title: Multicentric extraabdominal desmoid tumour: a case report.
abstract: The very rare condition of multicentric desmoid tumours involving two distant and apparently independent sites is reported in a 17-year-old man. The tumours grew simultaneously and reached approximately equal size. No evidence of familiar polyposis or any other feature of Gardner's syndrome were noted. The proximal desmoid tumour developed from the left hip region and extended into the femoral bone, whereas the distal mass was attached to the left popliteal fossa infiltrating the flexor muscles, the nerves and vessels. On the basis of the good results published recently in the literature and our own earlier experiences, the intralesional resection of the desmoid tumours was completed with postoperative fractionated radiotherapy.
