinced she had “ringworm,” the patient tried several different antifungal creams, to no avail. Then her primary care provider prescribed a 2-month course of oral antifungal medication (terbinafine)—again, with no change to the lesions.

The patient is otherwise healthy except for osteoarthritis, for which she takes ibuprofen (800 mg 2 or 3 times a day). She denies any history of seizure, chronic urinary tract infection, or other chronic infection.

EXAMINATION
The 6 perfectly round, uniformly pigmented, dark brown macular lesions on the patient’s arms and trunk range from 2 to 5 cm in diameter. A faint, rusty brown halo can be seen around the periphery of the lesions, giving them a targetoid look. The surfaces of the lesions are completely smooth.

What’s the diagnosis?

DISCUSSION
The list of dark brown, round macules that come and go in the exact same locations is a short one—in fact, it only includes fixed drug eruption (FDE). This is a unique adverse reaction to one of several medications; common culprits are ibuprofen or other NSAIDs, aspirin, members of the sulfa family, penicillin, and several antiseizure medications.

The exact mechanism for this reaction is unknown, but it does appear to involve the localized production of cytokines. There is a range of morphologic presentations for FDE: some lesions are more targetoid than others; some are darker (especially in patients with darker skin) while others are more pink.

Furthermore, many patients develop additional lesions over time. A few, on the other hand, will reach a point at which they stop reacting to the offending product.

Of all the drugs causing FDE, sulfa-based products are among the more consistent offenders. Thus, we always ask about chronic urinary tract infections.

TAKE-HOME LEARNING POINTS

• Fixed drug eruptions (FDE) usually manifest with round, targetoid macules that are occasionally blistery.
• The lesions recur or darken with each “challenge” from the drug, which can be one of several potential offenders.
• The fact that the lesions keep recurring in the same location (ie, fixed) is pathognomic for FDE.
• FDE lesions can occur almost anywhere on the body—even on palms or soles.

The FP suspected that this was an acral lentiginous melanoma (ALM).

The FP considered the various ways to biopsy this lesion. Doing a biopsy of the whole lesion was neither practical, nor desirable, given that the lesion was >2 cm and located on the bottom of the patient’s foot. And while incomplete sampling could result in a false negative result, this lesion was so suspicious for melanoma that any well-performed biopsy would likely produce a diagnosis of melanoma. (Of course if melanoma was not diagnosable with partial sampling, a full excisional biopsy would be needed.)

The FP also debated doing a 6-mm punch biopsy vs a shave biopsy; his intent was to get below some of the deeper pigment. Incisional biopsy done as a small ellipse with suturing was also an option. It would also be the most time consuming.

The FP presented the biopsy options to the patient and explained that the shave biopsy would require a dressing and the punch biopsy would require sutures, which would need to be removed at the next visit. Both biopsy methods would likely cause the foot to be uncomfortable to walk on for several days.

The FP and patient decided to do a deep shave biopsy (saucerization). After administering local anesthesia with lidocaine and epinephrine, the FP performed a deep shave biopsy that included about 1 cm of the darkest and thickest portion of the suspected melanoma.

The biopsy results indicated that the patient had an acral lentiginous melanoma, which measured 0.7 mm at its deepest point in the biopsied portion. The patient was referred to Orthopedics for a wide excision and repair. A sentinel node biopsy was not needed because the lesion was less than 1 mm in depth and there was no ulceration. The surgery and healing time were challenging for the patient, but she did not lose her foot and has remained cancer free.

The FP suspected that this was an acral lentiginous melanoma (ALM).

The FP considered the various ways to biopsy this lesion. Doing a biopsy of the whole lesion was neither practical, nor desirable, given that the lesion was >2 cm and located on the bottom of the patient’s foot. And while incomplete sampling could result in a false negative result, this lesion was so suspicious for melanoma that any well-performed biopsy would likely produce a diagnosis of melanoma.

