A 65-year-old male was diagnosed with Helicobacter pylori-negative gastric mucosal-associated lymphoid tissue (MALT)-lymphoma, measuring 46mm with a protruding shape and subepithelial appearance in the corpus-fundus junction. EUS showed mucosal involvement without parietal extension. After treatment with antibiotics and Rituximab, no endoscopic/histological response was observed at 12-month follow-up. After treatment option discussions in a multidisciplinary meeting, an en-bloc endoscopic submucosal dissection (ESD) was performed without complications. Histopathology revealed free deep and lateral margins. Follow-up at 6 and 12 months showed no endoscopic/histological recurrence. This report provides further support of ESD as a minimally invasive second-line treatment of MALT-lymphoma in selected patients.
