Marginal zone lymphoma translocation. Jan 8, 2026 · Transformation to aggressive diffuse large B-cell lymphoma occurs in 3% to 15% of cases and is associated with the accumulation of genetic lesions, particularly in cell cycle, NF-κB, and epigenetic regulators, with subtype-specific drivers including TNFAIP3, TP53, and CDKN2A/B alterations. 2 For relapsed or refractory MZL, standard options include anti-CD20-based regimens, lenalidomide–rituximab, and They are lymphocytes of the B-cell line that originate and mature in secondary lymphoid follicles and then move to the marginal zones of mucosa-associated lymphoid tissue (MALT), the spleen, or lymph nodes. The role of genetic alterations, particularly translocations, is pivotal in understanding the etiology and progression of this disease. Feb 9, 2022 · Gailllard B, Cornillet-Lefebvre P, Le QH, et al. Apr 26, 2023 · Marginal zone lymphomas and lymphoplasmacytic lymphomas may undergo a variety of histologic transformations. Usually DLBCL arises from normal B cells, but it can also represent a malignant transformation of other types of lymphoma (particularly marginal zone lymphomas [7]) or, in rare cases termed Richter's transformation, chronic lymphocytic leukemia. We would like to show you a description here but the site won’t allow us. [8] We report a rare phenotype of Stage IV extranodal marginal zone lymphoma (MALT lymphoma) manifesting as diffuse, asymptomatic skeletal muscle and bone marrow infiltration in a 60-year-old female. The most common form of transformation is to diffuse large B-cell lymphoma, not otherwise specified, typically with a non–germinal center phenotype. 6 days ago · Other B cell NHL subtypes, such as extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (EMZL-MALT) and follicular lymphoma, can also affect the oropharynx, however, are less common. mbzknsbnusysrshoihyswucruwawnxgcmzqkccchubtrrlmbcxgmuyhb
