There have been fourteen cases of solitary fibrous tumour reported as originating from the paranasal sinuses. Here we report a case of solitary fibrous tumour that involved the right nasal cavity with extension into the oropharynx causing stertor and intermittent respiratory obtruction. Histopathology examination revealed the tumuor cells expressed CD34 turnout marker.
Seventeen cases are reported of desmoplastic variant of ameloblastoma of the jaws observed during the years 1967-1991. There were 12 females and 5 males, and these consisted of 7 Chinese, 6 Malays, 2 Indians, 1 Sikh and 1 Kadazan. Their ages at diagnosis ranged from 21-60 years with a mean of 36.6 years. There were 10 mandibular and 7 maxillary tumours. Of these, 14 cases involved the anterior segment with extension to the premolar region in 5 cases. 60% of cases were radiologically suggestive of fibro-osseous lesions. The main mode of treatment was resection and 1 case presented with recurrence. The findings of this study were compared with those of previous reports.
