We report a rare case of primary cardiac lymphoma in the right atrium. An 85-year-old woman with severe heart failure was referred to our hospital. The echocardiography revealed a huge tumor occupying the right atrial cavity. We conducted an emergency operation to resect the tumor. However, as the tumor strongly adhered to the wall of the right atrium and tricuspid valve, we performed partial resection of the tumor to improve hemodynamics. The pathological examination of the tumor was consistent with malignant lymphoma of B-cell origin. Although the postoperative chemotherapy was effective to reduce a volume of the tumor, the patient died because of the adverse reaction to medication.
