Waldenstrom's macroglobulinemia

A rare cancer of the lymph cells that causes the body to produce abnormal levels of plasma cells (plasmacytosis) and lymphocytes (lymphocytosis) in the bone marrow. Waldenstrom's macroglobulinemia may also cause a decrease in the number of red blood cells (anemia) and enlargement of the liver (hepatomegaly), spleen (splenomegaly), or glands (adenopathy).
