Basal cell carcinoma in a non-sun exposed site: A rare case report

Abstract

Basal cell carcinoma (BCC) is the most common cutaneous malignancy and accounts for approximately 80% of all non-melanoma skin cancers. BCCs develop characteristically on sun-exposed areas, with around 85% of reported cases developing over the head or neck. This carcinoma can arise, in non-sun-exposed areas also, such as the axilla, nipple, and the genital and perianal areas. In India and in black population, basal cell carcinoma is a rare form of cutaneous malignancy. The majority of BCC are treated surgically, with peripheral margins of 2 to 5 mm for low-risk tumours and 5 to 15 mm for high-risk lesions.
