title: Idiopathic hypereosinophilic syndrome in children: report of a 7-year-old boy with FIP1L1-PDGFRA rearrangement.
abstract: Idiopathic hypereosinophilic syndrome (HES) in children is a very rare disorder; certain clinical differences with adult HES have been described, with no pediatric case with the imatinib-responsive FIP1L1-PDGFRA fusion gene reported to date. The authors describe the clinical course of three children with HES in whom FIP1L1-PDGFRA fusion gene was studied and report the first child with this rearrangement.
