Overview
Waldenström's macroglobulinemia must be differentiated from Multiple myeloma, Chronic lymphocytic leukemia/small lymphocytic lymphoma, B-cell prolymphocytic leukemia, Follicular lymphoma, Mantle cell lymphoma, and Marginal zone lymphoma. [1]
Differentiating Waldenström's macroglobulinemia from other B cell lymphoid neoplasms
Waldenström's macroglobulinemia must be differentiated from other B cell lymphoid neoplasms including:[1][2]
- Always express CD5, usually CD23 positive[1]
- Express bright surface IgM, CD20 and other B-cell antigens (CD19, CD22, CD79a, FMC7)
- Express CD10, HLA-DR, pan B-cell antigens (CD19, CD20, CD79a), CD21, and surface IgM, IgG, or IgA
- Bone marrow infiltration of small, cleaved cells that are usually paratrabecular
- Rearrangement of Bcl-2
- Express CD138, CD38, CD79a, and VS38c and CD56(70%)
- Presence of Plasmacytic cell infiltration of bone marrow, osteolytic lesions and renal insufficiency
- Translocation involving chromosome 11 (t11;14)
- Express CD5+ and CD23-, surface IgM and IgD and cyclin D1 in majority of cases
- Infiltration of bone marrow by monomorphous, small lymphoid cells with irregular nuclei
- Marginal zone lymphoma:
- Expresses B cell markers CD19, CD20, and CD22
- Infiltrates the bone marrow with a characteristic intertrabecular and intrasinusoidal pattern
- Most common cytogenetic abnormalities are loss of 7q (19%) along with +3q (19%) and +5q (10% )
