title: Chondrosarcoma of sinonasal cavity: a case report and brief literature review.
abstract: BACKGROUND
  Chondrosarcomas are slow-growing malignant tumors that usually arise from cartilaginous structures. It may occur in the head and neck region with a predilection for the maxillofacial skeleton, where it has been reported to occur particularly in the mandible and maxilla. Chondrosarcoma of the sinonasal tract is very rare.
  
  
  OBJECTIVE
  Report a new case
  
  
  METHODS
  We present the case of a 43-year-old man presenting with an incidental finding of a chondrosarcoma of the maxillary and ethmoid sinus with nasal extension. The tumor was completely resected using a transnasal endoscopic approach. Treatment has followed by a radiation therapy and the patient was considered free of disease at her 5 years follow-up.
  
  
  CONCLUSIONS
  Surgery is the mainstay treatment of chondrosarcomas. In selected patients, complete resection can be achieved using transnasal endoscopic approach.
