[All venous obstructions is not necessarily due to phlebitis. Case report of an ilio-femoral venous leiomyosarcoma].

Abstract

Venous leiomyosarcoma are rare malignant tumours that are usually revealed by an oedema of the lower limb, a sign of deep phlebitis. As the development is not linked with radiotherapy and chemotherapy, the prognosis depends mainly on a early diagnosis, which brings the best opportunities of complete surgical exeresis before the apparition of metastasis. The case reported below as well as ten other cases taken in the literature show the necessity to mention this diagnosis when confronted to any phlebitis appeared in the absence of usual precipitating factors. It is all the more necessary when mass is found by palpation, a small tumour is revealed by echography or when phlebography shows a lateral or circumferencial stricture that is different from usual pictures of phlebitis.
