title: Malignant triton tumour of right paranasal sinuses: case report.
abstract: OBJECTIVE
  We report an extremely rare case of malignant triton tumour.
  
  
  METHODS
  Case report and review of the world literature concerning malignant triton tumour and heredity.
  
  
  RESULTS
  We present the case of a 47-year-old woman who underwent a lateral rhinotomy surgical resection of a malignant triton tumour of the right paranasal sinuses, a rare location for this tumour. Thereafter, she received adjuvant radiotherapy. The prognosis for this group of tumours is poor. Radical surgical excision of the tumour followed by radiation therapy must be the treatment of choice.
  
  
  CONCLUSIONS
  To our knowledge, this is a rare report in the world literature of malignant triton tumour. This case indicates that malignant triton tumour of the paranasal sinuses is a rare disease which otolaryngologists should be aware of, and one which should be included in the differential diagnosis of malignant lesions involving the sinonasal tract.
