Myxoid Chondrosarcoma of the Hyoid Bone

Abstract

Introduction Chondrosarcoma of hyoid bone is very rare with only 19 cases still reported. We, therefore, present this case report for the interest of medical literature to make clinicians aware of the disease. Case Report They usually present as a slow growing upper neck mass. Computed tomography (CT) and magnetic resonance imaging (MRI) are useful radiologic investigations. The tumour was resected through a trans-cervical approach. Definite diagnosis was made by postoperative histopathology and immunohistochemistry. Discussion Surgical excision is the treatment of choice for local control. Incomplete removal is a risk factor for recurrence and possible dedifferentiation. Long term follow up is necessary.
