Bone marrow aspirate showing normal "trilineage hematopoiesis": myelomonocytic cells (an eosinophil myelocyte marked), erythroid cells (an orthochromatic erythroblast marked), and megakaryocytic cells.


Microscopic evaluation

  • Confirm trilineage hematopoiesis (see image).
  • Look for apparent cellular atypia or decrease of cellular diversity.


Example in a normal case:

Bone marrow from rib (or other location if applicable): Trilineage hematopoiesis. There is no evidence of malignancy.
