Disseminated superficial actinic porokeratosis – http://id.who.int/icd/entity/1828294192

This is the most common form of disseminated porokeratosis and is often referred to by the acronym DSAP. The clinical and histological features are essentially the same as seen in disseminated superficial porokeratosis but the distribution is limited to chronically sun-exposed skin, particularly of the lower legs and extensor forearms. It is seen predominantly in individuals with limited protection by epidermal melanin.
