Eosinophilic Pustulosis: A Case Report

Abstract

A 16-year-old female had a chronic cutaneous eruption clinically characterized by papules, pustules and large exudating plaques of 2 years duration. Multiple biopsies showed infiltration of the follicular epithelium by eosinophils and intraepidermal pustules with neutrophils and eosinophils that were accompanied either by acantholysis or spongiosis. Eosinophilia and hypoproteinemia were detected. A definite infectious etiology or autoimmune mechanism could not be established. Differential diagnosis with other entities that share some clinico-pathological and immunological features are discussed.
