Abstract
Chronic basophilic leukemia is a rare and poorly characterized entity. Only a limited number of cases have been described. Herein, we report a patient who presented with fatigue, weight loss, leukocytosis, persistent prominent basophilia, and mild eosinophilia. The bone marrow showed features characteristic of a myeloproliferative neoplasm with a marked increase in maturing basophils. The basophils exhibited nuclear hypersegmentation, abnormal granulation, and abnormally low CD38 expression. Conventional karyotyping revealed a t(5;12)(q31;p13). ETV6 but not PDGFRB rearrangement was detected by fluorescence in situ hybridization.
