Heart Osteosarcoma Presenting as Infective Endocarditis: A Case Report of a Patient With a Cardiac Pacemaker and Triple Malignancies

摘要

Primary and metastatic cardiac sarcomas represent rare neoplasms with a variable clinical course. We present a rare case of an 84-year-old man with a cardiac pacemaker and heart osteosarcoma, hepatocellular and prostatic carcinoma, who was admitted with suspected symptoms of infective endocarditis. Findings of cardiac osteosarcoma in a patient with a pacemaker and three malignancies have not been reported before in the literature.
