A Case of Eosinophilic Folliculitis after Allogenic Bone Marrow Transplantatino in Acute Myelogenous Leukemia

Eosinophilic folliculitis (EF) is regarded as a variant of eosinophilic pustular folliculitis (EPF), because it has a few distinctive clinical features different from those of EPF. EF is generally associated with systemic disorders, such as acquired immunodeficiency syndrome (AIDS) and hematologic malignancies. We have recently experienced a case of EF occurring in a 40 year-old male patient treated with allogenic bone marrow transplantation (BMT) for acute myelogenous leukemia(AML) and achieved a good clinical outcome after a short course of systemic corticosteroid therapy. The immunologic aberration resulting from systemic diseases may play a role in the development of EF.
