Muir-Torre Syndrome in a Middle-Aged Chinese Patient with Sebaceous Carcinoma of the Eyelid

Muir-Torre syndrome is a rare, autosomal dominant condition characterized by the presence of a skin tumor of sebaceous differentiation and visceral malignancies. We reviewed the case of a 46-year-old Chinese man who had a bleeding mass over the right upper eyelid. He had a history of colon cancer and a family history satisfying the Amsterdam criteria for hereditary non-polyposis colorectal cancer syndrome with germline mutation in the MutS homolog-2 gene. The eyelid lesion was excised completely and submitted for histopathologic examination which showed sebaceous carcinoma. Frozen section and conjunctival map biopsy showed no residual malignancy or local metastasis. Post-operative positron-emission tomography with combined computed tomography did not reveal any residual or visceral malignancy. He had no recurrence in the 32-month follow-up period. We should consider Muir-Torre syndrome in patients with sebaceous carcinoma, especially in the presence of personal and/or family history of visceral malignancies.
