title: [Synchronous osteochondroid hamartoma and squamous cell carcinoma of the larynx].
abstract: BACKGROUND
  Soft-tissue tumors of the larynx are rare, especially hamartomas. Fewer than a dozen well-documented cases have been described. We report the case of a 65 year-old man diagnosed of a synchronous epithelial tumor of the right vocal fold and a soft-tissue tumor of the contralateral lamina of the thyroid cartilage.
  
  
  METHODS
  CT scan revealed a low-attenuating, expansive mass involving the left ala of the thyroid cartilage without airway compromise airway. The lesion contained small, scattered calcifications and the mucosa was intact, suggesting a cartilaginous tumor. The patient underwent endoscopic resection of the right vocal fold tumor and subtotal resection of the left ala of the thyroid via median thyrotomy.
  
  
  RESULTS
  Pathology revealed a squamous-cell carcinoma of the vocal fold and an osteochondroid hamartoma within the thyroid cartilage. The management of patients with laryngeal lesions suggestive of a cartilaginous nature is discussed.
  
  
  CONCLUSIONS
  To our knowledge, this is the first case of a synchronous laryngeal hamartoma and carcinoma reported in the literature.
