Abstract

Chronic myelomonocytic leukemia with eosinophilia is a recently defined rare entity frequently associated with t(5;12)(q33;p13) translocation. It usually shows a peripheral eosinophil count greater than 1500/microL. However, the literature contains a small subset of cases in which the major manifestation is bone marrow eosinophilia. We report a case similar to that subset and discuss our finding that the immature eosinophils are identical to those seen in acute myelomonocytic leukemia with abnormal bone marrow eosinophils.
