BACKGROUND
The gastrointestinal tract is a well-known extranodal site of lymphoma. B-cell lymphoma is the most common type, while T-cell lymphoma is uncommon. Primary gastrointestinal lymphoma mainly occurs in the stomach and small intestine, and the colon is less frequently involved, especially in females.
CASE SUMMARY
A 45-year-old woman was admitted to our hospital for physical examination. Gastroenteroscopy revealed a visible pedunculated polyp in the transverse colon, for which endoscopic submucosal dissection (ESD) was performed. Pathology suggested highly active proliferation of T lymphocytes with atypical hyperplasia.
CONCLUSION
A middle-aged female patient was found to have colonic T-cell lymphoma by endoscopy. The lesion was successfully removed by ESD, and the surgical margin was negative. It is essential to raise awareness of colonic T-cell lymphoma and choose the appropriate treatment.
背景
胃肠道是淋巴瘤常见的结外受累部位。B细胞淋巴瘤是最常见的类型，而T细胞淋巴瘤并不常见。原发性胃肠道淋巴瘤主要发生在胃和小肠，结肠受累较少，尤其是女性。
病例摘要
一名45岁女性因体检入院。胃镜检查发现横结肠有一个带蒂息肉，遂行内镜下黏膜剥离术（ESD）。病理提示T淋巴细胞高度活跃增殖伴非典型增生。
结论
一名中年女性患者经内镜检查发现结肠T细胞淋巴瘤。病变通过ESD成功切除，手术切缘阴性。提高对结肠T细胞淋巴瘤的认识并选择合适的治疗方法至关重要。
