A parosteal chondrosarcoma with low-grade malignancy attached to the hyoid bone in a 66-year-old man is reported. The tumor was considered to present a low-grade malignancy because slight invasion into the surrounding soft tissues and rapid growth were observed. Four years after initial surgery he had a local recurrence. To the best of our knowledge, this is the first reported case of parosteal chondrosarcoma in this location.
