Clear-cell basal cell carcinoma of the upper eyelid: a case report.

A clear-cell variant of basal cell carcinoma in a previously unreported site is described. This rare variant appeared on the upper eyelid of an 81-year-old woman. Light microscopic examination showed an intradermal tumor with circumscribed lobules composed of clear cells. Histological differential diagnosis of tumors with clear-cell formation is often confusing and can have a great influence on treatment decision making, including surgical intervention.
