Diagnostic dilemma in pigmented basal cell carcinoma: A case report.

Basal cell carcinoma (BCC) is the most common malignant skin tumor, constituting 80% of nonmelanocytic skin tumors. Intermittent exposure to ultraviolet radiation is considered a major risk factor for BCC. This study was done in 2023 at a tertiary care cancer centre in North India. Pigmented BCC is a rare entity, a histopathological and clinical variant of BCC. This entity belongs to the category of nonmelanocytic skin tumors but exhibits increased pigmentation. Increased pigmentation also creates suspicion of melanocytic tumors, seborrheic keratosis, and Discoid Lupus Erythematosus DLE. However, this diagnostic dilemma can be elicited with histopathological analysis and clinical correlation. However, to prevent basal cell carcinoma, the best is to avoid direct sunlight; if it cannot be avoided, use sunscreen.
