title: Solitary fibrous tumours of the lower gingiva: a case report.
abstract: Solitary fibrous tumours (SFTs) are rare lesions in the oral cavity. Typically they arise in the pleura. We report a lesion occurring in the lower anterior gingiva. In histochemical examination, the spindle-shaped, neoplastic cells stained strongly for CD34 antigen and vimentin, but did not stain for desmin, smooth-muscle actin, muscle actin and S-100 protein. The expression of CD34 antigen and vimentin were useful for the differential diagnosis.
