Merkel Cell Carcinoma of the Eyelid: a Review
Merkel cell carcinoma (MCC) is a rare, aggressive tumor of both epithelial and neuroendocrine origin that carries a mortality rate of up to 40%. MCC tumors typically present as painless, expanding nodules on the sun-exposed skin areas of older, white patients. Eyelid and periocular tumors comprise approximately 2.5% of all cases of MCC and may be mistaken for chalazia or basal cell carcinomas. Immunosuppression is a significant risk factor, particularly in solid-organ transplant recipients, patients with chronic lymphocytic leukemia, and patients with HIV.
