title: [Solitary naso-sinusal fibrous tumor].
abstract: Here we present two clinical cases of solitary naso-sinusal fibrous tumour. This tumour has a mesenchymal origin and has an evident pleural location, with well defined immunohistochemical and ultrastructural characteristics. The clinical manifestation is an apparent benign tumour with an inclination to local aggressiveness. The most effective treatment seems to be surgical removal, but given the low number of cases mentioned (there are only eight cases reported in international literature), and the tendency to eventual recurrence, called for cobalt therapy after surgery. The evolution of clinical cases is irregular.
