Eosinophilic pustule smear in the diagnosis of pediatric post‐transplant eosinophilic folliculitis

Hematologic‐associated eosinophilic pustular folliculitis is a subtype of eosinophilic pustular folliculitis (EPF) which develops in patients with underlying hematological malignancies after treatment with chemotherapy, bone marrow transplant (BMT), or stem cell transplant (SCT). Few cases of hemato...

Description
Summary:Hematologic‐associated eosinophilic pustular folliculitis is a subtype of eosinophilic pustular folliculitis (EPF) which develops in patients with underlying hematological malignancies after treatment with chemotherapy, bone marrow transplant (BMT), or stem cell transplant (SCT). Few cases of hematological‐associated EPF have been reported in pediatric patients. Skin biopsy is considered the gold standard for diagnosis. We describe a case in which Wright staining of a pustule smear for eosinophils provided data to rapidly support a clinical diagnosis of hematologic‐associated EPF.
