Lymphoepithelioma-like carcinoma is a distinct entity among Epstein-Barr virus (EBV)-associated gastric carcinomas, characterized by the presence of a lymphoid stroma with small nests of cancer cells uniformly distributed throughout. Epithelioid granulomas with multinucleated giant cells are extremely rare in the tumor tissue. The presence of epithelioid granulomas with prominent lymphocyte infiltration is associated with a favorable prognosis. This lesion tends to form a bulging mass in the submucosa. In the present study, we report a lymphoepithelioma-like carcinoma of the stomach with epithelioid granulomas which appeared as a bulging mass in CT scanning and correlate it with the pathology. Clinicians and radiologists should recognize the features of such tumors.
淋巴上皮瘤样癌是爱泼斯坦-巴尔病毒(EBV)相关胃癌中的一种独特类型,其特征是存在淋巴样间质,癌细胞小巢均匀分布于其中。肿瘤组织中出现含多核巨细胞的上皮样肉芽肿极为罕见。存在伴有显著淋巴细胞浸润的上皮样肉芽肿与预后良好相关。该病变倾向于在黏膜下层形成隆起性肿块。在本研究中,我们报告了一例胃淋巴上皮瘤样癌伴有上皮样肉芽肿,其在CT扫描中表现为隆起性肿块,并将其与病理结果相关联。临床医生和放射科医生应认识到这类肿瘤的特征。
