Disseminated Superficial Actinic Porokeratosis (DSAP) is a non contagious keratinization disorder of the skin that produces scaly and threaded rim-like lesions.  In its early stages this condition may only be identified by a raised white thin border, and visible only at an angle against a bright backdrop. Eventually these lesions will develop into raised spots that turn red according to body temperature and sun exposure. While most research indicates this is a rare condition, there is speculation the condition is not as rare as once thought.
