Lymphoepithelioma-like gastric carcinoma (LELGC) is a rare neoplasm of the stomach that accounts for 1-4% of all gastric cancer cases. It is characterized by the presence of a lymphoid stroma with cells arranged primarily in micro alveolar, thin trabecular and primitive tubular patterns or isolated cells. In the present study, the case of a 50-year-old male patient with LELGC and rectal laterally spreading tumor is presented. Following endoscopic submucosal dissection, a diagnosis of carcinoma was reached and the patient underwent total radical gastrectomy. The postoperative pathological stage was IA T1bN0cM0 according to the Tumor-Node-Metastasis classification of gastric carcinoma, and the patient recovered well. The present case is reported to summarize the endoscopic and pathological characteristics of LELGC.
淋巴上皮瘤样胃癌（LELGC）是一种罕见的胃部肿瘤，占所有胃癌病例的1%-4%。其特征是存在淋巴样间质，细胞主要呈微腺泡状、细小梁状和原始管状排列或单个细胞。在本研究中，报告了一例50岁男性LELGC患者合并直肠侧向发育型肿瘤的病例。在内镜下黏膜下剥离术后，确诊为癌，患者接受了根治性全胃切除术。根据胃癌的肿瘤-淋巴结-转移分类，术后病理分期为IA期T1bN0cM0，患者恢复良好。报告本病例以总结LELGC的内镜和病理特征。
