Picture of Eosinophilic Pustular Folliculitis

Eosinophilic pustular folliculitis (EPF) is a skin disorder characterized by recurring itchy, red or skin-colored bumps and pustules (bumps containing pus). Skin biopsies of this disorder find eosinophils (a type of immune cell) around hair follicles. The pustules mostly appear on the face, scalp, neck and trunk and may persist for weeks or months. EPF affects males more than females. There are several variants of EPF including classic Eosinophilic pustular folliculitis (mainly occurring in adults in Japan); HIV-associated EPF, also referred to as immunosuppression-associated EPF; and infantile EPF (with onset from birth or within the first year of life).
