What is an actinic keratosis? What causes actinic keratoses?
An actinic keratosis (AK) is a small, rough spot occurring on skin that develops because of chronic sun exposure. Actinic keratoses characteristically appear on photo-damaged skin. Actinic keratosis is also referred to as a solar keratosis.
Specialized forms of actinic keratoses include cutaneous horns, in which the skin protrudes in a thick, hornlike manner, and actinic cheilitis, a scaling and roughness of the lower lip and blurring of the border of the lip and adjacent skin. There are other causes of cutaneous horns, including warts and age spots (seborrheic keratoses).
