The purpose of this review is to provide an overview of the differential diagnosis for eosinophilia, to recommend specific steps for the pathologist evaluating blood and bone marrow, and to emphasize 2 important causes of eosinophilia that require specific ancillary tests for diagnosis: myeloproliferative neoplasm with PDGFRA rearrangement and lymphocyte-variant hypereosinophilic syndrome.

In conclusion, our data provide evidence that imatinib-sensitive PDGFRA point mutations play an important role in the pathogenesis of HES and we propose that more research should be performed to further define the frequency and treatment response of PDGFRA mutations in FIP1L1-PDGFRA-negative HES patients.

Despite patients with FIP1-like-1-platelet-derived growth factor alpha (FIP1L1-PDGFRA) associated HES (myeloid neoplasms associated with PDGFRA rearrangement) have been shown to respond to low-dose imatinib with a complete and durable hematological and cytogenetic remission, influences of imatinib on clinical manifestations related to hypereosinophilia heart involvement are variable.

The pathogenesis of hypereosinophilic syndrome (HES) in some patients is highly dependent on FIP1-Like-1 (FIP1L1)-platelet-derived growth factor receptor alpha (PDGFRalpha), which can generate sustained activation signaling to maintain a cell malignant phenotype.
