Overview
The diagnosis of lymphoplasmacytic lymphoma is based on bone marrow aspiration and biopsy and serum protein analysis studies such as immunohistochemistry, flow cytometry and cytogenetics to distinguish LPL from other types of B-cell lymphomas. CSF flow cytometry, protein electrophoresis and immunofixation is done for the diagnosis of Bing-Neel syndrome (a late, but severe, rare complication).
Diagnostic Study of Choice
- There is no single diagnostic study of choice for the diagnosis of lymphoplasmacytic lymphoma (LPL), but bone marrow aspiration and biopsy is considered to be mandatory for the assessment of patients with LPL and further supported by monoclonal protein/immunophenotypic studies such as immunohistochemistry, flow cytometry and cytogenetics to distinguish LPL from other types of B-cell lymphomas.[1][2]
- Not all the diagnostic tests mentioned are performed in a patient with lymphoplasmacytic lymphoma. A doctor takes into account the following factors before choosing diagnostic tests in a particular patient:
Diagnostic Criteria:
Diagnostic criteria presented in second International Workshop, Greece, 2002
- In September 26-30, 2002, in Athens, Greece,the Second International Workshop was held in which a diagnostic criteria for Waldenstrom's Macroglobulinemia was proposed. According to this criteria, the following findings on performing bone marrow biopsy and serum protein analysis are confirmatory of Waldenström macroglobulinemia and exclude other small B cell lymphoid neoplasms with plasmacytic differentiation:[1]
mSMART guidelines for diagnosis of Waldenstrom macroglobulinemia and associated disorders
- Mayo Stratification of Macroglobulinemia and Risk-Adapted Therapy (mSMART) Guidelines 2016 for diagnosis of Waldenstrom macroglobulinemia and associated disorders are as follows:[3]
Definitive Diagnostic Tests
- Genetic Testing:
- ARIDA
- IG gene rearrangement
- CXCR4 5338X
- MYD88 L265P
- Immunophenotyping
- Serum paraprotein
Bone Marrow Aspirate:
- A bone marrow aspirate is essential in the diagnosis of lymphoplasmacytic lymphoma
- Findings suggestive of lymphoplasmacytic lymphoma include:[4]
- Hypercellular bone marrow aspirate
- Lymphoplasmacytic infiltrate with characteristic immunophenotype
 |
Bone Marrow Biopsy:
- A bone marrow biopsy may be helpful in the diagnosis of lymphoplasmacytic lymphoma [4]
- Findings on the biopsy suggestive of lymphoplasmacytic lymphoma include:[4]
- Hypercellular and infiltrated with lymphoid and plasmacytoid cells
- Dutcher bodies (PAS positive intra-nuclear vacuoles containing IgM monoclonal protein)
- 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)
Electrophoresis and Immunofixation
- Serum protein electrophoresis is important for the diagnosis of lymphoplasmacytic lymphoma
- Findings on an electrophoresis diagnostic of lymphoplasmacytic lymphoma include:[5]
- Sharp, narrow spike of monoclonal IgM protein
- Dense band of monoclonal IgM protein
- The paraprotein can be of any size
- Serum immunofixation is important for the diagnosis of lymphoplasmacytic lymphoma. It helps in confirming the presence of a monoclonal protein, in addition to determining its type[5]

CSF flow cytometry, protein electrophoresis and immunofixation for diagnosis of Bing-Neel syndrome:
- For diagnosing Bing-Neel syndrome, after lumbar puncture, CSF flow cytometry is done which shows a lambda light chain-restricted population of B-cells consistent with a CD5+ CD10+ B-cell lymphoma
- Furthermore, protein electrophoresis and immunofixation should be done for the detection and classification of a monoclonal protein as well as molecular diagnostic testing for immunoglobulin gene rearrangement and mutated MYD88[6][7][8]
