![]() ![]() The Fitzpatrick skin type is a good predictor of the relative risk of BCC among White race individuals. ![]() A detailed review of the literature with meta-analysis and sensitivity analysis show a significantly higher risk for outdoor workers, with an inverse relationship between occupational UV exposure and BCC risk with latitude. The prime etiological factor in the development of basal cell carcinoma is exposure to UV light, particularly the UVB wavelengths, but UVA wavelengths can also be a factor. Such methods are typically reserved for localized BCC and offer high 5-year cure rates, generally over 95%. The current mainstay of BCC treatment involves surgical modalities such as excision, electrodesiccation and curettage (EDC), cryosurgery, and Mohs micrographic surgery. The majority of BCCs are amelanotic, but variable amounts of melanin may be present within these tumors. ![]() Combinations of these types can occur as well. ![]() More than 26 different subtypes of BCC appear in the literature, but the more common, distinctive, clinicopathologic types include: nodular, micronodular, superficial, morpheaform, infiltrative and fibroepithelial (also known as fibroepithelioma of Pinkus). BCC occurs on the head or neck in the majority of cases, but can involve the trunk and extremities. On clinical examination, BCC usually appears as flesh- or pink-colored, pearly papules with overlying ulceration or telangiectatic vessels. Although rarely fatal, BCC can be highly destructive and disfigure local tissues when treatment is inadequate or delayed. Basal cell carcinoma is usually a slow-growing tumor for which metastases are rare. BCC mostly arises on sun-damaged skin and rarely develops on the mucous membranes or palms and soles. Basal cell carcinoma (BCC), previously known as basal cell epithelioma, is the most common cancer in Humans. ![]()
