title: Desmoplastic fibroma involving the mandible.
abstract: Desmoplastic fibroma is a rare, benign, fibroblastic tumour arising intra-osseously. A case in a 13 year-old male is described. A tumour, situated between the roots of the right mandibular canine and premolar, was excised in 1984. Morphologically, the characteristics of the tumour conformed well to those of a desmoplastic fibroma. The differential diagnosis of desmoplastic fibroma with reference to the histopathological and ultrastructural appearance of the tumour is discussed.
