RESUMO
Background@#Lichen striatus (LS) is a linear, inflammatory dermatosis that mainly affects children. To date, there are limited data comparing treatment outcomes between topical agents for pediatric LS. @*Objective@#To investigate the clinical features and treatment outcomes associated with the use of topical agents for pediatric LS. @*Methods@#We retrospectively reviewed the medical records and clinical photographs of 60 pediatric patients classified into three groups according to the topical agent used. Treatment response was evaluated by comparing subjective symptoms and clinical photographs obtained at each visit. @*Results@#A good response (＞75% clinical improvement from baseline) was achieved in 55%, 46.2%, and 42.9% of patients from the calcipotriol, corticosteroid, and calcineurin inhibitor groups, respectively. There were no statistically significant differences in treatment duration among groups. However, when compared to other drugs, calcipotriol showed a trend towards shortening the disease course duration. @*Conclusion@#Topical use of calcipotriol, as well as corticosteroids and calcineurin inhibitors, may represent useful treatment options for pediatric LS, although further studies are required to confirm their efficacy and long-term safety.
RESUMO
BACKGROUND: Psoriasis is a chronic inflammatory disease. In the treatment of psoriasis, cyclosporine is commonly prescribed systemic agents. However, long-term use of cyclosporine is not recommended because of side effects such as nephrotoxicity or hypertension. OBJECTIVE: To ascertain the improved safety of rotational therapy using cyclosporine and methotrexate, we investigated the frequency of abnormal results in laboratory test after long term rotational therapy using cyclosporine and methotrexate. METHODS: From January 2009 to June 2014, patients who were treated with cyclosporine or methotrexate were enrolled. The clinical data and usage of medications were reviewed. Laboratory tests were conducted before starting the treatment and regularly follow-up. The occurrences of any laboratory abnormalities during the treatments were investigated. RESULTS: A total of 21 psoriatic patients were enrolled. The mean of medication period and cumulative dose of cyclosporine and methotrexate were 497.81±512.06 days and 115.68±184.34 g in cyclosporine and 264.19±264.71 days and 448.71±448.63 mg in methotrexate. Laboratory abnormalities were found in total two patients after rotational therapy: two patients (9.5%) in aspartate aminotransferase/alanine aminotransferase and one patient (4.8%) in uric acid. No laboratory abnormalities were found in renal function test. CONCLUSION: We found that the rotational approaches using cyclosporine and methotrexate reduced the possibility of the development of nephrotoxicity. In addition to other advantage such as quick switching from one agent to another, the rotational therapy using cyclosporine and methotrexate can minimize the adverse events during the systemic treatment of chronic plaque psoriasis.

Nail unit melanoma is a type of acral lentiginous melanoma and requires histopathologic examination for a confirmed diagnosis. However, inadequate biopsy techniques make definitive diagnosis difficult. A 61-year-old man presented with progressive nail pigmentation for 15 years, which was clinically highly suspicious for malignancy. Acral lentiginous melanoma was not detected in punch and longitudinal biopsy specimens, but en bloc excision tissue revealed melanoma. Acral lentiginous melanoma is known to have a heterogeneous pathologic manifestation depending on the pigmented region and the time it takes to progress. In this regard, en bloc excision can be considered as a first-line biopsy technique to diagnose acral lentiginous melanoma, indolent subtype.

Morgellons disease is a rare disease with unknown etiology. Herein, we report the first case of Morgellons disease in Korea. A 30-year-old woman presented with a 2-month history of pruritic erythematous patches and erosions on the arms, hands, and chin. She insisted that she had fiber-like materials under her skin, which she had observed through a magnifying device. We performed skin biopsy, and observed a fiber extruding from the dermal side of the specimen. Histopathological examination showed only mild lymphocytic infiltration, and failed to reveal evidence of any microorganism. The polymerase chain reaction for Borrelia burgdorferi was negative in her serum.

BACKGROUND: Allergens tend to sensitize simultaneously. Etiology of this phenomenon has been suggested to be allergen cross-reactivity or concurrent exposure. However, little is known about specific allergen sensitization patterns. OBJECTIVE: To investigate the allergen sensitization characteristics according to gender. METHODS: Multiple allergen simultaneous test (MAST) is widely used as a screening tool for detecting allergen sensitization in dermatologic clinics. We retrospectively reviewed the medical records of patients with MAST results between 2008 and 2014 in our Department of Dermatology. A cluster analysis was performed to elucidate the allergen-specific immunoglobulin (Ig)E cluster pattern. RESULTS: The results of MAST (39 allergen-specific IgEs) from 4,360 cases were analyzed. By cluster analysis, 39items were grouped into 8 clusters. Each cluster had characteristic features. When compared with female, the male group tended to be sensitized more frequently to all tested allergens, except for fungus allergens cluster. CONCLUSION: The cluster and comparative analysis results demonstrate that the allergen sensitization is clustered, manifesting allergen similarity or co-exposure. Only the fungus cluster allergens tend to sensitize female group more frequently than male group.

RESUMO
Sebaceoma, also known as sebaceous epithelioma, is a rare, benign, adnexal tumor with sebaceous differentiation. It usually appears as a yellowish papule, nodule, or plaque on the scalp and face, on which there are abundant sebaceous glands. Histologically, it is a well-circumscribed lesion composed of undifferentiated basaloid cells and mature sebaceous cells in relatively preserved lobulated architectures. A 31-year-old woman presented with a 1.3-cm ×1.1-cm nodule on the right earlobe. Mohs micrographic surgery was performed to completely remove it. Histopathological examination revealed that mature sebaceous cells with scalloped nuclei and focal cystic change were present in the lobule.

Venous leg ulcers, the most common form of leg ulcers, are relevant to the pathogenicity of pericapillary fibrin cuff. Sarcoidosis, a multiorgan granulomatous disease, causes fibrin deposition in tissues. We report a case of a 50-year-old man with venous leg ulcers coexisting with sarcoidosis. On the basis of the histologic findings, we propose the hypothesis that sarcoidosis patients are prone to the development of venous leg ulcers.
