Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) is an aggressive malignant digestive system lymphoma. We report the case of a 68-year-old Asian woman who was diagnosed with MEITL of the duodenum and small intestine due to intestinal obstruction. MEITL is mainly located in the small intestine, and duodenal lesions are rare. Therefore, the endoscopic appearance of MEITL in the duodenum has been reported in only a few cases. In this case, we observed the initial and advanced endoscopic findings of MEITL in the duodenum. The initial findings were only slight mucosal changes; therefore, careful observation is required to detect early-stage MEITL.
单形性上皮趋化性肠道T细胞淋巴瘤（MEITL）是一种侵袭性恶性消化系统淋巴瘤。我们报告一例68岁亚洲女性因肠梗阻被诊断为十二指肠和小肠MEITL的病例。MEITL主要位于小肠，十二指肠病变罕见。因此，仅有少数病例报道了十二指肠MEITL的内镜表现。在本病例中，我们观察到十二指肠MEITL的初期和进展期内镜表现。初期表现仅为轻微黏膜改变；因此，检测早期MEITL需要仔细观察。
