Myxoid chondrosarcoma of the cricoid cartilage

Primary cartilaginous bone tumors of the laryngeal region are extremely rare. Laryngeal chondrosarcomas account for 0.07–2% of all laryngeal neoplasms and less than 1% of all sarcomas.A 95% of all laryngeal chondrosarcomas are low-grade and are often underdiagnosed as benign chondromata. Biopsy is the cornerstone of the diagnosis. For definitive treatment there is a general consensus that conservative surgery is the most appropriate method. These tumors are known for their indolent course, low metastatic potential and high percentage of recurrence. The clinical outcome was the worse for patients with myxoid type of tumors, regardless of tumor grade or applied form of therapy. A 65-year-old man with no family history of malignant or hereditary diseases and a 50-year history of smoking 20 cigarettes a day presented with a 7-month history of breathy dysphonia.