Testosterone therapy can be personalized for transgender men who begin to develop acne during masculinizing hormone treatment, but patient compatibility will depend upon several factors, advised Jason A. Park and his associates in a research letter to the editor of the Journal of the American Academy of Dermatology.

In a multivariate logistic regression analysis, Mr. Park and his colleagues at Boston University sought to determine the timing of onset of acne in female-to-male transgender patients.

A total of 55 patients undergoing hormone therapy at the Center for Transgender Medicine and Surgery at Boston Medical Center between January 1, 2010, and December 31, 2017 were selected following a systematic chart review. Patients were excluded who were under the age of 18 years, who had been receiving testosterone therapy for less than 2 years, who presented with acne before start of treatment, or whose medical records were incomplete.

Given evidence in prior studies reporting on an association between elevated androgen levels and increased incidence of acne in this patient group, a median serum testosterone level of 630 ng/dL “was used to differentiate between higher and lower levels.”

Acne was found to develop in 9% of transgender men after 3 months and in 18% after 6 months; 38% of the subjects were found to have developed acne at some point during the study after 24 months of treatment. The authors found that acne was “significantly associated with serum testosterone levels higher than 630 ng/dL.” Increased body mass index (BMI), especially in those with positive smoking status, also was associated with an increased incidence of acne, the authors said.

According to several existing studies, transgender men undergoing testosterone therapy tend to develop increased sebum production and acne. Because the systemic and dermatologic virilization effects of testosterone are unpredictable once treatment has started, and because individual goals also are varied (from maximum virilization to only suppressing feminine secondary sex characteristics), Mr. Park and his colleagues suggested that customization may be ideal, provided they do not clash with individual patient transition goals, priorities, risk factors, and other comorbidities that may be present.

The study was funded by the Medical Student Summer Research Program at Boston University. The authors had no conflicts of interest to report.

Reducing fear and anxiety in children undergoing dermatologic procedures is possible with techniques based on cognitive behavioral therapy, according to a report published in Pediatric Dermatology.

For many children, the anticipation of pain and the anxiety about a procedure results in a more painful experience, wrote Andrew M. Armenta of the University of Texas, Galveston, and his colleagues. Preparing children in advance and using cognitive behavioral therapy (CBT) strategies in the moment can help reduce their anxiety.

“CBT is a skill‐based approach that focuses on the present and aims to teach efficient ways of identifying distorted thinking, modifying beliefs, and changing behaviors for a more favorable outcome of real‐life situations,” they wrote.

First, Dr. Armenta and his associates advised, be honest with children about what to expect from a procedure. Evidence does not support phrases such as, “It won’t hurt,” or “It will be over soon,” to reduce anxiety.

Timing the disclosure of a procedure and creating the appropriate setting also can help reduce anxiety. For very young children, short notice of a procedure is often best, with the promise of a small reward or outing afterward. Older children may want some advance notice so they can feel prepared, but their specific concerns should be addressed.

CBT-based techniques include deep breathing and positive coping statements such as “I can do this” for older children, or encouraging them to talk about a family pet or listen to music. Younger children may be distracted with pinwheels, rattles, or songs. “Additionally, in recent years, virtual reality headsets have even proved to be effective distractors, resulting in an overall reduction in both pain and fear,” Dr. Armenta and his associates noted.

Other useful strategies include allowing children to choose their position and location for an injection or procedure when possible. Small children may be able to sit on the lap of an adult, and older children may prefer sitting up to lying down. Avoid physical restraint unless it is absolutely necessary for safety, the researchers emphasized.

Incorporating CBT-based strategies of breathing and distraction with honesty and respectful disclosure of what is being done and why “not only makes practicing pediatric dermatology easier, but also can improve patient adherence to painful procedures,” they said.

No disclosure information was given.

A 36-year-old African-American man presented to our clinic for evaluation of a chronic “rash” on his trunk, arms, and legs that had been present for 3 years. Empiric therapy for tinea corporis, nummular eczema, and confluent and reticulated papillomatosis had failed to improve his lesions.

