Small bowel mucosa‐associated lymphoid tissue lymphoma: A case report and literature review

Small intestine marginal B cell lymphoma of the mucosa‐associated type (MALT lymphoma) is relatively rare compared to gastric mucosa‐associated lymphoma tissue (MALT) lymphoma, and comprised only about less than 10% of primary small intestinal tumor cases. However, with advances in video capsule enteroscopy and balloon‐assisted enteroscopy, more cases of small bowel MALT lymphoma are expected to be discovered via endoscopy. The pathogenesis, endoscopic features, and treatment strategy, including Helicobacter pylori eradication therapy, remain an issue and require further clinical trial or studies to be resolved. Here, we report the case of a 67‐year‐old man with jejunal MALT lymphoma presenting with nearly total obstruction of his bowel lumen. He underwent segmental small bowel resection for the stricture without recurrence.
