Dermatology

A 90-year-old man was admitted from the Emergency Department (ED) to our inpatient service for difficulty urinating and hematuria. In the ED, a complete blood count (CBC) with differential and a urinalysis were performed. CBC showed a mild normocytic anemia, consistent with the patient’s known chronic kidney disease. The urinalysis revealed moderate blood, trace ketones, proteinuria, small leukocyte esterases, positive nitrites, and more than 182 red blood cells—findings suspicious for a urinary tract infection. Computed tomography of the abdomen and pelvis was notable for a soft-tissue mass in the bladder.

He had a history of coronary artery disease (treated with stent placement), atrial fibrillation, congestive heart failure, hypothyroidism, gastroesophageal reflux disease, gastrointestinal bleeding, chronic obstructive pulmonary disease, a 60-pack-per-year history of tobacco dependence, chronic kidney disease, prostate cancer, benign prostatic hypertrophy, peripheral vascular disease, and gout. Medications included digoxin, metoprolol, torsemide, aspirin, levothyroxine, fluticasone, albuterol, omeprazole, diclofenac, escitalopram, and minocycline.

About 5 years earlier, doctors had discovered a popliteal thrombosis that required emergent thrombectomy of the infragenicular popliteal artery, thromboembolectomy of the right posterior tibial artery, graft angioplasty of the right posterior tibial artery, and right anterior fasciotomy for compartment syndrome.

Ten months later, an abscess formed at the incision site. His physician irrigated the popliteal wound and prescribed intravenous (IV) vancomycin. However, the patient developed an allergy and IV daptomycin was initiated and followed by chronic antibiotic suppression with oral minocycline 100 mg bid for about 3.5 years. Skin discoloration appeared within a year of starting the minocycline.

During his hospitalization on our service, we noted black pigmentation of both legs (FIGURE). He had intact strength and sensation in his legs, 1+ pitting edema, no pain upon palpation, and 2+ distal pulses. The patient was well appearing and in no acute distress.

Diagnosis: Minocycline-induced hyperpigmentation

The patient’s clinical presentation of chronic blue-black hyperpigmentation on the anterior shins of both legs after a prolonged antibiotic course led us to conclude that this was an adverse effect of minocycline. Commonly, doctors use minocycline to treat acne, rosacea, and rheumatoid arthritis. In this case, it was used to provide chronic antimicrobial suppression.

Not an uncommon reaction for a patient like ours. One small study conducted in an orthopedic patient population found that 54% of patients receiving long-term minocycline suppression developed hyperpigmentation after a mean follow-up of nearly 5 years.¹ The hyperpigmentation is solely cosmetic and without known clinical complications, but it can be distressing for patients.

There are 3 types of minocycline-­induced hyperpigmentation:

• Type I is a circumscribed blue-black pigmentation that manifests in skin that previously was inflamed or scarred, such as facial acne scars.² Histopathologic findings include black pigment granules in macrophages and throughout the dermis that stain with Perls Prussian blue iron.³
• Type II (which our patient had) is circumscribed blue-black pigmentation that appears in previously normal skin of the forearms or lower legs—especially the shins.³ On histopathology, black pigment granules are found in the dermis with macrophages that stain with Perls Prussian blue iron and Fontana-Masson.³
• Type III is a diffuse muddy brown hyperpigmentation in previously normal, sun-exposed skin.² Histopathologic findings include increased melanin in basal keratinocytes and dermal melanophages that stain with Fontana-Masson.³

Monitor patients taking minocycline for early signs of pigmentation.

Types II and III may be related to cumulative dosing, whereas type I can occur at any point during treatment.²

Differential includes pigmentation disorders

The differential diagnosis includes Addison disease, argyria, hemochromatosis, and polycythemia vera, which all can cause diffuse blue-gray patches.⁴ Brown-violet pigmentation on sun-exposed areas, redness, and itching are more typical of Riehl melanosis.⁴

Continue to: Diltiazem

Diltiazem can produce slate-gray to blue-gray reticulated hyperpigmentation.⁵ Other drugs that can induce slate-gray macules or patches include amiodarone, chlorpromazine, imipramine, and desipramine.⁵

Treatment is simple, resolution takes time

The treatment for this condition is cessation of minocycline use. Pigmentation fades slowly and may persist for years. There has been successful treatment of type I and III minocycline-induced hyperpigmentation with the alexandrite 755 nm Q-switched laser combined with fractional photothermolysis.^3,6 Unfortunately, insurance coverage is limited because these treatments are cosmetic in nature.

Given that hyperpigmentation is a known adverse effect of minocycline use, it’s important to counsel patients about the possibility prior to initiating treatment. It’s also important to monitor for signs of changing pigmentation to prevent psychological distress.

