Pigmented basal cell carcinoma: Cytological diagnosis and differential diagnoses

Abstract

Pigmented basal cell carcinoma is a rare cutaneous neoplasm with only a few cases reported so far. Review of the literature yielded only an occasional fine-needle aspiration report of the cytologic features of the tumor.We report a rare case of pigmented basal cell carcinoma occurring on the thigh of a 55-year-old woman. The cytological features are described with discussion over the possible differential diagnoses.
