Morphologic changes of bone marrow smear (WrighteGiemsa, x1000). (A) Initial bone marrow showed slightly hypercellular marrow with marked eosinophil infiltrates; no definite blasts were found in this specimen. (B) Second bone marrow smear revealed multilineage dysplasia and markedly increased abnormal myeloblasts with eosinophils. (C) Third bone marrow smear showed hypercellular, with 80.5% blasts and 1% eosinophils.

Bone marrow (BM) specimen showed a hypercellular marrow with hypereosinophilia (26.0%) (Fig. 1A). The man was again admitted to our clinic because of fatigue and weight loss in August, 2017. The leukocytes was 5.4 x 109/L (26.5% eosinophils), hemoglobin levels was 72 g/L, and the platelets was 187 x 109/L, BM smear showed slightly hypercellular marrow with eosinophilia(11.0%), multilineage dysplasia, and blasts comprised 7.5% of nucleated cells (Fig. 1B). BM was hypercellular, with 80.5% blasts, 1% eosinophils (Fig. 1C).
