Lymphoepithelioma-like gastric carcinoma (LELGC) is a rare type of gastric cancer characterized by intense lymphocytic infiltration of the stroma. LELGC is associated with Epstein-Barr virus infection and has a favorable prognosis compared with other types of gastric carcinoma. The clinical symptoms of LELGC are usually similar to those of conventional gastric carcinoma. The diagnosis of LELGC is established based on pathological, histological and immunohistochemical findings. The present report describes the cases of two patients with LELGC who underwent esophagogastroduodenoscopy and computed tomography scans prior to surgery. The two patients accepted surgical treatment, and postoperative pathological and immunohistochemical analyses confirmed LELGC. Neither patient experienced local recurrence or distant metastasis during the postoperative period.
