The clot sections consist mostly of erythrocytes and fibrin. A few cellular marrow particles are seen. A small lymphoid infiltrate is identified in this material. The overall features are histologically similar to the core biopsy. The smears are hypocellular and unsuitable for formal cell count.
Maturation is orderly in both cell lines.
Both cell lines show mild megaloblastoid nuclear changes. Scattered small lymphocytes are seen. An iron stain performed on the aspirate reveals increased reticuloendothelial iron. Sideroblastic iron is slightly decreased. Sideroblastic iron granules present are somewhat coarse.