In this case, a biopsy was deemed unnecessary, as the antibiotic was the most likely cause of the pigmentation. The patient’s outpatient dermatologist recommended changing therapy if a medically appropriate alternative was available. Doxycycline would have been a reasonable alternative; however, the patient died shortly after his presentation to our hospital due to his multiple comorbidities.

The use of topical corticosteroids does not significantly increase fracture risk in young children diagnosed with atopic dermatitis, results from a large population-based study suggest.

LucaLorenzelli/Thinkstock

“Little has been published about the risk of fracture in children with atopic dermatitis on topical corticosteroids specifically,” one of the study authors, Reese L. Imhof, said in an interview following the virtual annual meeting of the Society for Pediatric Dermatology. “There are concerns, particularly among parents, regarding potential bone side effects through possible corticosteroid percutaneous absorption. Fears related to topical corticosteroid use likely stem from the fact that prolonged systemic corticosteroid use is associated with an increased risk of bone fractures.”

In an effort to determine the fracture risk in children who were diagnosed with atopic dermatitis (AD) prior to age 4 years and received topical corticosteroid treatment, Mr. Imhof, from Mayo Medical School, Rochester, Minn., and his associates used the Rochester Epidemiology Project records-linkage system to identify patients in Olmstead County, Minn., who received their first AD diagnosis prior to age 4 years between Jan. 1, 2004, through Dec. 31, 2017. Those who received topical corticosteroids listed in National Drug File-Reference Terminology class 8952 (anti-inflammatory, topical) or 8954 (anti-infective/anti-inflammatory combinations, topical) between Jan. 1, 2004, and Dec. 31, 2018 were included in the analysis and were followed to identify new bone fractures, excluding pathological fractures in neoplastic disease and skull or facial bone fractures.

The researchers conducted two analyses of the data. For the primary statistical analysis, they evaluated topical corticosteroid exposure as a binary time-dependent covariate in a Cox proportional hazard model using age as the time scale, with patients entering the risk set at the age of the first clinic visit rather than the age of their first AD diagnosis. Next, the researchers performed a landmark analysis as a sensitivity analysis. For this, each patient’s fourth birthday was defined as the starting point, since all included patients were diagnosed with AD prior to age 4 years.

Of the 7,505 patients first identified with AD, 3,542 were included in the primary analysis and 2,499 were included in the landmark analysis. In the primary analysis, 2,384 patients (67%) received a topical prescription for a topical corticosteroid prior to age 4 years, and an additional 190 (5%) received their first prescription after age 4 years. The researchers observed that 451 patients (13%) had a fracture after AD diagnosis at a median age of 7.4 years. The median age at last follow-up for the remaining 3,091 patients was 6.6 years. Evaluated as a time-dependent covariate, the use of a topical corticosteroid was associated with a nonsignificant 17% increased risk of fracture (hazard ratio, 1.17; P = .16).

In the landmark analysis, 1,722 patients (69%) were prescribed a topical corticosteroid prior to age 4 years. Of these patients, 333 (13%) had their first fracture after AD diagnosis, at a median age of 8.7 years. The median age at last follow-up for the remaining patients was 9.3 years. The researchers observed that, starting at 4 years of age, there was no association between topical corticosteroid use and risk of fracture (HR, 1.00; P = 1.00).

“Our findings suggest that topical corticosteroids do not significantly increase fracture risk in this pediatric population with atopic dermatitis,” Mr. Imhof said. “Dermatologists can use the results of this study to reassure parents of infants and young children, as most patients in our study received their first topical corticosteroid prescription prior to age 4.”

He acknowledged certain limitations of the study, such as its retrospective design and study population, which was predominantly white and resided in the upper Midwest. “Also, our study examined prescription data with the assumption made that topical corticosteroids were used as prescribed,” he said. “An additional limitation is that we evaluated ever versus never exposure to topical corticosteroids rather than cumulative duration of use and/or potency.”

Mr. Imhof and his colleagues reported having no financial disclosures.

Physicians have been slow to embrace biosimilar versions of infliximab, but are more likely to prescribe it to new patients, based on data from a review of nearly 50,000 infliximab claims through Medicare in the first 2 years that biosimilars were available in the United States.

“Although biosimilar versions are as safe and effective as the biologic, patients and physicians may be more reluctant to switch from a working biologic regimen in a chronic setting than an acute one,” wrote Alice J. Chen, PhD, of the University of Southern California, Los Angeles, and colleagues.

