Non-MALT marginal zone lymphomas.
The concept of marginal zone B-cell lymphomas was developed in the 1990s for lymphomas whose cells originate from B lymphocytes normally present in a distinct anatomical location, the so-called ‘marginal zone’ (MZ). MZ has been described in the lymphoid organs—spleen and lymph nodes—and in nonlymphoid organs—mucosa-associated lymphoid tissue (MALT) or non-mucosal tissue such as skin, orbit and ...
متن کاملMarginal zone lymphomas: management of nodal, splenic, and MALT NHL.
Marginal zone lymphomas are indolent B-cell lymphomas that originate from the marginal zone of B-cell follicles. For several subtypes, the initiation of disease appears to be a consequence of chronic infection and/ or inflammation. While the initial lymphoid hyperplasia is driven by physiologic antigenic stimulation, additional oncogenic events, such as chromosomal translocations leading to con...
متن کاملNon-MALT marginal zone B-cell lymphomas: a description of clinical presentation and outcome in 124 patients.
Marginal zone B-cell lymphoma (MZL) is a recently individualized lymphoma that encompasses mucosa-associated lymphoid tissue (MALT) lymphoma, splenic lymphoma with or without villous lymphocytes, and nodal lymphoma with or without monocytoid B-cells. If the clinical description and outcome of MALT lymphoma is well known, this is not the case for the other subtypes. We reviewed 124 patients pres...
متن کاملCARMA1 and chromosomal translocations in extranodal marginal zone B-cell lymphomas of MALT type or diffuse large B-cell lymphomas.
We analyzed the configuration of the CARMA1 gene, encoding a protein that closely interacts with BCL10 and MALT1, in a series of 120 extranodal marginal zone B-cell lymphomas of MALT-type and 35 diffuse large B-cell lymphomas. Our study suggests that CARMA1 is not targeted by chromosomal translocations in these lymphoma entities.
متن کاملPurine analogs in marginal-zone lymphomas.
In an area of lymphoma classification still being defined, marginal-zone lymphomas have distinctive immunohistochemical and cytogenetic features that distinguish them from mantle-cell and follicular lymphomas. There are three subtypes: the extranodal mucosa-associated lymphoid tissue (MALT) lymphomas, the nodal monocytoid B-cell (MBCL) lymphomas, and the splenic marginal-zone lymphomas. The MAL...
