title: Primary leiomyosarcoma of the great saphenous vein: case report.
abstract: OBJECTIVE
  To describe a case of primary leiomyosarcoma of the great saphenous vein.
  
  
  METHODS
  A 59-year-old Chinese lady presented with two painful lumps in the right thigh in the line of the great saphenous vein. At surgery, in September 2004, two tumors in the right great saphenous vein above the knee were excised with the intervening normal vein. Histopathological studies confirmed both masses as leiomyosarcoma. Radiotherapy was given postoperatively. The patient has been followed-up for 300 days after surgery with no evidence of local or distant metastasis.
  
  
  CONCLUSIONS
  Leiomyosarcoma of the great saphenous vein can exist at more than one site. Tumor resection and radiotherapy was associated with good patient prognosis.
