Extranodal marginal zone lymphoma (EMZL) of mucosa-associated lymphoid tissue (MALT) commonly affects the gastrointestinal (GI) tract but rarely occurs within the colon. Colonic EMZL is a rare diagnosis accounting for 2.5% of EMZL and less than 0.5% of colon cancers. We present a unique case of asymptomatic colonic EMZL diagnosed on a routine surveillance colonoscopy. The lymphoma was confined to a single colonic polyp presenting endoscopically as a sessile polypoid lesion at the recto-sigmoid junction. The patient was successfully treated with polypectomy with no recurrence of the disease.
黏膜相关淋巴组织（MALT）的结外边缘区淋巴瘤（EMZL）通常累及胃肠道，但很少发生在结肠内。结肠EMZL是一种罕见的诊断，占EMZL的2.5%，占结肠癌的不到0.5%。我们报告一例在常规监测结肠镜检查时诊断出的无症状结肠EMZL的独特病例。淋巴瘤局限于一个单一的结肠息肉，在内镜下表现为直肠乙状结肠交界处的无蒂息肉样病变。患者通过息肉切除术成功治愈，疾病未复发。
