title: [Low-grade gastric MALT lymphoma and helicobacter heilmannii (Gastrospirillum hominis].
abstract: We report the fourth case of low-grade gastric MALT lymphoma associated to Helicobacter heilmannii. This spiral organism may be present in the gastric mucosa of animals where it is non pathogenic while, in humans, its presence is always associated with chronic gastritis. In this case, Helicobacter heilmannii was observed in the absence of Helicobacter pylori. Regression of endoscopic and histological lesions after Helicobacter heilmannii eradication suggests its role in gastric lymphoma. This observation underlines the need for searching for Helicobacter heilmannii by careful histological examination, in the absence of Helicobacter pylori, and the importance of its eradication in the treatment of gastric lymphoma.
