Primary Malignant Cardiac Tumor Presenting with Dyspnea: A Case Report

Primary malignant cardiac tumors are rare tumors of the heart with a very poor prognosis. Complete excision is the treatment of choice, but it is dependent on the stage and extension of the tumor. We describe an old man with the initial presenting symptoms of progressive dyspnea. Our assessment revealed moderate pericardial effusion and a large infiltrative right ventricular mass. The initial differential diagnosis included malignant sarcoma, lymphoma, or melanoma. The patient underwent palliative excision of the tumor and chemotherapy. After biopsy, cardiac lymphoma was confirmed.
