ABSTRACTDisseminated superficial actinic porokeratosis (DASP) is part of the genodermatosis known as porokeratosis which are of unknown origin and characterized by an anomaly in keratinization. DASP is a generalized process in which sun exposed skin is involved and has the symmetric distribution of the limbs as common trait. It consists of numerous brown-red papules with keratotic rims and central hyperpigmentation, which can grow and become of an annular aspect. Histologically, they are diagnosed by the presence of the “cornoid lamella”. We present a male case 29 years old with disseminated superficial actinic porokeratosis and review literature.
