A 67-year-old man was diagnosed with primary gastric malignant lymphoma by an endoscopic examination. Endoscopy revealed irregular ulcerative regions from body to antrum of the stomach. With a diagnosis of diffuse large B-cell lymphoma based on the biopsy finding, the patient was treated with R-CHOP chemotherapy. After three cycles of chemotherapy, a tight stenosis was located at the antrum of the stomach. Total gastrectomy was performed due to an obstruction. Pathological diagnosis was complete response. It was thought that the tumor organization rapidly disappeared due to the effectiveness of the chemotherapy, and that the origin of the stricture caused fibrosis.
