title: Synchronous primary adenocarcinoma, mucosa-associated lymphoid tissue lymphoma and a stromal tumor in a Helicobacter pylori-infected stomach.
abstract: We report the case of a 78-year-old man with Helicobacter pylori infection and three primary neoplasms of the stomach: adenocarcinoma, mucosa-associated lymphoid tissue (MALT) lymphoma and a gastrointestinal stromal cell tumor. Helicobacter pylori infection is associated with gastric carcinoma and MALT lymphoma, although their simultaneous occurrence is rare. Gastrointestinal stromal cell tumors have not been associated with infection to date. This appears to be the first report of the synchronous occurrence of these three gastric tumors.
