The B-cell lymphomas are types of lymphoma affecting B cells. Lymphomas are "blood cancers" in the lymph nodes . They develop more frequently in older adults and in immunocompromised individuals.
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.
Diffuse large B-cell lymphoma (DLBCL) is a type of high-grade NHL which is the most common type of NHL worldwide at affecting 30–40 percent of all NHL cases. [4] It is more prevalent in elderly patients with a median age of 70 years. Patients most often present with a rapidly growing tumor mass in single or multiple, nodal or extranodal sites.

Plasmablastic lymphoma lesions are most commonly rapidly growing, soft tissue masses [5] that may be ulcerating, bleeding, and/or painful. [6] In a recent (2020) review of published cases, individuals presenting with PBD were typically middle-aged or elderly (range 1–88 years; median age 58 tears) males (~73% of cases). [7]
The most common chemotherapy used for B-cell non-Hodgkin lymphoma is R-CHOP, which is a regimen of four drugs (cyclophosphamide, doxorubicin, vincristine, and prednisone) plus rituximab. [ 33 ] R-CHP with polatuzumab vedotin , an antibody-drug conjugate, was included as a category 1 preferred regimen for first-line DLBCL by the National ...
The tumor cells in Burkitt lymphoma generally strongly express markers of B cell differentiation (CD20, CD22, CD19), as well as CD10 and BCL6. The tumor cells are generally negative for BCL2 and TdT. The high mitotic activity of Burkitt lymphoma is confirmed by nearly 100% of the cells staining positive for Ki67.
T-cell/histiocyte-rich large B-cell lymphoma most commonly afflicts middle-aged (i.e. 49–57 years old) individuals but has been diagnosed in persons aged 4 [6] to 92 years. [2] The disease has a male predominance ranging between 1.7:1 [ 3 ] to 3:1 [ 2 ] in different studies.
