Basal cell epithelioma: an unusual case

A 59-year-old Caucasian male presented with a darkly pigmented inner canthal tumor with a six-month history of rapid growth. Histopathologic examination demonstrated to be a pigmented basal cell epithelioma. While basal cell epitheliomas of the eyelids are common ophthalmic disorders, pigmented lesions are unusual. Pigmented basal cell epitheliomas pose a difficulty in clinical diagnosis because of their resemblance to melanomas and pigmented nevi. The differential diagnosis and treatment of this lesion is reviewed.
