We report the cases of 5 patients with gastric cancer with lymphoid stroma, aged from 40 to 66 years. The tumor was located in the upper and the middle third of stomach in four patients. Using in situ hybridization, the tumor was Epstein-Barr virus-positive in all patients whereas immunohistochemical analysis was negative. Four patients had total gastrectomy associated in two cases with splenectomy and caudal pancreatic resection. The last patient had subtotal gastrectomy. One patient was lost to follow-up. After a mean follow-up of 31 months, 4 patients are alive and free of local recurrence.
