Leiomyoma of the femoral vein: a case report and review of the literature.

Leiomyomas are benign smooth muscle tumors. A leiomyoma originating from the vein is rare. We describe a primary femoral vein tumor that was diagnosed as an unusual leiomyoma in a 50-year-old woman. It was the first reported leiomyoma in the femoral vein in English studies. We have reviewed the studies on leiomyoma from the blood vessel and summarized their characteristics, therapies, and prognosis.
