Bone marrow smear examination at diagnosis. May Grünwald–Giemsa staining, ×400 magnification (upper) and ×1000 magnification (lower). Hyperplasia of erythrocyte series was confirmed and the red arrows were showing megaloblastic change; the ratio of myeloid cells to erythroid cells was found to be markedly decreased to 0.36. The nucleated cell count was 105 × 109/L. The number of megakaryocytes was reduced (0.016 × 109/L) for hyperplastic bone marrow. No feature of malignancy was observed