Physical examination revealed a widespread skin eruption consisting of well-demarcated, hyperpigmented, scaly patches and plaques distributed throughout the patient’s trunk and extremities. Initial biopsies of the skin lesions (performed at an outside institution prior to current presentation) were nondiagnostic.

Over the next several months, the patient developed numerous cutaneous nodules and tumors within the background of his persistent patches and plaques (FIGURE). These nodules and tumors intermittently disappeared and recurred, seemingly independent of therapies including psoralen and ultraviolet A phototherapy (PUVA), interferon, and methotrexate.

WHAT IS YOUR DIAGNOSIS?
HOW WOULD YOU TREAT THIS PATIENT?

 

 

Diagnosis: CD30+ transformed mycosis fungoides

Repeat biopsies ultimately confirmed a diagnosis of mycosis fungoides (MF), a primary cutaneous non-Hodgkin lymphoma of T-cell origin.

Lymphomas occurring in the skin without evidence of disease in other areas of the body at the time of diagnosis are referred to as primary cutaneous lymphomas. They are broadly divided by their cell of origin into cutaneous T-cell and cutaneous B-cell lymphomas. Differentiating primary cutaneous lymphoma from systemic lymphomas with secondary skin involvement is an important distinction, as primary cutaneous lymphomas have different clinical courses and prognoses and require different treatments.¹

One literature review found that 25 unique dermatoses can be mimicked clinically by mycosis fungoides.

MF is the most common type of cutaneous T-cell lymphoma (CTCL), yet it remains an uncommon diagnosis as cutaneous lymphomas comprise only 3.9% of all non-Hodgkin lymphomas.² The CD30+ transformed variant identified in this patient is a rare subtype of MF that is associated with increased morbidity and mortality.³ Other types of CTCL include primary cutaneous anaplastic large cell lymphoma, lymphomatoid papulosis, and adult T-cell leukemia/lymphoma, all of which can resemble MF clinically and are diagnosed by histopathology.

A nonspecific presentation

Patients with MF typically present with a complaint of chronic, slowly progressive skin lesions of various sizes and morphologies including scaly patches, plaques, and tumors, often in skin distributions that are not directly exposed to the sun (often referred to as a “bathing suit” distribution).⁴ Pruritus typically accompanies these skin lesions, and alopecia and poikiloderma are common findings. Patients with more advanced cases may present with generalized erythroderma. This finding should raise concern for progression to Sézary syndrome, a more aggressive type of CTCL that manifests with leukemic involvement of malignant T-cells matching the T-cell clones found in the skin.²

Alopecia is a common manifestation of MF that can be clinically indistinguishable from alopecia areata.⁵ While isolated alopecia is unlikely to be a consequence of MF, alopecia in the setting of widespread patches and plaques should raise suspicion for a diagnosis of MF.

Continue to: Diagnostic dilemma

 

 

Diagnostic dilemma: Condition mimics benign disorders

This case illustrates the diagnostic dilemma posed by MF due to its propensity to mimic more benign skin disorders, both clinically and histologically.² One literature review of MF cases in which the diagnosis was not suspected clinically but was eventually confirmed histopathologically found that 25 unique dermatoses can be mimicked clinically by MF.⁶ The more common conditions that MF can be mistaken for are discussed below. In light of the diagnostic challenge posed by this multitude of morphologic presentations, referral to Dermatology for histopathologic evaluation is a reasonable next step when empiric treatment fails to improve symptoms of these common skin disorders.

