Poorly differentiated squamous cell carcinoma arising within a lesion of discoid lupus erythematosus in an African-American woman

The incidence of skin cancer is rare in African Americans; however, there are several reports of patients with depigmented or hypopigmented lesions on sun-exposed areas, such as the scalp, who are at increased risk for squamous cell carcinoma (SCC). Decrease in melanin, immunosuppressive therapy, frequent ultraviolet exposure, human papillomavirus infection, chronic scarring, and inflammatory processes are factors associated with the development of SCC in black patients.1 We present a rare case of a 55-year-old African-American woman who had SCC within a discoid lupus erythematosus (DLE) lesion.
