Waldenstrцm macroglobulinemia

Waldenstrцm macroglobulinemia
a plasma cell dyscrasia resembling leukemia, with cells of lymphocytic, plasmacytic, or intermediate morphology, that secrete an IgM M component. There is diffuse infiltration of bone marrow and often the spleen, liver, lymph nodes, or central nervous system (Bing-Neel syndrome). The circulating macroglobulin produces symptoms of hyperviscosity syndrome: weakness, fatigue, bleeding disorders, and visual disturbances; peak incidence is in the sixth and seventh decades.
