Primary Leiomyosarcoma of the Great Saphenous Vein: Case Report and Review of the Literature

Abstract

Soft tissue sarcomas are very rare tumors, representing less than 1% of all cancers. Leiomyosarcomas are a rare group of them representing about 6% of soft tissue sarcomas and they involve smooth muscles. Less than 2% of all leiomyosarcomas involves large blood vessels. Leiomyosarcomas of vein tunica media are very rare (1/100,000 malignant cancers) and only 10% of these originate from the great saphenous vein. In this article, we report a clinical case that occurred in our institution and review all the literature available at now.
