A Case of Solitary Papular Angiokeratoma with Transepidermal Elimination / 대한피부과학회지

ABSTRACT

Transepidermal elimination is a well known phenomenon describing cases where foreign materials or altered dermal constituents are removed from dermis through epidermis. The phenomenon of transepidermal elimination may occur as a primary process or as a secondary process. A 36-year-old women presented with three black papules on the ventral side of her right second toe for 1 year. Because of poliomyelitis, the lesion had been irritated repeatedly. The histopathology of the lesion showed solitary papular angiokeratoma with transepidermal elimination. In this case, we postulated that transepidermal elimination of this case could have developed through repetitive physical trauma.
