Purine 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...
متن کاملCASE REPORT Regression of gastric high grade mucosa associated lymphoid tissue (MALT) lymphoma after Helicobacter pylori eradication
Background—Most low grade gastric lymphomas arising from the mucosa associated lymphoid tissue (MALT) are related to Helicobacter pylori colonisation. Cases with disease limited to the stomach can be cured after H pylori eradication and remain in remission for years. In contrast, high grade lymphomas of the stomach, although also related to H pylori, do not usually respond to eradica-
متن کاملClinicopathological study of primary gastric lymphoma.
OBJECTIVE To present a histopathologic and immunohistochemical analysis of primary gastric lymphomas that was reclassified according to the new World Health Organization classification of lymphoid neoplasms. METHODS We reviewed the morphological and immunohistochemical features of 28 patients with gastric lymphomas, diagnosed in the Department of Pathology at the University Hospital of Tishre...
متن کاملHelicobacter pylori and Gastric Mucosa-associated Lymphoid Tissue (MALT) Lymphoma: Updated Review of Clinical Outcomes and the Molecular Pathogenesis
In most H. pylori-positive patients, gastric low-grade mucosa-associated lymphoid tissue (MALT) lymphomas regress both endoscopically and histopathologically after H. pylori eradication, but no factors that can be predictive of the response to the eradication have been definitively identified, and there is little information on how to determine the optimal observation period before additional t...
متن کاملKaryometric Comparison of Splenic and Gastric Marginal Zone Lymphomas
BACKGROUND Marginal zone lymphomas are indolent B-cell lymphomas associated with autoimmunity and chronic inflammation. The two most frequent variants are mucosa associated lymphoid tissues marginal zone lymphomas and splenic marginal zone lymphomas. The aim of the study was to determine if it is possible to classify splenic and gastric lymphomas according to karyometric features. METHODS The...
