Basaloid and lobulated: Sebaceous adenoma.

Abstract

Epithelial membrane antigen (EMA) and non-reactive for Carcino-embryonic antigen (CEA). Basaloid cells of sebaceous neoplasm are immune reactive for cytokeratin 7. Sebaceous adenoma requires distinction from sebaceous hyperplasia, sebaceous carcinoma, disorders with sebaceous differentiation, clear cell variations of eccrine, melanocytic, keratinocytic and xanthomatous conditions. Sebaceous adenoma is adequately managed by a comprehensive surgical excision with consequent minimal tumour reoccurrence.
