Slide show: Sun damage
Previous Next 9 of 10 Actinic keratoses
Actinic keratoses (ak-TIN-ik ker-uh-TOE-seez) appear as rough, scaly raised patches that range in color from almost white to tan to dark pink or brown. Also called solar keratoses, these patches are commonly found on the face, ears, lower arms and hands, and lower legs of light-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.