In a research letter published in JAMA Internal Medicine, the investigators examined prescribing patterns of physicians switching between the originator infliximab (Remicade) and two of its biosimilars (Inflectra and Renflexis).

They reviewed infliximab use and reimbursement in the 100% Medicare Part B quarterly claims database from Jan. 1, 2017, to Dec. 31, 2018. The study population included Medicare patients classified as new if they had no infliximab claims in the prior 6 months; those with claims were considered returning patients.

In a comparison of claims reflecting 49,771 patients and 4,289 physicians in 2018, a total of 1,418 new patients (17.4%) and 4,495 (10.8%) returning patients used a biosimilar. “Of returning patients, half used the biosimilar version exclusively, whereas the other half switched between biologic and biosimilar versions,” the researchers noted.

Of the 4,289 physicians who prescribed infliximab, 3,124 prescribed no biosimilars, 1,015 prescribed both biologics and biosimilars, and 150 prescribed biosimilars only. Of the physicians who prescribed both, approximately 61% switched some patients from the biologic to the biosimilar; “the remainder kept individual patients on only 1 version of the drug but treated patients with both versions,” the researchers wrote.

The adoption of biosimilars may be slower for chronic vs. acute conditions, the researchers noted. “Prescribers may hesitate to switch clinically stable chronic patients from biologic regimens if they are unfamiliar with the biosimilar or face financial disincentives from prescribing it.”

The study findings were limited by several factors including the use of only 2 years of data and a focus only on Medicare Part B. Switching medications may have been influenced by factors such as lower copays for patients and rebates or discounts for physicians; however, “further research is needed to better understand biosimilar pricing dynamics and the barriers to adopting biosimilars for chronic conditions,” they concluded.

The study was supported by the Leonard D. Schaeffer Center for Health Policy & Economics at the University of Southern California, Los Angeles, and the National Institute on Aging. Lead author Dr. Chen also disclosed receiving personal fees from Amgen outside of the current study.

Physicians have been slow to embrace biosimilar versions of infliximab, but are more likely to prescribe it to new patients, based on data from a review of nearly 50,000 infliximab claims through Medicare in the first 2 years that biosimilars were available in the United States.

“Although biosimilar versions are as safe and effective as the biologic, patients and physicians may be more reluctant to switch from a working biologic regimen in a chronic setting than an acute one,” wrote Alice J. Chen, PhD, of the University of Southern California, Los Angeles, and colleagues.

In a research letter published in JAMA Internal Medicine, the investigators examined prescribing patterns of physicians switching between the originator infliximab (Remicade) and two of its biosimilars (Inflectra and Renflexis).

They reviewed infliximab use and reimbursement in the 100% Medicare Part B quarterly claims database from Jan. 1, 2017, to Dec. 31, 2018. The study population included Medicare patients classified as new if they had no infliximab claims in the prior 6 months; those with claims were considered returning patients.

In a comparison of claims reflecting 49,771 patients and 4,289 physicians in 2018, a total of 1,418 new patients (17.4%) and 4,495 (10.8%) returning patients used a biosimilar. “Of returning patients, half used the biosimilar version exclusively, whereas the other half switched between biologic and biosimilar versions,” the researchers noted.

Of the 4,289 physicians who prescribed infliximab, 3,124 prescribed no biosimilars, 1,015 prescribed both biologics and biosimilars, and 150 prescribed biosimilars only. Of the physicians who prescribed both, approximately 61% switched some patients from the biologic to the biosimilar; “the remainder kept individual patients on only 1 version of the drug but treated patients with both versions,” the researchers wrote.

The adoption of biosimilars may be slower for chronic vs. acute conditions, the researchers noted. “Prescribers may hesitate to switch clinically stable chronic patients from biologic regimens if they are unfamiliar with the biosimilar or face financial disincentives from prescribing it.”

The study findings were limited by several factors including the use of only 2 years of data and a focus only on Medicare Part B. Switching medications may have been influenced by factors such as lower copays for patients and rebates or discounts for physicians; however, “further research is needed to better understand biosimilar pricing dynamics and the barriers to adopting biosimilars for chronic conditions,” they concluded.

ANSWER

The correct answer is lichen planus (choice “c”).

DISCUSSION

Condyloma accuminata can demonstrate amazing lability, sometimes appearing decades after exposure. And spouses may not always be truthful when questioned about such exposure. To further confuse the issue, it's entirely possible that a patient may be unaware he or she has condyloma. So, this might well have been condyloma. But the differential for penile lesions would include this condition—and more.

Psoriasis (choice “a”) commonly affects the penis, manifesting as pinkish plaques and papules. But there is a good chance that examination would have revealed corroborative signs of this disease. Furthermore, the histologic results would have been entirely different.

