title: Multiple squamous cell carcinomas in lesions of discoid lupus erythematosus.
abstract: Squamous cell carcinoma (SCC) is the most common skin cancer in black patients. In half of the cases, it is associated with predisposing factors. We present a patient who has been evaluated for thirty-nine years with a diagnosis of discoid lupus erythematosus (DLE) and has multiple SCCs. The lesions occurred in chronic hyperkeratotic lesions of DLE.
