IgM multiple myeloma (MM) and Waldenstrom’s macroglobulinemia (WM) are two distinct hematologic entities with the common finding of an IgM monoclonal gammopathy. It is when IgM is identified, along with an involvement of 10 percent or more of LPL cells in the bone marrow, that the disease is referred to as WM. WM is a rare type of blood cancer that involves having abnormal lymphocytes (the main cells of lymphoid tissue) in the bone marrow or in lymph nodes. You may go years without needing further treatment. It occurs in a type of white blood cell called a B-lymphocyte or B-cell, which normally matures into a plasma cell that manufactures immunoglobulins (also called antibodies) to help the body fight infection. 2011 May;86(5):411-6. doi: 10.1002/ajh.22014. The American … Waldenstrom macroglobulinemia cells continue trying to produce antibodies, as healthy white blood cells do, but instead they produce abnormal proteins that the body can't use.
