Pigmented SCC is an uncommon variant of squamous cell carcinoma of the skin, with an incidence rate of 0.01 to 7% of all squamous cell carcinomas. Here we report a case of pigmented SCC of left cheek in a 90 year old Iranian man. Clinically it was presented as a dome shaped 1 × 1.2 cm blue black nodule with well-defined margin on his left cheek since 2 months ago. Microscopic examination revealed squamous cell carcinoma but melanin pigments were detected in the cytoplasm of some tumor cells that was compatible with the diagnosis of pigmented SCC. The patient underwent complete excision of lesion. The authors believe this the first case of pigmented squamous cell carcinoma of skin in an Iranian patient.
