Lymphoepithelioma-like carcinoma is distinct entity of Epstein-Barr virus (EBV)-associated gastric carcinomas, characterized by the presence of a lymphoid stroma and small nests of cancer cells that are uniformly distributed throughout the lymphoid stroma. Epithelioid granulomas with multinucleated giant cells are extremely rare in the tumor tissue. The presence of epithelioid granuloma with prominent lymphocyte infiltration is associated with a favorable prognosis. This lesion tends to form a bulging mass in the submucosa. We report herein a lymphoepithelioma-like carcinoma of the stomach with epitheliod granulomas presenting as a bulging mass on CT scan and correlate them with the pathology. Clinicians and radiologist should recognize the presence of such a tumor.