Chronic atopic dermatitis (eczema) is characterized by dry skin and severe pruritis, usually associated with lichenified plaques and a history of atopic disease. The pruritic, scaly plaques typical of MF may be misdiagnosed as eczema; however, a distribution involving the “bathing suit” area is more suggestive of MF. Patients with atopic dermatitis are more likely to display a flexural distribution.²

Tinea corporis typically presents as annular, erythematous, pruritic, scaly patches or plaques that are similar to the scaling lesions of MF. Tinea corporis can be distinguished from MF via potassium hydroxide preparation of skin scrapings from an active lesion, which should demonstrate the segmented hyphae characteristic of this infection. If lesions of this type fail to respond to topical antifungal therapy, a skin biopsy may be warranted for further evaluation.

Nummular eczema, like tinea corporis, presents with round, coin-shaped patches that are highly pruritic and can be difficult to distinguish from the pruritic patches of MF. Unlike MF, however, nummular eczema typically is observed in patients with diffusely dry skin⁷; the lack of this finding should prompt consideration of alternative diagnoses, including MF.

Psoriasis classically presents with symmetrically distributed, well-demarcated plaques with prominent scaling that are usually asymptomatic, but may be associated with pruritis. Psoriatic plaques may be difficult to distinguish clinically from the plaques of MF, but their distribution may offer clues; psoriasis typically follows an extensor surface distribution, whereas MF is more commonly identified in a “bathing suit” or generalized distribution.⁴

Tx based on disease extent, impact on quality of life

Staging of MF is the primary determinant of treatment and involves evaluation of skin, lymph node, viscera, and blood involvement. Early-stage MF has a favorable prognosis and can be effectively managed with skin-directed treatments. These include topical corticosteroids, topical nitrogen mustard agents, topical retinoids, and phototherapy (PUVA).⁸ Total skin electron beam therapy has been proven effective in the treatment of refractory and extensive MF, and local radiation therapy also is an effective treatment for isolated cutaneous tumors. Prolonged complete remissions of early-stage MF have been achieved using skin-directed treatments.⁸

In contrast, advanced MF often is treatment refractory and carries a poor prognosis. Systemic treatments such as interferon therapy, oral retinoids, extracorporeal photopheresis, and chemotherapy are added in patients with advanced disease after skin-directed therapy fails to adequately control tumor burden.

Our patient initially was treated with PUVA as well as 6 million U of interferon alfa-2B 3 times weekly, which he eventually elected to discontinue after 8 months because he wanted to father a child. His disease became more widespread after discontinuing these treatments despite interim therapy with clobetasol ointment .05%. His larger nodules and tumors were intermittently treated with local radiation with good response. Methotrexate 15 mg weekly was initiated following his decline after discontinuing PUVA and interferon treatment. Treatment with methotrexate resulted in an overall decrease in his tumor burden and several months of clinical stability.

Early stage mycosis fungoides has a favorable prognosis and can be effectively managed with skin-directed treatments. Advanced MF often is treatment refractory and has a poor prognosis.

Approximately 6 months after initiating methotrexate, his condition notably worsened. He developed generalized erythroderma, systemic symptoms including fever, chills, and unintentional 9.07-kg weight loss, in addition to new findings of palmoplantar keratoderma and nail dystrophy. In light of this systemic progression and concern for developing Sézary syndrome, extracorporeal photopheresis, bexarotene (an oral retinoid) 75 mg twice daily, and interferon alfa-2B 5 million U 3 times weekly were initiated. His condition continued to decline despite these therapies, culminating in a hospital admission for sepsis.

The patient recovered, and his regimen was changed to PUVA 3 times weekly in addition to treatment with intravenous brentuximab 1.8 mg/kg, a monoclonal antibody that targets CD30 receptors. Unfortunately, his condition continued to decline on this treatment regimen, which was subsequently abandoned in favor of chemotherapy with gemcitabine 1980 mg/250 mL normal saline. The patient was improving clinically with each cycle of gemcitabine and the plan was to transition him to extracorporeal photopheresis and bexarotene for maintenance therapy; however, the patient succumbed to his disease and passed away at the age of 37.

Methotrexate 15 mg weekly was initiated following his decline after discontinuing PUVA and interferon treatment. Treatment with methotrexate resulted in an overall decrease in his tumor burden and several months of clinical stability.

