Squamous cell carcinoma of the lip. View of ulcer- like scabbed growth at the corner of the mouth in a man. This is a squamous cell carcinoma, one of the 3 most common types of skin cancer. Squamous cell carcinoma arises from flattened scale-like cells in the skin, usually in areas that have been overexposed to sunlight. This cancer is most common in pale-skinned, fair-haired people over the age of 60. The tumour starts as a small, firm painless lump that slowly enlarges, often resembling a wart or an ulcer. Treatment includes surgical removal of the tumour or radiotherapy. See photo number M131/241 showing scar after surgical treatment.
