Superficial epithelioma with sebaceous differentiation

Five cases of superficial epithelioma with sebaceous differentiation (SESD) are reported. They occurred as solitary papules on the face of 5 patients, aged 57 to 72. The tumor is characterized by a superficial platelike proliferation of basaloid to squamoid cells with broad attachments to the overlying epidermis. Clusters of mature sebaceous cells are present within the tumors. None of the tumors have recurred or spread following simple excision. SESD is a non‐aggressive tumor of uncertain histogenesis with a tendency toward sebaceous differentiation.
