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.

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.
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.

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.
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.
Diffuse large B-cell lymphoma is a highly aggressive type of B-cell lymphoma. It is distinguished by the widespread proliferation of large neoplastic B lymphocytes with nuclei that are equal to or larger than normal histiocytic nuclei. [10] The illness manifests with B symptoms at an advanced stage of the illness.
