摘要

Mucosa-associated lymphoid tissue (MALT) lymphoma of the stomach is the most common extranodal lymphoma of the gastrointestinal tract. It is usually accompanied by Helicobacter pylori infection, and eradication of H. pylori remains the mainstay of treatment for gastric MALT lymphoma. However, there is no consensus on the second-line treatment for patients with gastric MALT lymphoma who do not improve after successful H. pylori eradication. Here, we report the case of a 34-year-old woman who presented with a polypoid type of gastric MALT lymphoma on the greater curvature side of the upper body. Despite successful H. pylori eradication, the tumor did not regress after 6 months. Because the tumor had a semipedunculated polypoid morphology, gastric polypectomy was implemented as a second-line treatment. No recurrence occurred during the 3-year follow-up period. We suggest that gastric polypectomy be considered an alternative treatment modality for polypoid gastric MALT lymphoma that is unresponsive to H. pylori eradication.
