구진성 탄력섬유파괴증 1예: 발진성교원종과의 감별진단

Papular elastorrhexis is a rare entity, possibly a form of connective tissue nevi, characterized by asymptomatic white papules on the trunk and extremities first appearing during childhood or adolescence. Histopathologically, the elastic fibers are decreased and may appear in thin and fragmented forms. This rare condition has clinical and histological findings that overlap with those of other connective tissue nevi, making diagnosis a challenge for dermatologists. Herein we report the case of a 27-year-old Korean female presenting with asymptomatic 2∼5 mm sized whitish papules on both extremities and showing histopathologic findings of increased layers of collagen fibers and decreased and fragmented elastic fibers in the dermis.
