Seborrheic Keratoses

These lesions are benign overgrowths of epithelium, largely appearing on the torso, face, and neck. They are seen on almost everyone over the age of 50. The borders are typically irregular, and they range in color from beige or gray-white to very dark brown. These "barnacles" of older skin can number only a few to as many as hundreds. Although often raised and dry, they can be flatter and greasier (seborrheic) in texture.
