Sebaceous neoplasms associated with visceral carcinomas.

Two patients with sebaceous neoplasms and visceral carcinomas (Torre's syndrome) exemplified features noted but not emphasized by authors of the 11 previously reported cases: family history of carcinoma, internal carcinomas of low-grade malignancy, and concomitant colonic polyposis and keratoacanthomas. Five other cases previously reported appear to represent this syndrome. The cutaneous neoplasms may be important markers for visceral carcinomas in such patients and in family members.
