초록
Mucosa-associated lymphoid tissue (MALT) lymphomas are typically found in the stomach, while colonic MALT lymphoma israrely found. Considering its rarity, definitive treatment of colonic MALT lymphoma has not been established. Different from thatin the stomach, Helicobacter pylori infection might play a minor role while determining the treatment of colonic MALT lymphoma. If colonic MALT lymphoma is localized, treatment options are surgical resection, radiation, endoscopic resection, or combinationtherapy. Here, we report a case of residual colonic MALT lymphoma after endoscopic mucosal resection, which was a 1.5-cm-sizedtumor confined to the superficial wall of the rectum. The lesion was successfully treated using the endoscopic submucosal dissectiontechnique. The patient remained disease-free for 4 years. This case provides rationale for endoscopic submucosal dissectiontreatment as a salvage therapy for residual tumors in properly selected patients with colonic MALT lymphoma.
