Disseminated superficial actinic porokeratosis: a case report.

Disseminated superficial actinic porokeratosis (DSAP) is a type of porokeratosis observed in parts of the skin exposed to intense sunlight and usually appears in the third or fourth decade of life. Since it is a rare disorder, herein we present our experience of a 57-year-old man with DSAP. Dermatological examination of the patient revealed pink/red multiple papular lesions, ranging in diameter from 0.5 to 1 cm, with an atrophic center and hyperkeratotic contours limited to sun-exposed skin parts especially in the extremities and rarely in trunk. Cryotherapy was effective in healing the lesions.
