A 79-year-old man with no history of previous irradiation presented with a large ulcerated tumour of the cheek. The histological features favoured a true sebaceous carcinoma. Neither squamous nor basal differentiation were seen. Sudan stainings were positive. Tumour cells expressed suprabasal keratins and were negative for carcinoembryonic antigen, vimentin and S 100 protein. Extraocular sebaceous carcinomas occurring without previous irradiation are rare tumours which behave aggressively. Treatment regimens are discussed.
