Mucosa-associated lymphoid tissue (MALT) lymphoma is a type of non-Hodgkin lymphoma with characteristic histopathological features and can occur in various extranodal sites, including the gastrointestinal tract. While gastric MALT lymphoma has been extensively researched, primary lymphoma presentation in the colorectal mucosa is rare and lacks any association with infection. Furthermore, there are currently no standardized treatment guidelines for this condition. This report presents a rare case of primary MALT lymphoma that manifested as a broad-based polyp. The diagnosis was confirmed through histopathological and immunohistochemical examination, and the polyp was resected endoscopically with the endoscopic submucosal dissection technique.
黏膜相关淋巴组织（MALT）淋巴瘤是一种具有特征性组织病理学特征的非霍奇金淋巴瘤，可发生于包括胃肠道在内的各种结外部位。虽然胃MALT淋巴瘤已得到广泛研究，但原发性淋巴瘤在结直肠黏膜中的表现罕见，且与感染无任何关联。此外，目前尚无针对这种疾病的标准化治疗指南。本报告介绍了一例罕见的原发性MALT淋巴瘤，表现为广基息肉。通过组织病理学和免疫组织化学检查确诊，采用内镜黏膜下剥离术在内镜下切除息肉。
