Large platelets are seen. A core biopsy and clot section are available for review. A mixed population of erythroid, granulocytic, and megakaryocytic elements is present. All cell lines show orderly maturation. Nodular, non-paratrabecular lymphoid aggregates are present.
Lymphocytes are small with round nuclear contour and clumped chromatin.
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.
