Intravenous leiomyomatosis is a rare disease entity of benign smooth muscle invading into the lumen of veins. We describe a case of intravenous leiomyomatosis originating from the uterus, growing in the inferior vena cava, and extending into the right ventricle association with multiple pulmonary metastasis. A 53-year-old woman with chest discomfort and several times attacks of syncope was treated at our hospital. The tumor was successfully removed with moderate hypothermic cardiopulmonary bypass after total hysterectomy with a bilateral salphingo-oophorectomy, and multiple pulmonary metastasis under simultaneous sternotomy and laparotomy was confirmed.

Epithelioid hemangioendothelioma (HE) is a very rare malignant tumor that is pathologically benign tumor originating from endothelial cell but clinically presents metastasis and recurrence. A 29-year-old asymptomatic man, preoperatively diagnosed as lung cancer in the left lower lung, underwent a lobectomy, a wedge lung resection of left upper lung, and partial resection of diaphragm. Left lower lobar lesion was confirmed as pulmonary epithelioid hemangioendothelioma, but the lesions of the left upper lung and diaphragm were remained calcified by spontaneous regression of HE. We report a case of subcutaneous metastasis that occurred two times at 10 months and 19 months after previous surgical treatment of pulmonary EH.
