AIDS-related lymphoma describes lymphomas occurring in patients with acquired immunodeficiency syndrome (). [1] [2]A lymphoma is a type of cancer arising from lymphoid cells.In AIDS, the incidence of non-Hodgkin's lymphoma, primary cerebral lymphoma and Hodgkin's disease are all increased.
[1] [2] Because these tissues are all intimately connected through both the circulatory system and the immune system, a disease affecting one will often affect the others as well, making aplasia, myeloproliferation and lymphoproliferation (and thus the leukemias and the lymphomas) closely related and often overlapping problems.
Chronic lymphocytic leukemia (CLL) and small cell lymphocytic lymphoma (SLL) are different manifestations of the same disease and are managed in the same way. [21] When the abnormal lymphocytes are located mostly in the lymph nodes, it is referred to as SLL; when the abnormal lymphocytes are mostly in the blood and bone marrow, it is called CLL ...
T-cell lymphoma is a rare form of cancerous lymphoma affecting T-cells. [1] Lymphoma arises mainly from the uncontrolled proliferation of lymphocytes, such as T-cells, and can become cancerous. [2] T-cell lymphoma is categorized under Non-Hodgkin lymphoma (NHL) and represents less than 15% of all Non-Hodgkin's diseases in the category. [3]
Intravascular lymphomas (IVL) are rare cancers in which malignant lymphocytes proliferate and accumulate within blood vessels. Almost all other types of lymphoma involve the proliferation and accumulation of malignant lymphocytes in lymph nodes, other parts of the lymphatic system (e.g. the spleen), and various non-lymphatic organs (e.g. bone marrow and liver) but not in blood vessels.
Small cleaved cells are a distinctive type of cell that appears in certain types of lymphoma. When used to uniquely identify a type of lymphoma, they are usually categorized as follicular or diffuse . The "small cleaved cells" are usually centrocytes that express B-cell markers such as CD20.
Its prognosis appears to be slightly worse than that seen in extranodal and splenic marginal zone lymphomas [72] with ~15% of people progressing to a more aggressive lymphoma, diffuse large B cell lymphoma, at median time of ~4.5 years after the diagnosis of NMZL. [74] In different studies, people with the disease have 5 year survival rates of ...
T-lymphoblastic leukemia/lymphoma (WHO 2008), [1]: 219 previously labeled precursor T-lymphoblastic leukemia/lymphoma (WHO 2001) [1]: 219 is a form of lymphoid leukemia [2] [3] and lymphoma [4] in which too many T-cell lymphoblasts (immature white blood cells) are found in the blood, bone marrow, and tissues, particularly mediastinal lymph nodes.
