case_images: Bone marrow biopsy (4x magnification).. The bone marrow biopsy at low magnification shows hypercellularity as noted by approximately 90% cellularity.

case_images: An ultrasound of the abdomen showed normal spleen size and echotexture. A bone marrow biopsy and aspirate were performed to reveal a hypercellular bone marrow of approximately 90% cellularity (Figure 1).
case_images: Bone marrow biopsy (20x magnification).. This higher magnification shows numerous erythroid precursors as noted by variable-shaped, mononuclear cells with dense chromatin nuclear staining. These erythroid precursors show leftward-shifted maturation stages.

case_images: FIG2
case_images: The hypercellularity is mostly due to increased erythroid precursors with leftward shifted maturational stage (Figure 2).
