TUMORS of the inferior vena cava are a pathologic curiosity of extreme rarity. In 1950 Roussak and Heppleston,1 in England, reported a case of leiomyosarcoma of the inferior vena cava producing obstruction of the vessel. The tumor was found at autopsy. In an exhaustive review of the literature by these authors and ourselves only two cases of primary tumors of the inferior vena cava could be found, both of which were reported in the German literature in the past century. One, a spindle-cell sarcoma containing some smooth-muscle tissue, producing complete obstruction of the vein, was reported by Perl,2 in 1871. The other, an endothelioma in a one-year-old child, was reported by Unruh,3 in 1896. There have been no previously reported cases of leiomyosarcoma of the inferior vena cava removed at surgery with or without survival of the patient.
