Abstract: Introduction: Sebaceous carcinoma is a rare dermatologic tumor affecting the pilosebaceous apparatus of the skin. While the majority of sebaceous carcinomas arise from sebaceous glands in the ocular area, extraocular sebaceous carcinomas, arising from any region populated with sebaceous glands have also been reported. Sebaceous carcinoma can present as a single lesion or in association with secondary malignancies, most commonly with those found in Muir Torre syndrome (MTS), an autosomal dominant condition associated with several types of sebaceous neoplasms as well as a variety of visceral malignancies. The most common form of MTS has been described as a variant of hereditary non polyposis colorectal cancer (Lynch syndrome). Patient profile: Here, we describe the case of a 55-year-old male, with a known history of colorectal cancer, presenting with a rapidly enlarging abdominal wall mass. Interventions and outcomes: Surgical excision of the mass histologically demonstrated sebaceous carcinoma. This diagnosis, the incidental discovery of a papillary thyroid carcinoma and the patient’s history of colorectal cancer, prompted referral for genetic counseling, the results of which are still pending. Discussion: Sebaceous carcinoma is one of several diagnostic criteria of MTS and its presence should prompt a complete evaluation for underlying internal malignancies.
