Abstract

Disseminated superficial actinic porokeratosis (DSAP) is a skin condition that usually shows a poor response to different modalities of treatment. Herein we describe 2 patients with DSAP on the face, each treated with 3 to 4 sessions of photodynamic therapy combined with laser vaporization.

  Fig. 1 Dermoscopic findings of a disseminated superficial actinic porokeratosis lesion. The peripheral rim is prominent (A), despite vigorous CO2 laser ablation the rims remain intact (arrows) (B).

  Fig. 2 Initial lesions of disseminated superficial actinic porokeratosis on the face (A), after 3 sessions of methyl aminolevulinate (MAL)-photodynamic therapy (PDT) (B), & diffuse scaling and aggravation of the underlying melasma following MAL-PDT (C). The pigmentation was prominent at her follow-up visit (which occurred 1 week after the MAL-PDT) and it gradually faded with time, lasting for about a month.
