Eosinophilic Pustular Folliculitis in Children after Stem Cell Transplantation: An Eruption Distinct from Graft-Versus-Host Disease.

Eosinophilic pustular folliculitis ( EPF) is a rare cutaneous disorder that typically occurs in three clinical contexts: men, individuals who are immunosuppressed or have human immunodeficiency virus, and infants. A fourth subtype occurring 2 to 3 months after hematopoietic stem cell transplantation ( HSCT) has recently been described in several adults. We report two cases of EPF arising in children after HSCT. It is important to recognize this form of EPF after HSCT and differentiate it from graft-versus-host disease since it responds readily to topical steroids and appears to have an excellent prognosis.
