Eosinophilic pustular folliculitis.

Eosinophilic pustular folliculitis is a cutaneous disorder that consists of recurrent crops of pruritic, sterile, papulopustules in a follicular distribution. In pediatric patients, EPF presents primarily in the scalp and is confused with several other more common dermatoses in children. The diagnosis of EPF rests on its inclusion in the differential diagnosis of papulopustular disorders, the recognition of the clinical presentation, and the presence of an eosinophilic infiltrate on biopsy. Treatment with midpotency topical corticosteroids has thus far met with modest success. This is the first report on EPF in the pediatric literature. As pediatricians become more aware of EPF as a distinct clinical entity and as our clinical experience and insight into the pathogenesis of EPF grows, perhaps more effective treatment modalities will be devised.
