[Desmoid fibroma of soft tissues of extra-abdominal sites: review of the literature apropos of a case located at the posterior face of the thigh].

The authors report a case of desmoid fibroma on the posterior surface of the thigh in a woman during the post-partum period. This is a rare site for this tumour. CT scan combined with MRI appears to be useful for diagnosis. Treatment is strictly surgical, but depends on the histological benign nature and the local malignancy. Surgery is generally conservative with risks of recurrence and occasionally amputation is necessary.
