Mucosa-associated lymphoid tissue (MALT) lymphoma predominantly involves the gastrointestinal tract, with the stomach being the most commonly affected site. Colonic involvement is quite rare. Hence, the etiology, clinical characteristics, treatment, and outcome of colonic MALT lymphoma are not well established. This paper reports a case of MALT lymphoma of the transverse colon, presenting as a subepithelial tumor in a 50-year-old woman. The patient received 3,060 cGy in 17 fractions with external beam radiation therapy for three weeks. At 2 months after radiation therapy, a colonoscopy examination revealed complete resolution and a scar change of the lesion. The follow-up at 24 months revealed no evidence of tumor recurrence after radiation therapy.
黏膜相关淋巴组织（MALT）淋巴瘤主要累及胃肠道，以胃最常受累。结直肠受累相当罕见。因此，结直肠黏膜相关淋巴组织淋巴瘤的病因、临床特征、治疗和预后尚不清楚。本文报告 1 例 50 岁女性横结肠 MALT 淋巴瘤，表现为黏膜下肿瘤。患者接受了 3060cGy 的 17 次分割外照射治疗，共 3 周。放疗后 2 个月，结肠镜检查显示病变完全缓解和瘢痕改变。24 个月随访时，放疗后无肿瘤复发证据。
