Abstract

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.