While syphilis (choice “b”), especially in its primary stage, can present with nonhealing sores, in no way do they resemble the patient’s lesions. There is also no source for such an infection. And biopsy would have shown a predominately plasma cell infiltrate in an entirely different pattern.

Lichen sclerosus et atrophicus (choice “d”) is quite uncommon, especially on the penis, where it is usually known as balanitis xerotica obliterans (BXO). As its name suggests, BXO is usually atrophic—therefore macular—and whitish. Exclusive to uncircumcised men, it bears no resemblance to condyloma.

Though idiopathic, lichen planus is not contagious. Unless neglected, this condition seldom causes any suffering aside from mental anguish over its appearance. To make a more accurate diagnosis, it is always helpful for providers to consider a mnemonic device for “7 Ps” associated with lichen planus:

• Penile
• Pruritic
• Plaque-like
• Purple
• Papular
• Planar
• Puzzling.

TREATMENT

Fortunately, lichen planus affecting the penis responds readily to treatment with mid-strength topical steroid cream and the "tincture of time," which improves its appearance until it eventually disappears. For this patient, the PCP treated the affected area with triamcinolone 0.1% cream bid for 2 weeks. This was then applied once a day every other day for a month, which cleared the patient’s lesions.

COVID-19 has posed serious questions for patients with psoriatic disease and the clinicians who treat them. Both have serious concerns over whether psoriasis or the medications used to treat it pose additional risk for contracting COVID-19 or experiencing worse outcomes with illness.

At the virtual annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis, experts gathered to discuss these concerns and what is known about the special risk factors for psoriatic disease patients.

Studies from a few registries have been done already among patients with autoimmune disease, and the results so far suggest that patients may be able to breathe a little easier. “I don’t see any data that suggests that use of immunosuppressives or having autoimmune disease increases your risk of acquiring it. I think most of the risk is driven by risk of exposure,” said Kevin Winthrop, MD, MPH, a professor of public health, infectious diseases, ophthalmology at Oregon Health & Science University, Portland, during a presentation.

That assertion was reinforced by data presented by Rebecca Haberman, MD, a rheumatologist at New York University Langone Health. Her group created the Web-Based Assessment of Autoimmune, Immune-Mediated, and Rheumatic Patients during the COVID-19 Pandemic (WARCOV) cohort study to address the question of whether patients with immune-mediated inflammatory disease (IMID), including inflammatory arthritis, psoriasis, or inflammatory bowel disease, should discontinue or modify their immunotherapy regimens in the face of potential exposure to COVID-19.

To date, the study has data on 1,122 patients; 604 with inflammatory arthritis, 128 of whom have tested positive for COVID-19. The team established a cohort using the first 86 IMID patients confirmed to have contracted COVID-19. The hospitalization rate was 16% overall, and use of corticosteroids was associated with increased hospitalization risk. A follow-up analysis looking at the first 103 inflammatory arthritis patients who contracted COVID-19 showed a hospitalization rate of 26% and a mortality of 4%. That hospitalization rate is similar to the general hospitalization rate estimated by the New York Department of Health, Dr. Haberman said in her presentation.

Risk factors associated with hospitalization included being older and having asthma or COPD, which is similar to the general population. Use of oral glucocorticoids was linked to a big increase in risk for hospitalization, even with doses less than 10 mg prednisone daily (odds ratio, 14.31; 95% confidence interval, 3.55-57.70). There were no links between use of any cytokine therapy and risk, but use of TNF inhibitors was associated with a reduced risk (OR, 0.35; 95% CI, 0.13-0.97), while use of JAK inhibitors was associated with greater risk (OR, 6.30; 95% CI, 1.68-23.69). The latter result is tentative because of a small sample size, and it was driven largely by the experiences of patients with psoriatic arthritis.

Another study, run by the COVID-19 Global Rheumatology Alliance, looked at 600 patients with rheumatic disease from 40 countries, and “found no smoking gun,” said Leonard Calabrese, DO, who leads the Cleveland Clinic’s section of clinical immunology, during his presentation. “People can develop this when they’re on hydroxychloroquine. They seem to do not remarkably bad or remarkably good. There is no adverse signal for biologics, but being on prednisone [at a dose of] more than 10 mg is not great,” said Dr. Calabrese, who also noted that other publications have supported these conclusions.

So given these findings, how should clinicians address patient concerns? In the absence of probable exposure, “we say it’s better to have a well-controlled IMID on therapy than a poorly-controlled IMID on submaximal therapy. We say stick to therapy and try to wean the prednisone down as low as possible,” Dr. Calabrese said.

