Chondrosarcoma is a malignant tumor of cartilaginous origin, and the second most common primary malignant bone tumor, however, chondrosarcoma of the head and neck is relatively rare. Only 10％ of chondrosarcomas occur in the head and neck region, such as the skull base, maxilla mandible, and larynx. Chondrosarcoma of the hyoid bone is a very rare site of involvement. In the English literature to date, only 14 cases of chondrosarcoma of the hyoid bone have been reported.
We present a case of chondrosarcoma of the hyoid bone. The patient was a 69-year-old man who underwent surgical excision of the tumor via a transcervical approach. The resected tumor originating from the hyoid bone was a 4×4 cm encapsulated lesion. Histological examination demonstrated grade II chondrosarcoma. Five years after surgery, there is no any evidence of recurrence. Long-term follow-up is essential.
Key words :chondrosarcoma, hyoid bone
