The face is a common site for squamous cell carcinoma. It often appears on sun-exposed areas of the body, but can appear elsewhere. In this example, this raised lesion has crusty areas that are considered to be abnormal. If you have any spots, lumps, or bumps that are scaly, ulcerated, or simply do not heal or come back after healing, see a dermatologist.
