Waldenstrom Macroglobulinemia (C0024419)
|
|---|
| Definition (MSH) | A lymphoproliferative disorder characterized by pleomorphic B-LYMPHOCYTES including PLASMA CELLS, with increased levels of monoclonal serum IMMUNOGLOBULIN M. There is lymphoplasmacytic cells infiltration into bone marrow and often other tissues, also known as lymphoplasmacytic lymphoma. Clinical features include ANEMIA; HEMORRHAGES; and hyperviscosity. |
| Definition (CSP) | plasma cell dyscrasia resembling leukemia, with cells of lymphocytic, plasmacytic, or intermediate morphology, that secrete an IgM monoclonal component. |
| Definition (NCI) | A rare cancer of the lymph cells that causes the body to produce abnormal levels of plasma cells (plasmacytosis) and lymphocytes (lymphocytosis) in the bone marrow. Waldenstrom's macroglobulinemia may also cause a decrease in the number of red blood cells (anemia) and enlargement of the liver (hepatomegaly), spleen (splenomegaly), or glands (adenopathy). |
| Definition (NCI) | (MAK-ro-GLOB-u-li-NE-me-uh) A condition in which the blood contains high levels of large proteins and is too thick to flow through small blood vessels. One type is Waldenstrom's macroglobulinemia, which is a type of cancer. |
| Definition (NCI) | A clonal neoplasm of small B-lymphocytes, lymphoplasmacytoid cells, and plasma cells involving the bone marrow, lymph nodes, and the spleen. The majority of patients have a serum IgM paraprotein. Lymphoplasmacytic lymphoma/ Waldenstrom's Macroglobulinemia is a relatively rare condition accounting for approximately 2% of hematologic malignancies. Symptoms include: weakness and fatigue, hemorrhagic manifestations, weight loss and visual disturbances. Physical findings include: hepatomegaly, splenomegaly, fundic changes, adenopathy, neurologic abnormalities and purpura. The most common laboratory finding is anemia. Treatment includes: chemotherapy (alkylating agents, nucleoside analogues) radiotherapy and plasmapheresis. Bone marrow transplant is being investigated. Asymptomatic patients may be monitored without treatment until complications occur. |
