A histochemical and immunohistochemical study of extra-ocular sebaceous carcinoma.

Abstract
A histochemical and immunohistochemical study of five cases of extra-ocular sebaceous carcinoma was performed using formalin-fixed and paraffin-embedded tissue specimens. Histochemically, the clear cells of sebaceous carcinomas were negative with periodic acid-Schiff and alcian blue staining. Immunohistochemically, the tumour cells of sebaceous carcinomas showed positive reactions for epithelial membrane antigen, human milk fat globules subclass 1, human milk fat globules subclass 2 and Leu M1, but did not express carcinoembryonic antigen, breast carcinoma associated antigen, S-100 protein, gross cystic disease fluid protein-15 or Dako M1. These histochemical and immunohistochemical findings were compared with those of other skin cancers which must be distinguished histopathologically from sebaceous carcinoma. We conclude that sebaceous carcinoma can be distinguished from eccrine porocarcinoma, malignant clear cell hidradenoma, extramammary Paget's disease, malignant trichilemmoma, squamous cell carcinoma and basal cell carcinoma by histochemical and immunohistochemical techniques using formalin-fixed and paraffin-embedded tissue specimens.
