Pigmented squamous cell carcinoma

Pigmented squamous cell carcinomas have been reported in the oral and ocula r mucosae, but rarely in the skin. We present a case of pigmented squamous cell carcinoma of the forehead and review the current English literature. P igmented squamous cell carcinoma can be confused with pigmented basal cell carcinomas and melanoma, especially those melanomas associated with pseudoe pitheliomatous hyperplasia and should be included in the differential diagn osis of atypical pigmented lesions.
