Squamous cell cancer: a practical approach.

Cutaneous squamous cell carcinoma (SCC) is the second most common form of skin cancer and is treated frequently by dermatologists. For many years, the level of knowledge regarding treatment of SCC has taken a backseat to the treatment of basal cell carcinoma and malignant melanoma. As dermatologists become more surgically proficient and assume a leading role in the surgical care for cutaneous carcinoma, a thorough knowledge of the appropriate management of SCC is of paramount importance. In particular, it is essential to recognize that, unlike basal cell carcinoma, certain SCC have a significant metastatic potential and require more comprehensive care. This review targets the etiology, pathogenesis, clinical presentation, histopathology, and treatment of SCC. Particular attention is focused on providing appropriate care for SCC and recognizing and arranging appropriate management for high risk SCC.
