Overview
Plasma cell disorders are a diverse type of blood disorders characterized by the presence of a monoclonal paraprotein in the serum or urine. Monoclonal plasma cells are present in the bone marrow or, rarely, in other tissues. Plasma cell disorders include monoclonal gammopathy of undetermined significance (MGUS), multiple myeloma (MM), lymphoplasmacytic lymphoma/ Waldenstrom macroglobulinemia (LPL/WM), lymphoproliferative disorders, smoldering multiple myeloma (SMM); solitary or extramedullary plasmacytoma, amyloidosis, and POEMS syndrome (Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal protein, and Skin changes).The plasma-cell disorders are characterized by the proliferation of a single clone of plasma cells that produces a homogeneous monoclonal (M) protein. these disorders have been defined by the International Myeloma Working Group.1 In 2006.
Classification
Monoclonal gammopathies of undetermined significance (MGUS)
- Benign (IgG, IgA, IgD, IgM, and, rarely, free light chains)
- Associated neoplasms or other diseases not known to produce monoclonal proteins
- Biclonal and triclonal gammopathies
- Idiopathic (Bence Jones proteinuria)
Malignant monoclonal gammopathies
- Multiple myeloma (IgG, IgA, IgD, IgE, and free light chains)
- Symptomatic multiple myeloma
- Smoldering multiple myeloma
- Plasma-cell leukemia
- Non-secretory myeloma
- IgD myeloma
- POEMS syndrome: polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, skin changes (osteosclerotic myeloma)
- Solitary plasmacytoma of bone
- Extramedullary plasmacytoma
- Malignant lymphoproliferative disorders
Chronic lymphocytic leukemia
Heavy-chain diseases (HCDs)
- γHCD
- αHCD
- μHCD
