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 ...
Plasma cell leukemia (PCL) is a plasma cell dyscrasia, i.e. a disease involving the malignant degeneration of a subtype of white blood cells called plasma cells.It is the terminal stage and most aggressive form of these dyscrasias, constituting 2% to 4% of all cases of plasma cell malignancies.
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.
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.
In medicine, both ancient and modern, a dyscrasia is any of various disorders. The word has ancient Greek roots meaning "bad mixture". [1] The concept of dyscrasia was developed by the Greek physician Galen (129–216 AD), who elaborated a model of health and disease as a structure of elements, qualities, humors, organs, and temperaments (based on earlier humorism).
Monoclonal immunoglobulins are produced by monoclonal plasma cells, which are found in a variety of plasma cell dyscrasias. The deposition of monoclonal immunoglobulins on the basement membrane of the kidney causes renal impairment. As well as the kidney, MIDD may also affect the liver, heart, peripheral nerves, lung and skin.
Mucus often changes colors when dead cells, germs and other substances, like blood or tobacco smoke, gets mixed with it, according to Cleveland Clinic. These colors include:
[2] [3] [4] Acquired dysfibrinogenemia is a non-hereditary disorder in which fibrinogen is dysfunctional due to the presence of liver disease, autoimmune disease, a plasma cell dyscrasias, or certain cancers. It is associated primarily with pathological bleeding. [5]
