[A recurrent desmoid tumor of the popliteal fossa with vascular compromise].

We report a case of a 18-year-old male patient with his fourth relapse of a desmoid tumour of the left popliteal hollow after a traumatism in this area. Arterial displacement and extrinsic compression were showed by arteriography. Tumoration was extirpated including popliteal artery, in this way a terminal by-pass from distal femoral to peroneo-tibial trunks with contralateral great saphena was made. Diagnosis of intestinal polyposis and of the little osseous malformations, was discarded these pathologies frequently are related with these tumours. The research for 8 years and 4 months doesn't show any relapse, nor local neither multicentral. Furthermore, some considerations about this theme are reported.
