Nodular basal cell carcinoma of the scrotum: a case report and review of the literature.

Basal cell carcinoma (BCC) is the most common non-melanoma type of skin cancer described in humans that originates in the epidermis, more specifically in the basal layer and its appendages. Environmental, genetic and phenotypic factors contribute to the onset of this cancer; however, damage caused by ultraviolet radiation from sunlight is the primary risk factor. The emergence of this neoplasm in unexposed body areas, such as the soles, groin, armpit, scrotum or vulva is very rare.
