Histopathology

These carcinomas are partially encapsulated and locally invasive with foci of sebaceous lymphadenoma intermixed with or adjacent to regions of pleomor-phic carcinoma cells exhibiting varying degrees of invasiveness. The malignant portion has ranged from sebaceous carcinoma to sheets of poorly differentiated carcinoma, with areas of ductal differentiation, adenoid cystic carcinoma-like areas or foci of epithelial-myoepithelial carcinoma. Perineural invasion, collections of histiocytes and a foreign body giant cell reaction may occur. Cellular atypia is not observed in the sebaceous lymphadenoma portion of the tumour.
