Abstract

CASES of primary intraluminal leiomyo-N sarcoma of the femoral vein have been reported to date.Tumors arising from vessel walls, however, have been reported in a few isolated cases.The purpose of this paper is to report an authentic case of a primary intrinsic sarcoma arising from the right femoral vein.CASE REP0R.rE.
