[[File:BM DD.png|thumb|750px|none| GC-associated lymphoid clones infiltrating the BM osteoblastic niche exhibit mesenchymal features in common with SLO germinal centers.(A–D) Histological examination of B-cell non-Hodgkin lymphoma (B-NHL) patient specimens. (A) The frequency of para-trabecular/osteoblastic localization of lymphoid malignant clones in 197 cases of B-NHL with bone marrow (BM) infiltration. Lymphoid clones of germinal center (GC)-derivation exhibiting preferential tropism for the BM osteoblastic niche include: follicular lymphoma (FL), T-cell rich histiocyte rich diffuse large B-cell lymphoma (TCRBCL), and diffuse large B-cell lymphoma of GC type (DLBCL-GC). Non-GC-related lymphoid clones include: DLBCL- activated B-cell type (ABC); mantle-cell lymmphoma, (MCL); marginal-zone lymphoma, (MZL); lymphoplasmacytic lymphoma, (LPL). (B) Para-trabecular (left panel) and inter-trabecular (right panel) localization of two representative cases of FL with BM infiltration. The distribution of the lymphomatous infiltrates around bone trabeculae or in the inter-trabecular lacunae is highlighted by CD20 immunostaining (inserts). (C–D) FL lymphoid infiltrates localizing within the osteoblastic niche area (left panels) and inter-trabecular BM (right panels) display a stromal architecture reminiscent of that of secondary lymphoid organ (SLO) GCs and are characterized by the expression of BM-MSC markers SPARC (C) and CD146 (right D).[https://openi.nlm.nih.gov/detailedresult.php?img=PMC4108469_onci-3-e28989-g3&query=waldenstrom+macroglobulinaemia&it=xg&req=4&npos=46 Source: Sangaletti S. et al, Molecular Immunology Unit; Department of Experimental Oncology and Molecular Medicine; Fondazione IRCCS Istituto Nazionale Tumori; Milan, Italy.]]]

Overview

Waldenstrom'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.

Differentiating Lymphoplasmacytic lymphoma from other Diseases

Waldenstrom's macroglobulinemia must be differentiated from following other B cell lymphoid neoplasms:

GC-associated lymphoid clones infiltrating the BM osteoblastic niche exhibit mesenchymal features in common with SLO germinal centers.(A–D) Histological examination of B-cell non-Hodgkin lymphoma (B-NHL) patient specimens. (A) The frequency of para-trabecular/osteoblastic localization of lymphoid malignant clones in 197 cases of B-NHL with bone marrow (BM) infiltration. Lymphoid clones of germinal center (GC)-derivation exhibiting preferential tropism for the BM osteoblastic niche include: follicular lymphoma (FL), T-cell rich histiocyte rich diffuse large B-cell lymphoma (TCRBCL), and diffuse large B-cell lymphoma of GC type (DLBCL-GC). Non-GC-related lymphoid clones include: DLBCL- activated B-cell type (ABC); mantle-cell lymmphoma, (MCL); marginal-zone lymphoma, (MZL); lymphoplasmacytic lymphoma, (LPL). (B) Para-trabecular (left panel) and inter-trabecular (right panel) localization of two representative cases of FL with BM infiltration. The distribution of the lymphomatous infiltrates around bone trabeculae or in the inter-trabecular lacunae is highlighted by CD20 immunostaining (inserts). (C–D) FL lymphoid infiltrates localizing within the osteoblastic niche area (left panels) and inter-trabecular BM (right panels) display a stromal architecture reminiscent of that of secondary lymphoid organ (SLO) GCs and are characterized by the expression of BM-MSC markers SPARC (C) and CD146 (right D).Source: Sangaletti S. et al, Molecular Immunology Unit; Department of Experimental Oncology and Molecular Medicine; Fondazione IRCCS Istituto Nazionale Tumori; Milan, Italy.
