Mantle cell lymphoma (MCL) is a type of non-Hodgkin's lymphoma, comprising about 6% of cases. [ 1 ] [ 2 ] It is named for the mantle zone of the lymph nodes where it develops. [ 3 ] [ 4 ] The term 'mantle cell lymphoma' was first adopted by Raffeld and Jaffe in 1991.

CD20. Approximately 95% of B-cell lymphomas express CD20, but CD20 is not critical for B-cell survival. Clonal B-cells spontaneously mutate the idiotypic region of their immunoglobulin. This high mutation rate makes them prone to the selection of B-cells lacking the CD20 antigen following treatment with CD20-targeting monoclonal antibodies.
Mantle cell lymphoma: The monoclonal B-cells in this aggressive lymphoma are CD5+ in most cases, CD10−, CD23−, CD43+, CD103−, complete Ig+, and express cyclin D1; these cells have translocations between chromosomes 11 and 14 in >95% of cases and in many cases overexpress the SOX11 transcription factor gene.

Burkitt lymphoma is commonly associated with the infection of B cell lymphocytes with the EBV and in these cases is considered to be one form of the Epstein–Barr virus-associated lymphoproliferative diseases. [8] The endemic variant of Burkitt lymphoma is in almost all cases associated with EBV infection. [9]
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 ...
The use of rituximab has been established for the treatment of B-cell–derived hematologic malignancies, including follicular lymphoma (FL) and diffuse large B-cell lymphoma (DLBCL). [ 7 ] In addition to cure-directed treatment, people can benefit from self-care to manage symptoms.
In situ lymphoid neoplasia (ISLN, also termed in situ lymphoma) is a precancerous condition newly classified by the World Health Organization in 2016. The Organization recognized two subtypes of ISLN: in situ follicular neoplasia (ISFN) and in situ mantle cell neoplasia (ISMCL). [1]
