case_images: Peripheral blood smear and bone marrow studies. (a) Peripheral blood smear shows severe neutropenia with no neutrophils seen in this field (hematoxylin and eosin stain; x400), (b) bone marrow biopsy with normal cellularity, increased megakaryocytes (blue arrows), and severe decrease in neutrophils (hematoxylin and eosin stain; x400), and (c) bone marrow smear displays severely decreased segmented granulocytes and increased blasts (blue arrows; Wright-Giemsa stain x400).

case_images: On day three, marrow examination was done and reported a 40-60% cellularity with myeloid hypoplasia (myeloid to erythroid precursor ratio of 0.5 : 1) and increased blasts (Figure 1).