More controversially, what should patients do if they have had a significant exposure, such as a close proximity, prolonged exposure encounter with an individual with documented COVID-19, or at high-risk of disease? Dr. Calabrese noted that the American College of Rheumatology (ACR) guidelines recommend that low-level immunomodulation can be continued, “with an asterisk if it’s hydroxychloroquine, and it is in most of our minds now that we know that it is not effective, and the toxicity in the COVID setting is still being worked out,” he said.

With respect to other immunosuppressants, the ACR recommends stopping them temporarily, although IL-6 inhibitors may be continued in select circumstances. Resumption of the therapeutics can resume after a negative COVID test or completion of a 2-week observation period.

When patients contract COVID-19, antimalarial medications can be continued because they have been studied. “But medium-level immunomodulators, in particular methotrexate, I have grave concerns about because it can inhibit the adaptive immune response and antibody formation,” he said. COVID-19 is a serious infection, and all serious biologics have a package insert saying to stop them in a serious infection. Again, IL-6 inhibitors may be considered an exception in the right circumstances. When to resume these medications remains unknown. “I think that’s a work in progress. Test-based versus clinic-based strategies are a matter of controversy,” Dr. Calabrese said.

Ultimately, the question of what to do with immunosuppressive therapies in this population will continue to be a challenge. “The only good answer is to follow the rules of social distancing and to wear a mask,” said Kristina Callis Duffin, MD, a cochair of the department of dermatology and associate professor of dermatology at the University of Utah, Salt Lake City.

Racial differences in the rates of atopic dermatitis appear to arise early in life, results from a single-center retrospective study found.

“Atopic dermatitis is a very common pediatric skin condition with significant morbidity for patients and their families,” lead study author Reesa L. Monir, MD, said during the virtual annual meeting of the Society for Pediatric Dermatology. “Existing studies show increased disease prevalence in Black and Asian children relative to White children, with conflicting data for Hispanic children. The methodology behind many of these existing studies, however, is somewhat questionable. Many were survey-based studies asking parents to remember a diagnosis of eczema or even asking parents to just report an itchy rash and using that as a diagnosis.”

For the current study, Dr. Monir and colleagues reviewed the records of 4,016 infants born between June 1, 2011, and April 30, 2017, who were followed in the University of Florida’s health care system. The researchers defined this as having two or more well-child visits after birth and at least one visit at 300 days of life or later, and the used documentation of specific ICD-9 or ICD-10 codes to capture an objective diagnosis of atopic dermatitis (AD). Of the 4,016 patients, 39.2% were Black, 38.5% were White, 7.1% were Hispanic, 5.3% were Asian, 6.5% were from other racial backgrounds, and 3.4% were multiracial.

Dr. Monir, who is a resident in the department of dermatology at the University of Florida, Gainesville, reported that Black infants had the highest prevalence of AD at 37%, followed by Asian infants (25.8%), Hispanic infants (24.1%), multiracial infants (23%), infants from other racial backgrounds (19.1%), and non-Hispanic White infants (17.9%). Compared with White infants, the odds ratio estimates for AD was highest for Black infants (OR, 2.62), followed by Asian infants (OR, 1.55), multiracial infants (OR, 1.42), Hispanic infants (OR, 1.41), and infants from other racial backgrounds (OR, .97).

On unadjusted analysis, the following factors were significantly associated with race: delivery mode (P = .006), insurance type (P less than .001), NICU stay (P less than .001), and gestational age (P less than .0001). However, on multivariate logistic regression, only two factors were significantly associated with the diagnosis of AD: race (P less than .0001) and NICU stay (P = .0385).

“When we looked at the early childhood period specifically, we found striking racial differences in the rates of AD arising early in life,” Dr. Monir concluded. “The diagnosis was independently associated with race and NICU stay. We suggest that further investigation into these disparities and ways we can mitigate them should focus on this early childhood period.”

The researchers reported having no relevant financial disclosures.

However, on multivariate logistic regression, only two factors were significantly associated with the diagnosis of AD: race (P less than .0001) and NICU stay (P = .0385).

“When we looked at the early childhood period specifically, we found striking racial differences in the rates of AD arising early in life,” Dr. Monir concluded. “The diagnosis was independently associated with race and NICU stay. We suggest that further investigation into these disparities and ways we can mitigate them should focus on this early childhood period.”

Contact dermatitis is an eczematous, pruritic eruption caused by direct contact with a substance and an irritant or allergic reaction. While it may not be contagious or life-threatening, contact dermatitis may be tremendously uncomfortable and impactful. Contact dermatitis may occur from exposure to chemicals in soaps, shampoos, cosmetics, metals, plants and topical products, and medications. The hallmark of contact dermatitis is localized eczematous reactions on the portion of the body that has been directly exposed to the reaction-causing substance. Signs and symptoms of contact dermatitis include significant pruritus and acute eczematous changes, including vesicles and papules – often with oozing and crusting.

