What Are Sun Spots?

Sun spots, also called solar lentigo, are hyperpigmented, flat, smooth lesions that are seen but cannot be felt. They occasionally resemble moles and are usually light tan to brown in color. Sun spots develop most commonly on Caucasians who are 20 years of age or older and occur on the sun-exposed skin of the face, neck, chest, forearms, and hands. Sun spots should be monitored for changes in growth, color, or surface contour because these changes can be indicative of skin cancer formation.
