What is an actinic keratosis, and what does it look like?

An actinic keratosis (AK) is a small, rough spot occurring on skin that develops because of chronic sun exposure. Actinic keratoses generally range in size between 2-6 mm in diameter (between the size of a pencil point and that of an eraser). They are usually reddish in color, with a rough texture and often have a white or yellowish scale on top. There is often a prickling pain felt when it is touched. Actinic keratosis often occurs against a background of sun damage, including sallowness, wrinkles, and excess superficial blood vessels. 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).
