Overview
There is no established system for the classification of lymphoplasmacytic lymphoma. However, according to a devised criteria based upon patient's symptoms, Waldenström's macroglobulinemia can be further classified into smoldering/asymptomatic and symptomatic WM .
Classification
There is no established system for the classification of lymphoplasmacytic lymphoma. However, according to a devised criteria based upon patient's symptoms, Waldenström's macroglobulinemia can be further classified into:[1]
- Symptomatic Waldenstrom macroglobulinemia.
- Asymptomatic/Smoldering Waldenstrom macroglobulinemia (SWM).[2]
