Diffuse large B-cell lymphoma (DLBCL) is a cancer of B cells, a type of lymphocyte that is responsible for producing antibodies.It is the most common form of non-Hodgkin lymphoma among adults, [1] with an annual incidence of 7–8 cases per 100,000 people per year in the US and UK.
Non-Hodgkin’s lymphoma (NHL) is one of the most common forms of blood cancer.1 The American Cancer Society estimates that about 81,560 people in the U.S. will be diagnosed with NHL and about ...
Micrograph showing Hodgkin's lymphoma, a type of B cell lymphoma that is usually considered separate from other B cell lymphomas. Field stain. CT scan of primary B cell lymphoma in the left ilium, as diffuse cortical and trabecular thickening of the hemipelvis, mimicking Paget's disease.
It has a 5-year overall survival rate of 40–55%, although the PCDLBCL-O variant has a better prognosis than cases in which the legs are involved. [ 5 ] Most lymphomas begin in a lymph node , mucosa-associated lymphoid tissue , the spleen , or another lymphoid tissue within the lymphatic system and then may spread to the skin.
FA-DLBCL also differs from DLBCLCI in that it usually presents as infiltrates rather than tumors and is a far less aggressive and in many cases a relatively benign disease. [14] Here, it is considered in the differential diagnosis of DLBCL-CI and more fully described elsewhere (see fibrin-associated diffuse large B-cell lymphoma).
Aggressive lymphoma, also known as high-grade lymphoma, is a group of fast growing non-Hodgkin lymphoma. [1]There are several subtypes of aggressive lymphoma. These include AIDS-associated lymphoma, angioimmunoblastic lymphoma, Burkitt lymphoma, central nervous system (CNS) lymphoma, diffuse large B-cell lymphoma (DLBCL), mantle cell lymphoma (MCL) and peripheral T-cell lymphoma. [1]
Primary central nervous system lymphoma (PCNSL), also termed primary diffuse large B-cell lymphoma of the central nervous system (DLBCL-CNS), [2] is a primary intracranial tumor appearing mostly in patients with severe immunodeficiency (typically patients with AIDS). It is a subtype and one of the most aggressive of the diffuse large B-cell ...
Epstein–Barr virus positive diffuse large B-cell lymphoma, not otherwise specified (EBV+ DLBCL, NOS) is a form of diffuse large B-cell lymphomas (DLBCL) accounting for around 10-15% of DLBCL cases. DLBCL are lymphomas in which B-cell lymphocytes proliferate excessively, invade multiple tissues, and often causes life-threatening tissue damage.
