치유된 소아황색육아종 부위에 발생한 반상피부위축증 = Secondary Anetoderma Developed in Juvenile Xanthogranuloma

다국어 초록 (Multilingual Abstract)

Anetoderma is characterized by a loss of normal elastic tissue, and is clinically presented as atrophic patches located mainly on the upper trunk. It may be primary or secondary, occurring in the course of various dermatoses. The most common diseases among them are acne and varicella, but there are several reports about other skin diseases causing anetoderma. A 16-year-old girl visited our clinic for the evaluation of asymptomatic atrophic macules on the head, upper trunk and lower extremities. She had a 10-month history of yellowish brown papules located on the same area fifteen years ago. Histopathologic findings at that time showed histiocytic infiltration with foam cells and Touton giant cells in the dermis, which were consistent with juvenile xanthogranuloma (JXG). Skin biopsy was carried out at an atrophic macule; histologic findings revealed a decrease in dermal elastic fibers. All these findings were compatible with anetoderma. To our knowledge, this case is the first report of anetoderma developed in JXG in Korea. (Korean J Dermatol 2013;51(10):829∼832)
