Actinic Keratoses (Skin Patches)
Actinic keratosis are dry, scaly patches that form on sun exposed areas of the skin, including the scalp, face, forearms, and back of the hands. A single lesion is called an “actinic keratosis” or “solar keratosis”. Actinic keratoses are usually scaly, feel like sandpaper to the touch, and range in color from skin-toned to reddish-brown. Actinic keratoses may be as small as the head of a pin or as large as a quarter (or bigger, if left untreated).
