KS, which used to be a rare illness, as it existed only in the classic form, has become more common since the appearance of HIV and, to a lesser extent, of immunosuppressive treatment.

Summary We describe two brothers with eosinophilic pustular folliculitis. Both had recurrent crops of papules and pustules, primarily affecting the scalp. The eruption began in the neonatal period. Both children had a leucocytosis with eosinophilia. Histology revealed folliculitis, with an infiltrate in which eosinophils were predominant. Bacteriological and fungal cultures of pustules were negative. There was a good clinical response to treatment with a topical corticosteroid and dapsone. We review the 28 previously reported cases of eosinophilic pustular folliculitis in infancy. The occurrence of this disorder in brothers suggests that an inherited or contagious factor may be involved in its aetiology.
