Nevoid basal cell carcinoma syndrome in a person with dark skin.

The expression of basal cell carcinoma tumors of the skin is blunted in individuals with dark skin and nevoid basal cell carcinoma syndrome. The occurrence of multiple basal cell carcinomas in these patients is a relatively rare finding. We describe a 25-year-old man of partial African-American descent with constitutive Fitzpatrick type IV pigmented skin and the clinical stigmata of nevoid basal cell carcinoma syndrome including histopathologic evidence of 11 basal cell carcinomas.
