[Intravenous leiomyomatosis with cardiac extension in an elderly woman: report of a case].
Intravenous leiomyomatosis is a histologically benign smooth-muscle tumor arising from either a uterine myoma or the wall of a uterine vessel with extension into veins. We describe a 71-year-old woman with a prior history of subtotal hysterectomy for uterine myoma years earlier who presented with palpitation. Echocardiographic examination revealed an intracardiac mass protruding into the right ventricle during diastole. The caval tumor could be traced to the right renal vein by magnetic resonance image. She was operated on for intracardiac and intracaval leiomyomatosis. The intracaval tumor proved to be not totally resectable. Presence of smooth muscle was confirmed by smooth muscle actin and desmin positive cells in the tumor. Tumor cells also proved to possess estrogen receptors. The patient has been closely followed-up with antiestrogen therapy.
