In hematology, plasma cell dyscrasias (also termed plasma cell disorders and plasma cell proliferative diseases) are a spectrum of progressively more severe monoclonal gammopathies in which a clone or multiple clones of pre-malignant or malignant plasma cells (sometimes in association with lymphoplasmacytoid cells or B lymphocytes) over-produce and secrete into the blood stream a myeloma ...
The first advantage is that the whole-blood platelets, sometimes called "random" platelets, from a single donation are not numerous enough for a dose to give to an adult patient. They must be pooled from several donors to create a single transfusion, and this complicates processing and increases the risk of diseases that can be spread in ...

Multiple myeloma (MM), also known as plasma cell myeloma and simply myeloma, is a cancer of plasma cells, a type of white blood cell that normally produces antibodies. [6] Often, no symptoms are noticed initially. [10] As it progresses, bone pain, anemia, renal insufficiency, and infections may occur. [10]
MPNs arise when precursor cells (blast cells) of the myeloid lineages in the bone marrow develop somatic mutations which cause them to grow abnormally. There is a similar category of disease for the lymphoid lineage, the lymphoproliferative disorders acute lymphoblastic leukemia, lymphomas, chronic lymphocytic leukemia and multiple myeloma. [4]
The myeloid cell line normally produces granulocytes, erythrocytes, thrombocytes, macrophages and mast cells; the lymphoid cell line produces B, T, NK and plasma cells. Lymphomas, lymphocytic leukemias, and myeloma are from the lymphoid line, while acute and chronic myelogenous leukemia, myelodysplastic syndromes and myeloproliferative diseases ...
Mantle cell lymphoma (MCL) is a type of B-cell lymphoma and one of the rarest forms of non-Hodgkin's lymphomas comprising approximately 6% of diagnosed cases. [75] Burkitt lymphoma: C83.7: 1784: Burkitt lymphoma (also known as Burkitt's tumor or malignant lymphoma, Burkitt's type) is a type of B-cell lymphoma that is categorized into one of ...
A series of studies, principally from the Mayo Clinic, have indicated that patients with an abnormal free kappa to free lambda ratio have an increased risk of progression to active myeloma from precursor conditions including monoclonal gammopathy of undetermined significance (MGUS), [32] [33] smouldering myeloma [34] and solitary plasmacytoma ...
