Cardiac swinging calcified amorphous tumors in end-stage renal failure patients.
We recently encountered 2 patients with mobile cardiac calcified amorphous tumors who were successfully treated by surgery. Both patients had mitral annular calcification and were on hemodialysis. These tumors showed swinging motion on echocardiography and they grew rapidly. Intraoperatively, the tumors were found to be fragile and they easily detached from their origin. The histologic findings were thrombus with angiogenesis, fibrin, and calcium deposition. This rapid-growing mobile tumor in end-stage renal failure patients is speculated to increase the risk of embolic events and should be included as a special entity of cardiac amorphous tumors.
