The second most common form of nonmelanoma skin cancer is squamous cell carcinoma (SCC) and is responsible for 20% of cutaneous malignancies and 90% of all head and neck cancers. Unlike most basal cell carcinoma, squamous cell carcinoma of the skin are associated with a risk of metastasis. A malignant tumor of epithelial origin, SCC has a regional distribution involved in the biologic activity of the neoplasm. The behavior of SCC depends on its site of origin. Each anatomic site has its own particular spread pattern and prognosis. SCC frequently arises on the sun-exposed skin of middle-aged and elderly individuals.
