<prompt> Answer this question truthfullyCan you provide a summary of B-cell lymphoma?  <response>: <reason> B-cell lymphomas include both Hodgkins lymphomas and most Non-Hodgkins lymphomas. They are typically divided into low and high grade, typically corresponding to indolent slow-growing lymphomas and aggressive lymphomas, respectively.. The most commonly used classification system is the WHO classification, a convergence of more than one, older classification systems.Five account for nearly three out of four patients with non-Hodgkin lymphoma: Diffuse large B cell lymphoma Follicular lymphoma Mucosa-Associated Lymphatic Tissue lymphoma MALT Small cell lymphocytic lymphoma overlaps with Chronic lymphocytic leukemia Mantle cell lymphoma MCLThe remaining forms are much less common: Burkitt lymphoma Mediastinal large B cell lymphoma Waldenström macroglobulinemia Nodal marginal zone B cell lymphoma NMZL Splenic marginal zone lymphoma SMZL Extranodal marginal zone B cell lymphoma Intravascular large B cell lymphoma Primary effusion lymphoma Lymphomatoid granulomatosis T cellhistiocyte-rich large B-cell lymphoma Primary central nervous system lymphoma Primary cutaneous diffuse large B-cell lymphoma, leg type Primary cutaneous DLBCL, leg type EBV positive diffuse large B-cell lymphoma of the elderly Diffuse large B-cell lymphoma associated with inflammation Intravascular large B-cell lymphoma ALK-positive large B-cell lymphoma Plasmablastic lymphoma Large B-cell lymphoma arising in HHV8-associated multicentric Castlemans disease B-cell lymphoma, unclassifiable with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma B-cell lymphoma, unclassifiable with features intermediate between diffuse large B-cell lymphoma and classical Hodgkin lymphomaAdditionally, some researchers separate out lymphomas that appear result from other immune system disorders, such as AIDS-related lymphoma. Classic Hodgkins lymphoma and nodular lymphocyte predominant Hodgkins lymphoma are now considered forms of B-cell lymphoma.
