Resumo
Definição
BCC of the skin is a common neoplasm, related to exposure to sunlight.[1][2][Figure caption and citation for the preceding image starts]: Nodular basal cell carcinoma on the cheek, on background of diffuse solar damage with marked solar elastosisFrom the collection of Prof. Robert A. Schwartz [Citation ends].
BCC can be locally aggressive, but rarely metastasizes. While certain factors can result in higher-grade behavior, in most cases early detection and treatment have made extensive local invasion and destruction from this neoplasm a thing of the past.[3]
