Chondromas of the larynx are rare neoplasms; only a few examples of cartilaginous tumors affecting hyoid bone have been reported. A 33-year-old woman presented with a neck mass on the left carotid triangle. The patient's computed tomography and magnetic resonance imaging revealed a heterogenous mass, which seemed to originate from the left greater cornu of hyoid. The mass was excised using a transcervical approach with left greater cornu of hyoid bone. The pathologic diagnosis was chondroma of hyoid. Expert radiologic and pathologic review is mandatory in cartilaginous neoplasms of the larynx. Cartilaginous neoplasms of the hyoid should be included in the differential diagnosis of neck masses at the carotid triangle.
