A case of pigmented basal cell carcinoma is reported. A 68-year-old female presented with a black linear plaque on her right axilla for more than 10 years. Physical examination revealed a well defined linear plaque with a size of 3.0 cm × 0.2 cm on her right axilla. There were several grain-sized, black papules scattered on the plaque. Erosion and exudate were noted in the center of the plaque, and inflammatory erythema was seen around the area of exudate. There was no tenderness. Histopathological examination showed nests of tumor cells focally noted in epidermis. There were lobules of atypical cells with basophilic cytoplasm extending from the lower portion of epidermis into dermis. The basaloid lobules showed peripheral palisading with retraction artifacts. Mitoses were present. Diagnosis of pigmented basal cell carcinoma was made.
