Abstract

|
Mucosa-associated lymphoid tissue (MALT) lymphomas are typically found in the stomach, while colonic MALT lymphoma is rarely found. Considering its rarity, definitive treatment of colonic MALT lymphoma has not been established. Different from that in 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 combination therapy. Here, we report a case of residual colonic MALT lymphoma after endoscopic mucosal resection, which was a 1.5-cm-sized tumor confined to the superficial wall of the rectum. The lesion was successfully treated using the endoscopic submucosal dissection technique. The patient remained disease-free for 4 years. This case provides rationale for endoscopic submucosal dissection treatment as a salvage therapy for residual tumors in properly selected patients with colonic MALT lymphoma.
