Great Saphenous Vein and Leiomyosarcoma

IntroductionThe authors report a rare case of a leiomyosarcoma of the great saphenous vein (GSV), diagnosed in a 72-year-old male.ReportThe symptoms were limited to leg tension and pain during exercise; Duplex scan suggested a GSV thrombosis with an enlarged lymph node. The failure of low-molecular-weight heparin treatment requested a magnetic resonance imaging (MRI) scan revealing a mass attached to the left saphenous vein.An en bloc removal of the mass, measuring 5.5 cm in diameter, and a wide resection was performed; a further revision was necessary after 2 months in order to perform radical surgery and the patient underwent radiation therapy. When lung metastases occurred, the patient started chemotherapy but after 5 months died.DiscussionLeiomyosarcoma is difficult to diagnose, requiring MRI scan or positron emission tomography-computed tomography (PET-CT) scan. The best therapy is surgery, which must be radical and may be followed by radiation therapy that may be indicated postoperatively in case of metastases
