[Desmoid fibroma of the mandible. One case (author's transl)].

The authors report a case of desmoid fibroma of the mandible in a 75-years-old woman. This benign bone tumour, described for the first time by Jaffe in 1958, would seem to be rare in this site. Sixteen other cases have been found in the literature. The diagnosis is based upon histological examination of the operative specimen.
