Primary tumor of the vena cava inferior occurs rarely. This is indicated by the fact that in the examination of the records of 34,000 autopsies in the department of pathology of the University of Minnesota not a single report of its occurrence was encountered. Furthermore, a thorough search of the literature revealed the reports of only 4 cases.
The purpose of this paper is to report the occurrence of a leiomyosarcoma arising from and completely occluding the subdiaphragmatic portion of the inferior vena cava. The clinical and the postmortem observations in this case constitute the basis of the present study. From a diagnostic point of view the clinical picture was that of Chiari's disease (endophlebitis obliterans hepatica), except for certain vascular signs simulating those of constrictive pericarditis.
