Overview
A bone marrow aspiration is essential in the diagnosis of Waldenström macroglobulinemia.
Bone Marrow Aspirate
A bone marrow aspirate is essential in the diagnosis of Waldenström macroglobulinemia.
Findings suggestive of Waldenström macroglobulinemia include:[1]
- A hypercellular bone marrow aspirate.
- Lymphoplasmacytic infiltrate with characteristic immunophenotype.
Bone Marrow Biopsy
A bone marrow biopsy may be helpful in the diagnosis of Waldenström macroglobulinemia. [1]
Findings on the biopsy suggestive of Waldenström macroglobulinemia include:[1]
- Hypercellular and infiltrated with lymphoid and plasmacytoid cells.
- Dutcher bodies (PAS positive intra-nuclear vacuoles containing IgM monoclonal protein)
- Characteristic feature of Waldenström macroglobulinemia
Three patterns of marrow involvement are described, as follows:
- Lymphoplasmacytoid cells (lymphoplasmacytic and small lymphocytes) in a nodular pattern
- Lymphoplasmacytic cells (small lymphocytes, mature plasma cells, mast cells) in an interstitial/nodular pattern
- A polymorphous infiltrate (small lymphocytes, plasma cells, plasmacytoid cells, immunoblasts with mitotic figures)
