| Abstract: | Superficial epithelioma with sebaceous differentiation developed on the left cheek of a 58-year-old man over a three-year period. Biopsy of the lesion demonstrated plate-like lobules of basophilic basaloid cells with broad attachments to the overlying epidermis. Clusters of or solitary sebaceous cells were present within the lobules. Three tumor types were considered; a subtype of sebaceoma growing in the epidermis, an acanthotic seborrheic keratosis subtype with sebaceous differentiation, or a tumor of the follicular infundibulum with sebaceous differentiation. |