Early stage mycosis fungoides has a favorable prognosis and can be effectively managed with skin-directed treatments. Advanced MF often is treatment refractory and has a poor prognosis.

Approximately 6 months after initiating methotrexate, his condition notably worsened. He developed generalized erythroderma, systemic symptoms including fever, chills, and unintentional 9.07-kg weight loss, in addition to new findings of palmoplantar keratoderma and nail dystrophy. In light of this systemic progression and concern for developing Sézary syndrome, extracorporeal photopheresis, bexarotene (an oral retinoid) 75 mg twice daily, and interferon alfa-2B 5 million U 3 times weekly were initiated. His condition continued to decline despite these therapies, culminating in a hospital admission for sepsis.

The patient recovered, and his regimen was changed to PUVA 3 times weekly in addition to treatment with intravenous brentuximab 1.8 mg/kg, a monoclonal antibody that targets CD30 receptors. Unfortunately, his condition continued to decline on this treatment regimen, which was subsequently abandoned in favor of chemotherapy with gemcitabine 1980 mg/250 mL normal saline. The patient was improving clinically with each cycle of gemcitabine and the plan was to transition him to extracorporeal photopheresis and bexarotene for maintenance therapy; however, the patient succumbed to his disease and passed away at the age of 37.

A 36-year-old African-American man presented to our clinic for evaluation of a chronic “rash” on his trunk, arms, and legs that had been present for 3 years. Empiric therapy for tinea corporis, nummular eczema, and confluent and reticulated papillomatosis had failed to improve his lesions.

Physical examination revealed a widespread skin eruption consisting of well-demarcated, hyperpigmented, scaly patches and plaques distributed throughout the patient’s trunk and extremities. Initial biopsies of the skin lesions (performed at an outside institution prior to current presentation) were nondiagnostic.

Over the next several months, the patient developed numerous cutaneous nodules and tumors within the background of his persistent patches and plaques (FIGURE). These nodules and tumors intermittently disappeared and recurred, seemingly independent of therapies including psoralen and ultraviolet A phototherapy (PUVA), interferon, and methotrexate.

WHAT IS YOUR DIAGNOSIS?
HOW WOULD YOU TREAT THIS PATIENT?

 

 

Diagnosis: CD30+ transformed mycosis fungoides

Repeat biopsies ultimately confirmed a diagnosis of mycosis fungoides (MF), a primary cutaneous non-Hodgkin lymphoma of T-cell origin.

Lymphomas occurring in the skin without evidence of disease in other areas of the body at the time of diagnosis are referred to as primary cutaneous lymphomas. They are broadly divided by their cell of origin into cutaneous T-cell and cutaneous B-cell lymphomas. Differentiating primary cutaneous lymphoma from systemic lymphomas with secondary skin involvement is an important distinction, as primary cutaneous lymphomas have different clinical courses and prognoses and require different treatments.¹

One literature review found that 25 unique dermatoses can be mimicked clinically by mycosis fungoides.

MF is the most common type of cutaneous T-cell lymphoma (CTCL), yet it remains an uncommon diagnosis as cutaneous lymphomas comprise only 3.9% of all non-Hodgkin lymphomas.² The CD30+ transformed variant identified in this patient is a rare subtype of MF that is associated with increased morbidity and mortality.³ Other types of CTCL include primary cutaneous anaplastic large cell lymphoma, lymphomatoid papulosis, and adult T-cell leukemia/lymphoma, all of which can resemble MF clinically and are diagnosed by histopathology.

