Helicobacter pylori infection and gastric MALT lymphoma.
Helicobacter pylori infection is implicated in the development of two different gastric cancers: gastric adenocarcinoma and gastric MALT lymphoma. The association with the gastric MALT lymphoma is strong and causal. It is currently the only cancer which can be treated by a simple antibiotic treatment. However, the evolution of an H. pylori infection towards lymphoma is exceptional. Host suscept...
متن کاملHelicobacter pylori infection and gastric lymphoma.
Gastric lymphoma of mucosa associated lymphoid tissue (MALT) has characteristic clinicopathological features that are different from nodal-type B cell lymphomas. Before a lymphoma can arise within the stomach, MALT has to be acquired as part of a response to an immunological stimulus. In most instances, gastric MALT is acquired in response to infection by Helicobacter pylori. There are several ...
متن کاملPrimary gastric lymphoma and Helicobacter pylori infection with gastric amyloidosis.
Primary gastric lymphoma, an uncommon gastric tumor caused by infection with Helicobacter pylori, is rarely associated with gastric amyloidosis. Chronic bacterial infection is known to cause amyloidosis. We report a 53-year-old man who had an antral and duodenal mass with narrowing and ulceration on endoscopy and CT scan; endoscopic biopsy revealed gastric amyloidosis. Rapid urease test and ser...
متن کاملLymphocytic gastritis and Helicobacter pylori infection in gastric lymphoma.
Lymphocytic gastritis and primary gastric lymphoma are rare conditions with unknown aetiology. It has recently been suggested that Helicobacter pylori has a role in the pathogenesis of both of them. The occurrence of lymphocytic gastritis and H pylori was studied in a series of patients with primary gastric lymphoma. The cases of primary gastric lymphomas (n = 35) diagnosed in years 1970-1993 w...
متن کاملGastric MALT lymphoma and Helicobacter pylori.
The majority of low grade gastric lymphomas arise within acquired organized lymphoid tissue, which has all the features of MALT. This MALT is specifically acquired most commonly in response to infection of the gastric mucosa by H pylori. The lymphocytes within this MALT are therefore programmed to respond to this organism and the neoplastic cells of the lymphoma that may develop within this acq...
