Chondrosarcoma of the hyoid bone

We describe a case of a 73-year-old man with a chondrosarcoma of the hyoid bone. The patient presented with a painless palpable lump in the upper anterior cervical region that had been growing for over 10 months. Fine-needle aspiration cytology suggested pleomorphic adenoma but further imaging investigation with CT revealed an exophytic tumour originating from the body of the hyoid bone with prominent chondroid-like calcifications typical of a chondrosarcoma. Histopathology of the surgical specimen confirmed the diagnosis of a moderately differentiated chondrosarcoma. Chondrosarcomas account for 11% of all bone cancers, of which up to 12% are in the head and neck. Primary sites of the head and the neck include the skull base, the nasal cavity, the maxilla, the mandible and the larynx. Chondrosarcomas of the hyoid bone are exceptionally rare, with only 20 such cases previously reported in the English literature.

IntroductionA chondrosarcoma originating from the hyoid bone is very rare. Here, we describe a case of low-grade chondrosarcoma of hyoid origin and discuss its preoperative imaging features, including those on positron emission tomography-computed tomography, and its recurrence rate.Case presentationA 42-year-old Japanese man noticed a mass in the right submandibular region of his neck. A hard 3.0 × 2.8 cm tumor was noted on the right side of his hyoid bone. The mass was immobile and moved with deglutition.ConclusionEven though radiographic studies, including positron emission tomography-computed tomography, were inconclusive, the cartilaginous tumor was surgically removed en bloc, and the tumor was diagnosed based on the results of pathological investigations. Close follow-up is recommended in such cases due to the potential for recurrences, because local recurrence occurred in 50% of the reported cases of grade one chondrosarcomas.

“…The radiologic diagnosis of chondrosarcoma is primarily dependent on the tumor matrix mineralization and associated bone destruction. The mineralization is reflected radiographically as strips of calcium variously called crescentic, flocculent, punctate, or splotchy 1,2,4,8 . Successful eradication of chondrosarcoma depends on complete and wide excision.…”
