We report a case of malignant lymphoma of the duodenum with right atrial invasion. A 71-year-old man presented with anemia and exertional dyspnea. Gastric fibroscopy showed a duodenal tumor pathologically diagnosed as diffuse large B-cell lymphoma(DLBCL). Echocardiography showed a large right atrial tumor. We performed urgent surgery to prevent a tumor embolism. As the tumor was firmly attached to the atrium, septum and ascending aorta, we performed partial resection to improve the patient’s hemodynamics status. Pathologic findings showed DLBCL. Systemic chemotherapy induced partial remission with out any cardiac recurrence.
