Disseminated superficial actinic porokeratosis: A case report

Abstract

Disseminated superficial actinic porokeratosis (DSAP) is characterized by small, atrophic patches with distinctive keratin rims that occur on sun-exposed areas of the extremities, shoulders, and back. The diagnosis is based on the histopathologic finding of a cornoid lamella, absence of a granular layer, and often a thin epidermis. It is associated with exposure to ultraviolet radiation. We report a case of DSAP in our setting.
