(a) Markedly hypercellular bone marrow with left-shifted granulopoiesis, increased erythropoiesis with prominent erythroid islands, decreased megakaryopoiesis, and prominent hemophagocytosis (bone marrow biopsy, H&E, 200x). (b) Clusters of histiocytes with hemophagocytosis (bone marrow biopsy, H&E, 400x). (c) Bone marrow aspirate was hemodilute; however, it showed focal hemophagocytosis (bone marrow aspirate smear, Wright-Giemsa stain, 1000x).
