Primary gastric malignant lymphoma is a rare tumor. The complications associated with lymphoma are perforation, bleeding, or upper gastrointestinal stricture. While it is well known that perforations in gastric lymphoma often occurs during chemotherapy, spontaneous perforation is extremely rare in patients who did not receive chemotherapy. This complication requires a surgical treatment.
