The bone marrow core biopsy H&E stain above shows a hypercellular marrow with 100% cellularity and an increase in granulocyte precursors. In addition, an increase in basophils, eosinophils, and an occasional monocyte and blast are also observed. The arrow points to granulocytes comprising most of the marrow.
