Eosinophilic pustular folliculitis in infancy and childhood.

We describe nine patients with eosinophilic pustular folliculitis occurring in infancy. All patients had recurrent crops of pruritic papules primarily affecting the scalp and brow region of the face. Biopsy specimens revealed folliculitis with a predominant eosinophilic infiltrate. Bacterial and fungal cultures of pustules were negative. Most patients had leukocytosis and eosinophilia. Clinical response to topical corticosteroid and/or systemic antibiotic therapy was noted. Eosinophilic pustular folliculitis of infancy must be considered in the differential diagnosis of pustular disorders in infancy.
