Two Cases of Infantile Eosinophilic Pustular Folliculitis / 대한피부과학회지

ABSTRACT

Eosinophilic pustular folliculitis(EPF) is a rare inflammatory follicular disorder of unknown etiology. EPF is characterized by recurrent clusters of pruritic, follicular, sterile papules and pustules on the seborrheic area of young men. Compared with classical adult type, infantile EPF reveals the distinctive clinical features, such as constant involvement of the scalp, self-healing recurrent crops, and the possibility of lasting until 3 years of age. We describe two patients with infantile EPF. Both patients commonly had recurrent crops of papules and pustules affecting the scalp only. Bacterial and fungal cultures were negative, and one patient showed an eosinophilia. Biopsy specimens revealed folliculitis with a predominant eosinophilic infiltrate. Clinical response to oral antihistamines and topical corticosteroids was noted, but the lesions have been recurrent during the long-term follow-up period of 1 year.
