title: Three carcinomas in one eyelid.
abstract: A 90-year-old woman presented with 2 masses on the right lower eyelid. Excisional biopsy revealed 1 lesion to be Merkel cell carcinoma and the other to be invasive squamous cell carcinoma. The patient also had a prior history of basal cell carcinoma in the same eyelid. This case emphasizes the importance of careful pathologic examination of all eyelid lesions regardless of previous history.