Irritant contact dermatitis is the most common type, which occurs when a substance damages the skin’s outer protective layer and does not require prior exposure or sensitization. Allergic contact dermatitis (ACD) can develop after exposure and sensitization, with an external allergen triggering an acute inflammatory response.¹ Common causes of ACD include nickel, cobalt, gold, chromium, poison ivy/oak/sumac, cosmetics/personal care products that contain formaldehyde, fragrances, topical medications (anesthetics, antibiotics, corticosteroids), baby wipes, sunscreens, latex materials, protective equipment, soap/cleansers, resins, and acrylics. Among children, nickel sulfate, ammonium persulfate, gold sodium thiosulfate, thimerosal, and toluene-2,5-diamine are the most common sensitizers. Rarely, ACD can be triggered by something that enters the body through foods, flavorings, medicine, or medical or dental procedures (systemic contact dermatitis).

An Id reaction, or autoeczematization, is a generalized acute cutaneous reaction to a variety of stimuli, including infectious and inflammatory skin conditions such as contact dermatitis, stasis dermatitis, or other eczematous dermatitis.³ Id reactions usually are preceded by a preexisting dermatitis. Lesions are, by definition, at a site distant from the primary infection or dermatitis. They often are distributed symmetrically. Papular or papular-vesicular lesions of the extremities and or trunk are common in children.

Our patient had evidence of a localized periocular contact dermatitis reaction that preceded the symmetric papular, eczematous eruption consistent with an id reaction. Our patient was prescribed hydrocortisone 2.5 % ointment for the eyes and triamcinolone 0.1% ointment for the rash on the body, which resulted in significant improvement.

Rosacea is a chronic and relapsing inflammatory skin disorder that primarily involves the central face. Common clinical features include facial erythema, telangiectasias, and inflammatory papules or pustules. Ocular involvement may occur in the presence or absence of cutaneous manifestations. Patients may report the presence of ocular foreign body sensation, burning, photophobia, blurred vision, redness, and tearing. Ocular disease is usually bilateral and is not proportional to the severity of the skin disease.⁴ Common skin findings are blepharitis, lid margin telangiectasia, tear abnormalities, meibomian gland inflammation, frequent chalazion, bilateral hordeolum, conjunctivitis, and, rarely, corneal ulcers and vascularization. Our patient initially did have bilateral hordeolum in what may seem to be ocular rosacea. However, given the use of a recent topical antibiotic with subsequent eczematous rash of the eyelids and then resulting distant rash on the body 1week later made the rash likely allergic contact dermatitis with id reaction.

Seborrheic dermatitis is a chronic, relapsing, and usually mild form of dermatitis that occurs in infants and in adults. The severity may vary from minimal, asymptomatic scaliness of the scalp (dandruff) to more widespread involvement. It is usually characterized by well-demarcated, erythematous plaques with greasy-looking, yellowish scales distributed on areas rich in sebaceous glands, such as the scalp, the external ear, the center of the face, the upper part of the trunk, and the intertriginous areas.

Psoriasis typically affects the outside of the elbows, knees, or scalp, although it can appear on any location. It tends to go through cycles, flaring for a few weeks or months, then subsiding for a while or going into remission. Ocular involvement is a well known manifestation of psoriasis.⁵ Psoriatic lesions of the eyelid are rare, even in the erythrodermic variant of the disease. Occasionally, pustular psoriasis may involve the eyelids, with typical psoriatic lesions visible on the skin and lid margin. The reason for the relative sparing of the eyelid skin in patients with psoriasis is unknown. Other manifestations include meibomian gland dysfunction, decreased tear film break-up time, a nonspecific conjunctivitis, and corneal disease secondary to lid disease such as trichiasis.

Gianotti-Crosti syndrome (GCS), also known as papular acrodermatitis, papular acrodermatitis of childhood, and infantile papular acrodermatitis, is a self-limited skin disorder that most often occurs in young children. Viral infections are common GCS precipitating factors . GCS typically manifests as a symmetric, papular eruption, often with larger (3- to 10-mm) flat topped papulovesicles. Classic sites of involvement include the cheeks, buttocks, and extensor surfaces of the forearms and legs. GCS may be pruritic or asymptomatic, and papules typically resolve spontaneously within 2 months. Occasionally, GCS persists for longer periods. The eyelid lesions and localized pattern, with the absence of larger symmetric papules of the buttocks and legs, was not consistent with papular acrodermatitis of childhood.

