Erosive pustular dermatosis of the scalp: a review with a focus on dapsone therapy.


PMID 22074698

Abstract

Erosive pustular dermatosis of the scalp (EPDS) is an inflammatory disorder of unknown origin characterized by pustules, erosions, and crusting in areas of alopecia that tend to be atrophic, actinically damaged, or both. The most common treatments reported include antibiotics and topical anti-inflammatories, which can be ineffective. In the search for effective treatment for EPDS, we share our experience with topical dapsone 5% gel. We present 4 patients with EPDS, all with classic clinical presentations and histologic findings of EPDS, who had failed a variety of treatments including oral, intralesional, or topical steroids, tacrolimus, and antibiotics. All patients demonstrated rapid improvement or resolution with topical dapsone 5% gel. Our experience and success with topical dapsone for EPDS is observational and not the result of a randomized controlled trial. Our observations demonstrate topical dapsone 5% gel to be a novel, safe, and efficacious therapeutic alternative for mild to moderate EPDS.
