Editor We have read with great interest Dr Recalcati's review about skin manifestations in COVID-19 as it is the first report on this subject. 1 In a recent review on clinical characteristics of coronavirus disease 2019 in China, rash was observed in 0.2% of cases. 2 However, from the trained eyes of a dermatologist, this percentage may be higher.
Alopecia areata (AA) is a common disease characterized by nonscarring hair loss. There are no satisfactory therapies for extensive cases. Systemic immune suppressants are usually used despite their nonspecific actions and often associated side effects. Apremilast is an oral, small-molecule, inhibitor of phosphodiesterase 4 approved for the treatment of psoriasis and psoriatic arthritis. Its use in AA has shown variable results. Whereas a recent reduced clinical trial concluded a lack of efficacity, several case reports demonstrate a significant improvement. We report four cases of extensive AA successfully treated with apremilast.
Vascular malformations (VM) are congenital, benign, and relatively frequent lesions. Scant data have been published about the epidemiology, clinical presentation, and treatment of VM from a dermatologist's perspective. The substantial differences between subtypes, broad range of specialists consulted and confusing nomenclature used over previous years may hamper a correct diagnosis. The main objective of this study is to describe VM epidemiology. As a secondary endpoint we evaluate clinical characteristics, clinical‐radiological correlation and treatment approaches. We carried out an observational, descriptive, retrospective study. Cases presented to the multidisciplinary committee of our hospital from 2009 to 2019 were retrieved. Electronic medical records, monthly committee reports and the iconographic archive were reviewed and statistically analyzed. Overall, venous malformations (VeM) are the most frequent VM, followed by capillary malformations (CM), arterioVeM and lymphatic malformations (LM). Considering only patients under 16, CMs are the most frequent ones. Capillary and LMs are larger than venous or arteriovenous. While CMs are usually asymptomatic, symptomatic cases are threefold more frequent in the other subtypes. Decisions on active or conservative management depend on VM size but not location or patient age. CMs are mainly treated with laser therapy; venous with sclerotherapy or surgery; arteriovenous with surgery and lymphatic with surgery or sirolimus. Dermatologists play an important role in VM diagnosis and management. Our 10‐year multidisciplinary experience should contribute to the literature and represent a practical resource for clinicians and researchers.
Successful management of toxic epidermal necrolysis (TEN) with tumor necrosis factor‐α inhibitors has been described in adults, but few cases have been reported in children. To date, only four pediatric cases of TEN treated with infliximab and one with etanercept have been published. We present the case of an 8‐year‐old boy diagnosed with TEN induced by levetiracetam, successfully treated with etanercept, systemic corticosteroids, and intravenous immunoglobulin.
Keratoacanthoma centrifugum marginatum (KCM) is a rare variant of keratoacanthoma (KA), characterized by progressive peripheral growth, and usually devoid of deep invasion. Different systemic (oral retinoids) or topical treatments have been reported, but there is not a well‐defined therapeutic protocol. We report the case of a KCM developing after photodynamic therapy (PDT) on the right leg of a 64‐year‐old woman. It was treated successfully with oral acitretin combined with topical 5‐Fluorouracil + salicylic acid for 5 months. This is the first case of KCM developing after PDT and successfully treated with oral retinoid combined with topical treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
