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 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.
