A Case of Muir-Torre Syndrome

ABSTRACT

PURPOSE: To present a rare case of Muir-Torre syndrome characterized by the association of sebaceous skin tumors and systemic malignancies. CASE SUMMARY: A 65-year-old female visited our clinic with an irregular nodular mass of the right lower eyelid, which developed 1 year earlier. An excisional biopsy and lower lid reconstruction with Tenzel's semicircular rotational flap was performed under local anesthesia. Histopathologic examination showed well-differentiated sebaceous cells, consistent with sebaceous adenoma. The patient had undergone total abdominal hysterectomy and lower anterior resection due to endometrial cancer and sigmoid colon cancer 5 years before, and nephroureterectomy due to papillary urothelial carcinoma 3 years before. Based on the history of systemic malignancy and sebaceous skin cancer, a diagnosis of Muir-Torre syndrome was made. CONCLUSIONS: When a sebaceous gland tumor of the eyelids is detected, Muir-Torre syndrome should be included in the differential diagnosis, and systemic work-up for the internal malignancy must be performed.
