Abstract

Mucosa-associated lymphoid tissue (MALT) lymphoma is a neoplasm with low-grade malignancy that arises from the MALT of various organs. Among the various MALT lymphomas, gastric MALT lymphoma is the most frequently reported, and it has been correlated with Helicobacter pylori infection. In contrast, duodenal MALT lymphoma is very rare, and a relationship with H. pylori has not been established. This case report describes a very rare case of MALT lymphoma arising in both the stomach and duodenum that regressed after eradication of H. pylori.
