Actinic keratosis (solar keratosis) refers to rough, raised, precancerous lesions on the skin that occurs due to excess sun damage. The spots most commonly appear on sun-exposed areas of the face, scalp, back of the hands, feet, and chest. Actinic keratosis sometimes develops into squamous cell skin cancer. The lesions look like flat, scaly areas, often with white or yellow crusty scales. They may start out as pink, red, gray, or skin-toned growths that then develop into hard, wart-like, gritty, or rough spots. Actinic keratosis may be treated with a variety of topical creams or chemical peels. They may also be removed by freezing, scraping, burning, cutting, or laser treatment.