Exam and biopsy led to a diagnosis of erythema dyschromicum perstans. Notably, the punch biopsy was performed as superficially as possible to avoid injuring the marginal mandibular branch of the facial nerve. Histology showed focal vacuolar interface changes, pigmentary incontinence, and prominent dermal melanophages—consistent with erythema dyschromicum perstans.

Erythema dyschromicum perstans is an uncommon dermal macular hyperpigmentation that can affect patients of all ages. It is more often seen in patients with Fitzpatrick skin types III and IV. Some patients have a preceding inflammatory phase with associated erythema.

It is believed that erythema dyschromicum perstans may be a form of pigmented lichen planus with similar histologic changes. Genetic predisposition and medications, such as penicillamine and omeprazole, have been suggested as predisposing risk factors, although these risk factors are not always present. Similarly, cases of erythema dyschromicum perstans associated with human immunodeficiency virus and hepatitis C virus have been reported, but a causal link has not been established. Commonly affected sites include the face and neck, although patches on the trunk and extremities occur, as well.

The differential diagnosis includes lichen planus, discoid lupus, drug-induced hyperpigmentation, Hansen disease, and fixed drug eruption.

Erythema dyschromicum perstans is resistant to most therapies, yet it may clear spontaneously over the years. Therapies that have been successful in case reports include Q-switched ruby laser, topical steroids, UV therapy, isotretinoin, and clofazimine. This patient used desonide cream 0.05% bid for 3 weeks without improvement. She then used camouflage concealer for a year, at which point the area had faded almost completely.

Be wary of “for eczema” advertising claims contained on the labels of popular skin moisturizers.

Results from a study presented during the virtual annual meeting of the Society for Pediatric Dermatology found that 93% of the top 30–selling skin products for eczema contained at least one common allergen.

“Prescription medications are important for managing eczema flares, but a lot of the work in treating eczema is preventative, done by consistently moisturizing the skin at home with drug store products,” co-first study author Catherine L. Ludwig, said in an interview. “Allergic contact dermatitis occurs more commonly in people with eczema. A previous study was done in characterizing the allergenic potential of drug store moisturizers and found that 88% of moisturizers contain at least one common allergen. Many moisturizers are marketed specifically to eczema, but the allergen content of these products are unknown.”

For the current study, Ms. Ludwig, a medical student at the University of Illinois at Chicago and co-first author Alyssa M. Thompson, a medical student at the University of Arizona, Tucson, and their colleagues compiled a list of the top 30 moisturizers “for eczema” sold by Amazon, Target, and Walmart. For each moisturizer they recorded common ingredients and marketing claims related to benefits for atopic dermatitis, including eczema relief, sensitive/gentle skin, hypoallergenic, anti-itch, anti-inflammatory, clinically proven, oatmeal, dermatologist recommended/approved, organic, fragrance-free, for baby, or National Eczema Association approved. To establish allergenic potential, the researchers used MATLAB to compare ingredient lists to compounds listed as common allergens in the American Contact Dermatitis Society’s Contact Allergen Management Program database (ACDS CAMP). Next, they used the Mann-Whitney U test to evaluate differences in allergen count between products with and without specific marketing claims.

Ms. Ludwig and her associates found that 28 of 30 products analyzed (93%) contained at least one allergen, with an overall average allergen count of 3.60. The three most prevalent allergens were cetyl alcohol (70%), phenoxyethanol (50%), and aloe (33%). “Anti-inflammatory” moisturizers had the greatest average number of allergens (4.00), followed by “anti-itch” (3.71) and “oatmeal” (3.71). Only products claiming to be “hypoallergenic” had significantly lower allergenic ingredient count (an average of 2.45) than those without the claim (P = .011).

“It was validating to see that eczema moisturizer products marketed as ‘hypoallergenic’ truly do have fewer allergenic ingredients than moisturizers without the claim,” Ms. Ludwig said. “However, it was surprising to see that even products marketed to eczema patients, who have a higher prevalence of allergic contact dermatitis, contain an average of 3.6 common allergens. As dermatology providers, we can relay to patients and parents that relying solely on ‘for eczema’ claims is not advisable. Clinicians should acquaint themselves with the top allergens (cetyl alcohol, phenoxyethanol, and aloe) and keep these ingredients, as well as affordability and patient preferences, in mind when making product recommendations.”

