CASE REPORT Regression of gastric high grade mucosa associated lymphoid tissue (MALT) lymphoma after Helicobacter pylori eradication

چکیده
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-

Predictive value of endoscopic ultrasonography for regression of gastric low grade and high grade MALT lymphomas after eradication of Helicobacter pylori.
BACKGROUND While a close association between gastric mucosa associated lymphoid tissue (MALT) lymphoma and Helicobacter pylori infection has been established, there are still cases which do not respond to H pylori eradication. AIMS To investigate the clinicopathological factors which may help predict the therapeutic efficacy of H pylori eradication in gastric MALT lymphoma. PATIENTS Forty o...

متن کاملHigh-grade Hepatic Mucosa-associated Lymphoid Tissue (MALT) Lymphoma Probably Transformed from the Low-grade Gastric MALT Lymphoma
The Mucosa-associated lymphoid tissue (MALT) lymphoma, which was first described in 1983, is known to be caused by chronic Helicobacter pylori (HP) infection, which triggers lymphoid infiltration and formation of organized lymphoid tissue. In approximately two thirds of cases of MALT, the lymphoma has been observed to regress after treatment of H. pylori infection; this provides strong evidence...
متن کاملRegression of colonic low grade B cell lymphoma of the mucosa associated lymphoid tissue type after eradication of Helicobacter pylori.
BACKGROUND Lymphoma of the mucosa associated lymphoid tissue (MALT) arising in the stomach has been shown to be related to Helicobacter pylori infection, and total regression of gastric lymphoma after successful eradication of H pylori has consistently been reported. MALT-type lymphoma at other localisations, however, has to our knowledge not been linked to H pylori, and eradication of the bact...
متن کاملCASE REPORT Regression of idiopathic thrombocytopenic purpura after endoscopic mucosal resection of gastric mucosa associated lymphoid tissue lymphoma
Recent reports have suggested an association between Helicobacter pylori infection and both gastric mucosa associated lymphoid tissue (MALT) lymphoma and thrombocytopenic purpura. Although treatments eradicating H pylori lead to regression of these diseases in some cases, the exact mechanisms are still controversial. This case report describes a patient with thrombocytopenic purpura accompanied...
