PY - 2016 T2 - Harrison's Manual of Oncology, 2e AB - Plasma cell disorders are a group of related diseases arising from a common progenitor belonging to the B-cell lineage. They are characterized by the expansion of plasma cells in the bone marrow (BM) and nearly always accompanied by the presence of a monoclonal immunoglobulin (Ig) or Ig fragment in the serum and/or urine of patients (1). Monoclonal gammopathy of undetermined significance (MGUS), multiple myeloma (MM), Waldenstrom's macroglobulinemia (WM), primary amyloidosis, and heavy chain diseases (HCD) all belong to this group of disorders. Dysproteinemias or plasma cell dyscrasias are some of the other terms used to refer to this unique group of disorders.
