Superficial epithelioma with sebaceous differentiation.

Six cutaneous tumors developed in a 48-year old man, involving his face, right axilla, trunk, and right thigh, during an eight-year period. Biopsy of the lesions demonstrated multiple plate-like lobules of basophilic cells, with broad attachments to the overlying epidermis. Keratin-filled cysts and clusters of sebaceous cells were present within the lobules. None of the tumors have recurred following electrodesiccation and curettage.
