[Association of a low-grade MALT lymphoma and a slightly differentiated adenocarcinoma of the stomach].
The development of synchronous gastric adenocarcinoma and primary gastric lymphoma is rare. We report a case of low grade B-cell lymphoma of mucosa associated lymphoid tissue intermingled with a gastric adenocarcinoma and without Helicobacter pylori infection. This observation leads to discuss the pathogenesis of these tumors and the role of Helicobacter pylori infection in the development of gastric lymphoma and carcinoma.
