Juvenile subcorneal pustular dermatosis: a case report.

Subcorneal pustular dermatosis is a chronic, relapsing, pustular dermatosis that usually develops in elderly women. It is rarely seen in childhood and adolescence. The hallmark of the disease is formation of a subcorneal pustule detected on histopathologic examination. Herein we present a 13-year-old girl diagnosed with subcorneal pustular dermatosis based on the typical clinical and histologic findings. Direct and indirect immunofluorescence and serum protein electrophoresis had negative results. The patient partially recovered after 5 weeks of treatment consisting of oral dapsone and a topical steroid ointment.
