Microscopic findings of the bone marrow smears. Bone marrow aspirate smears (May–Giemsa staining; magnification: ×400) showed (a) myeloblasts (arrows) and a hyposegmented mature neutrophil (arrowhead), (b) a binucleated erythroblast, and (c) a micromegakaryocyte (indicated with a star). (d) Myeloperoxidase staining (magnification: ×400) of the bone marrow cells showed a hypogranular neutrophil (indicated with an asterisk).
