Clinical and pathological presentation of sebaceous carcinoma. a Sebaceous carcinoma with an axis of 4 cm on the top of the head. The tumor was soft and elastic, and the central lesion had an ulcerated surface. b At low magnification with hematoxylin-eosin staining, the sebaceous carcinoma was seen to be present exclusively in subcutaneous tissue and to contain scattered lobular or tubular structures within stromal tissues covered with fibrous capsules. c At high magnification, each lobule consisted of basaloid-like cells and sebocyte-like cells with vacuolated cytoplasm, which were partly necrotized
