Two Cases of Sebaceous Epithelioma / 대한피부과학회지

ABSTRACT

Sebaceous epithelioma is a rare skin appendage tumor with sebaceous differentiation. It may occur as a primary lesion or may arise within a nevus sebaceus. We present two cases of sebaceous epithelioma developed on the scalp in a 55-year old woman and on the forehead in a 75-year old wornan. Histopathologically the tumors are composed of irregularly shaped cell masses. The majority of cells are undifferentiated basaloid cells, but some cells show differentiation toward sebaceous cells.
