Abstract：
Chondrosarcoma of the thyroid cartilage is a sporadic disease with nonspecific clinical presentation. Smooth swelling of the supraglottic area should arouse suspicion of possible pathology. In addition to laryngoceles, which usually do not have a significant impact, otolaryngologists should consider chondrosarcoma of the thyroid cartilage and indicate computed tomography (CT). Late diagnosis leads to worse prognosis, particularly worse voice after more extensive surgery, need for tracheostomy, and worse survival from higher degree chondrosarcomas.
摘要：
甲状软骨软骨肉瘤是一种散发性疾病，具有非特异性临床表现。声门上区域的光滑肿胀应引起对可能病理的怀疑。除了喉癌,通常不会产生重大影响，耳鼻喉科医师应考虑甲状腺软骨软骨肉瘤，并提示计算机断层扫描（CT）。晚期诊断会导致预后恶化，尤其是在更广泛的手术后声音更差，需要气管造口术，更严重的软骨肉瘤的存活率。
