  2. Monoclonal gammopathy - Wikipedia

    en.wikipedia.org/wiki/Monoclonal_gammopathy

    Monoclonal gammopathy, also known as paraproteinemia, is the presence of excessive amounts of myeloma protein or monoclonal gamma globulin in the blood. It is usually due to an underlying immunoproliferative disorder or hematologic neoplasms, especially multiple myeloma. It is sometimes considered equivalent to plasma cell dyscrasia.

  3. Monoclonal gammopathy of undetermined significance - Wikipedia

    en.wikipedia.org/wiki/Monoclonal_gammopathy_of...

    Monoclonal gammopathy of undetermined significance (MGUS) is a plasma cell dyscrasia in which plasma cells or other types of antibody-producing cells secrete a myeloma protein, i.e. an abnormal antibody, into the blood; this abnormal protein is usually found during standard laboratory blood or urine tests.

  4. Plasma cell dyscrasias - Wikipedia

    en.wikipedia.org/wiki/Plasma_cell_dyscrasias

    The monoclonal protein in POEMS patients is typically identified as IgA or IgG which in >95% of cases contains a λ chain that is restricted to either of two members of the V lambda 1 subfamily viz., IGLV1-40*01 and IGLV1-44*01 (there are 29 other members in the V lambda family). That is, the myeloma protein in POEMS is almost invariably a ...

    Serum protein electrophoresis showing a paraprotein (spike/peak in the gamma zone) in a patient with multiple myeloma.. A myeloma protein is an abnormal antibody (immunoglobulin) or (more often) a fragment thereof, such as an immunoglobulin light chain, that is produced in excess by an abnormal monoclonal proliferation of plasma cells, typically in multiple myeloma or Monoclonal gammopathy of ...

  6. The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3). ICD-10 includes a list of ...

  7. POEMS syndrome - Wikipedia

    en.wikipedia.org/wiki/POEMS_syndrome

    Plasma cell dyscrasias are a group of monoclonal gammopathies in which normal plasma cells in the bone marrow and soft tissues become altered. POEMS syndrome is often associated with an IgA or IgG lambda limited plasma cell dysfunction. On iliac crest biopsies, patients with POEMS syndrome often have few monoclonal plasma cells.

  8. Heavy chain disease - Wikipedia

    en.wikipedia.org/wiki/Heavy_chain_disease

    Heavy chain disease is a form of paraproteinemia and plasma cell dyscrasia that involves the proliferation of cells producing immunoglobulin heavy chains. [1]This disease is characterized by an excessive production of heavy chains that are short and truncated.

  9. Smouldering myeloma - Wikipedia

    en.wikipedia.org/wiki/Smouldering_myeloma

    Smouldering myeloma is a disease classified as intermediate in a spectrum of step-wise progressive diseases termed plasma cell dyscrasias.In this spectrum of diseases, a clone of plasma cells secreting monoclonal paraprotein (also termed myeloma protein or M protein) causes the relatively benign disease of monoclonal gammopathy of undetermined significance.
