Pigmented Basal cell carcinoma: a clinical variant, report of two cases

Abstract

Basal cell carcinoma is the most common malignant tumour of skin, comprising 80% of non-melanoma cancers. Intermittent exposure to ultraviolet radiation is an important risk factor. Pigmented basal cell carcinoma is a clinical and histological variant of basal cell carcinoma that exhibits increased pigmentation. It is a very rare variant, although its frequency can reach upto 6% of total basal cell carcinomas in Hispanics. Herein, we are reporting 2 cases of pigmented basal cell carcinoma.
