Actinic or solar keratoses (ker-uh-TOE-sees) appear as rough, scaly raised patches that range in color from flesh colored to dark pink or brown. They're commonly found on the face, ears, lower arms and hands of fair-skinned people whose skin has been damaged by the sun. If left untreated, actinic keratoses may progress to a type of skin cancer known as squamous cell carcinoma.