A nonspecific presentation

Patients with MF typically present with a complaint of chronic, slowly progressive skin lesions of various sizes and morphologies including scaly patches, plaques, and tumors, often in skin distributions that are not directly exposed to the sun (often referred to as a “bathing suit” distribution).⁴ Pruritus typically accompanies these skin lesions, and alopecia and poikiloderma are common findings. Patients with more advanced cases may present with generalized erythroderma. This finding should raise concern for progression to Sézary syndrome, a more aggressive type of CTCL that manifests with leukemic involvement of malignant T-cells matching the T-cell clones found in the skin.²

Alopecia is a common manifestation of MF that can be clinically indistinguishable from alopecia areata.⁵ While isolated alopecia is unlikely to be a consequence of MF, alopecia in the setting of widespread patches and plaques should raise suspicion for a diagnosis of MF.

Diagnostic dilemma: Condition mimics benign disorders

This case illustrates the diagnostic dilemma posed by MF due to its propensity to mimic more benign skin disorders, both clinically and histologically.² One literature review of MF cases in which the diagnosis was not suspected clinically but was eventually confirmed histopathologically found that 25 unique dermatoses can be mimicked clinically by MF.⁶ The more common conditions that MF can be mistaken for are discussed below. In light of the diagnostic challenge posed by this multitude of morphologic presentations, referral to Dermatology for histopathologic evaluation is a reasonable next step when empiric treatment fails to improve symptoms of these common skin disorders.

Chronic atopic dermatitis (eczema) is characterized by dry skin and severe pruritis, usually associated with lichenified plaques and a history of atopic disease. The pruritic, scaly plaques typical of MF may be misdiagnosed as eczema; however, a distribution involving the “bathing suit” area is more suggestive of MF. Patients with atopic dermatitis are more likely to display a flexural distribution.²

Tinea corporis typically presents as annular, erythematous, pruritic, scaly patches or plaques that are similar to the scaling lesions of MF. Tinea corporis can be distinguished from MF via potassium hydroxide preparation of skin scrapings from an active lesion, which should demonstrate the segmented hyphae characteristic of this infection. If lesions of this type fail to respond to topical antifungal therapy, a skin biopsy may be warranted for further evaluation.

Nummular eczema, like tinea corporis, presents with round, coin-shaped patches that are highly pruritic and can be difficult to distinguish from the pruritic patches of MF. Unlike MF, however, nummular eczema typically is observed in patients with diffusely dry skin⁷; the lack of this finding should prompt consideration of alternative diagnoses, including MF.

Psoriasis classically presents with symmetrically distributed, well-demarcated plaques with prominent scaling that are usually asymptomatic, but may be associated with pruritis. Psoriatic plaques may be difficult to distinguish clinically from the plaques of MF, but their distribution may offer clues; psoriasis typically follows an extensor surface distribution, whereas MF is more commonly identified in a “bathing suit” or generalized distribution.⁴

Tx based on disease extent, impact on quality of life

Staging of MF is the primary determinant of treatment and involves evaluation of skin, lymph node, viscera, and blood involvement. Early-stage MF has a favorable prognosis and can be effectively managed with skin-directed treatments. These include topical corticosteroids, topical nitrogen mustard agents, topical retinoids, and phototherapy (PUVA).⁸ Total skin electron beam therapy has been proven effective in the treatment of refractory and extensive MF, and local radiation therapy also is an effective treatment for isolated cutaneous tumors. Prolonged complete remissions of early-stage MF have been achieved using skin-directed treatments.⁸

In contrast, advanced MF often is treatment refractory and carries a poor prognosis. Systemic treatments such as interferon therapy, oral retinoids, extracorporeal photopheresis, and chemotherapy are added in patients with advanced disease after skin-directed therapy fails to adequately control tumor burden.

Our patient initially was treated with PUVA as well as 6 million U of interferon alfa-2B 3 times weekly, which he eventually elected to discontinue after 8 months because he wanted to father a child. His disease became more widespread after discontinuing these treatments despite interim therapy with clobetasol ointment .05%. His larger nodules and tumors were intermittently treated with local radiation with good response. Methotrexate 15 mg weekly was initiated following his decline after discontinuing PUVA and interferon treatment. Treatment with methotrexate resulted in an overall decrease in his tumor burden and several months of clinical stability.
