[A case of primary cardiac angiosarcoma associated with cardiac tamponade].

A 72-year-old man came to our hospital due to edema, malaise, and poor appetite in May 200X. He was diagnosed as cardiac tamponade, and open surgery revealed tumors in the right atrium and the left ventricule. Tumor tissue was revealed to be angiosarcoma by the pathological findings. Metastases to the brain, lungs, liver, and adrenal glands were found. The patient was treated with interleukin-2(IL-2)for 7 weeks. However, there was no anti-tumor effect, and the patient died in September, 200X. We reported a very rare case of cardiac angiosarcoma associated with cardiac tamponade, who was treated with IL-2 monotherapy.
