Cutaneous squamous-cell carcinoma (cSCC), also known as squamous-cell carcinoma of the skin or squamous-cell skin cancer, is one of the three principal types of skin cancer, alongside basal-cell carcinoma and melanoma. [10] cSCC typically presents as a hard lump with a scaly surface, though it may also present as an ulcer. [1]

Sometimes small blood vessels (called telangiectasia) can be seen within the tumor. Crusting and bleeding in the center of the tumor frequently develops. It is often mistaken for a sore that does not heal.
These cells form on the surface of the skin, on the lining of hollow organs in the body, and on the lining of the respiratory and digestive tracts. [ 1 ] The squamous-cell carcinomas of different body sites can show differences in their presented symptoms, natural history , prognosis , and response to treatment .
