Eosinophils and Basophils Carry the Fused BCR/ABL Gene in Chronic Myelogenous Leukemia: Direct Fluorescence in situ Hybridization Analysis on Blood Smears

Four Cases of Chronic Myelogenous Leukemia in Mixed Phenotype Blast Phase at Initial Presentation Mimicking Mixed Phenotype Acute Leukemia with t(9;22)

“…Thus, the BCR-ABL1 fusion gene is expected to be found even in mature neutrophils in CML. In addition, mature eosinophils and basophils carry the BCR-ABL1 fusion gene [11]. …”