Shi, MD, is a stock shareholder of Learn Health and has served as an advisory board member and/or investigator, and/or received research funding from AbbVie, Burt’s Bees, GpSkin, LEO Pharma, Eli Lilly, Menlo Therapeutics, Novartis, Pfizer, Regeneron, Sanofi Genzyme, Skin Actives Scientific, and SUN Pharma, and the Foundation for Atopic Dermatitis, Global Parents for Eczema Research, and the National Eczema Association.

Only products claiming to be “hypoallergenic” had significantly lower allergenic ingredient count (an average of 2.45) than those without the claim (P = .011).

“It was validating to see that eczema moisturizer products marketed as ‘hypoallergenic’ truly do have fewer allergenic ingredients than moisturizers without the claim,” Ms. Ludwig said. “However, it was surprising to see that even products marketed to eczema patients, who have a higher prevalence of allergic contact dermatitis, contain an average of 3.6 common allergens. As dermatology providers, we can relay to patients and parents that relying solely on ‘for eczema’ claims is not advisable. Clinicians should acquaint themselves with the top allergens (cetyl alcohol, phenoxyethanol, and aloe) and keep these ingredients, as well as affordability and patient preferences, in mind when making product recommendations.”

Once-daily topical roflumilast, a potent selective topical phosphodiesterase-4 inhibitor, brought marked improvement in signs and symptoms of chronic plaque psoriasis – including challenging lesions in tough-to-treat intertriginous areas – in a phase 2b, randomized, double-blind, vehicle-controlled clinical trial, Mark G. Lebwohl, MD, reported at the virtual annual meeting of the American Academy of Dermatology.

The clinical improvement occurred rapidly. And topical roflumilast’s side effect profile was essentially the same as in vehicle-treated controls, which suggests a potential major advantage for the novel drug in future clinical practice. After all, topical treatment is the mainstay of psoriasis therapy, but the current topical agents – high-potency corticosteroids, vitamin D derivatives, and retinoids – have long-term tolerability, efficacy, or side effect issues, especially in treating sensitive skin areas, including the face and intertriginous areas.

“Roflumilast cream could really be a game changer,” predicted Dr. Lebwohl, professor and chair of the department of dermatology at the Icahn School of Medicine at Mount Sinai, New York.

Phosphodiesterase-4 (PDE-4) activity is elevated in psoriatic skin. Indeed, inhibition of PDE-4 via oral apremilast (Otezla) is an established strategy for improving psoriasis through down-regulation of inflammatory cytokines including tumor necrosis factor–alpha, interleukins-17 and -23, and interferon-gamma. Notably, however, roflumilast is orders of magnitude more potent than any other PDE-4 inhibitor. An oral version marketed as Daliresp has been available for treatment of chronic obstructive pulmonary disease for nearly a decade.

The 12-week, multicenter, phase 2b study included 331 patients with chronic plaque psoriasis who were randomized to once-daily 0.3% roflumilast cream, 0.15% roflumilast cream, or vehicle. Three-quarters of participants had a baseline Investigator Global Assessment (IGA) score of 3, indicative of moderate disease.

The primary endpoint was achievement of an IGA score of 0 or 1 (clear or almost clear) at week 6. The observed improvement was dose related, although both doses of roflumilast were significantly more effective than vehicle. However, peak improvement occurred at week 8, not week 6, with subsequent plateauing of response through week 12. A week 8 IGA of 0 or 1 plus at least a 2-grade improvement from baseline occurred in 32% of the high-dose roflumilast group, 25% of those on the 0.15% formulation, and 10% of controls.

“The effect in improvement was very rapid, with a statistically significant improvement compared to vehicle for both concentrations as early as week 2,” Dr. Lebwohl said.

A key secondary endpoint focused on treatment response in intertriginous areas, since “those are the areas where we really don’t want to use steroids because of major irritation problems,” the dermatologist explained. At week 12, treatment success as defined by an intertriginous IGA score of 0 or 1 plus at least a 2-point improvement from baseline was seen in 86% of the 0.3% roflumilast cream group, 50% on low-dose therapy, and 29% of controls.

About 65% of subjects on high-dose roflumilast cream reported at least a 4-point reduction in the Worst Itch–Numerical Rating Scale by week 8, as did 58% of those on the low-dose version and 42% of controls. Another secondary endpoint – patient-reported burden of disease as captured in a Psoriasis Symptoms Diary – showed a significant divergence between both doses of roflumilast and vehicle as early as week 2.

“Adverse events were negligible,” Dr. Lebwohl said. “In fact, there was only one discontinuation in the 0.3% arm, compared to none with 0.15% and two with vehicle.”

The phase 3 program is now recruiting participants.

The phase 2b study was funded by Arcutis Biotherapeutics. Dr. Lebwohl reported receiving research funding from and serving as a consultant to that company and numerous others.
