We present a case of chondrosarcoma of the hyoid bone, a rare condition with only 17 cases reported in the English literature. A 71-year-old woman whose only symptom was a painless mass in the upper right neck was diagnosed with lymph node metastasis from endometrial stromal uterine sarcoma based on her medical history and fine-needle aspiration cytology (FNAC) results. We resected the tumor in modified radical neck dissection with right hemihyoidectomy. The final histological diagnosis was grade 2 chondrosarcoma. No evidence of recurrence has been seen in the 21 months after surgery, but long-term follow-up is essential because recurrence has been reported even after five years. We discuss the clinical characteristics and management including diagnosis and treatment and review the literature of this rare tumor.
