Figure 2 Hemophagocytosis in bone marrow. A: High-power photomicrograph of Diff Quick stain of bone marrow smear showing two large macrophages with foamy cytoplasm within a background of mature erythrocytes. The macrophage on the right has phagocytosed a mature erythrocyte (pink cell with no nucleus, higher arrow) and a nucleated erythrocyte precursor (pink cell with deeply purple nucleus, lower arrow; B: high-power photomicrograph of another large macrophage with foamy cytoplasm containing two phagocytosed nucleated erythrocyte precursor cells (purple nucleus, two arrows).
