title: Laryngeal chondrosarcoma: report of two cases.
abstract: OBJECTIVE
  The present study describes the clinical, radiological and histological features of laryngeal chondrosarcoma, on the basis of two clinical cases, and discusses management.
  
  
  METHODS
  Two male patients, aged 63 and 51 years, presented with low-grade chondrosarcoma revealed respectively by a mass in the lateral neck and by laryngeal dyspnea. CT showed a tumoral process with calcification, developed from the thyroid and cricoid cartilage, respectively. The first patient underwent partial and the second total laryngectomy.
  
  
  CONCLUSIONS
  Chondrosarcoma is diagnosed on the basis of combined clinical, radiological and histological signs. Differential diagnosis with chondroma may be difficult, especially in grade-1 chondrosarcoma.
  
  
  CONCLUSIONS
  Laryngeal chondrosarcoma is a rare tumor. Management is basically surgical. Prognosis is generally good, depending essentially on histologic grade.
