Abstract

The connection between Helicobacter pylori and mucosa-associated lymphoid tissue (MALT) lymphoma is well established. H. pylori eradication is the initial treatment for MALT lymphoma. However, in H. pylori negative cases or unresponsive patients after successful eradication, radiation, systemic therapies, and surgical resection should be considered. Also local treatment modalities such as endoscopic mucosal resection (EMR) may be a therapeutic option in cases of low grade, localized MALT lymphoma. Herein, we report a case of a 53-year-old man who had a persistent endoscopic mass and tumor cells on histology for 5 months despite H. pylori eradication. Because of no early response to H. pylori eradication, the possibility of the presence of a high-grade lymphoma component, the proximal location of the tumor, and the exophytic nature of the tumor, we decided to perform EMR for complete resection. After EMR, the patient remained in complete remission throughout the 15-month follow up. In our case, endoscopic resection could lead to a more rapid complete remission. Therefore, we suggest that endoscopic resection may be a useful option for low-grade exophytic-type gastric MALT lymphoma treatment with no response to H. pylori eradication.
