Chondroma of the laryngeal cartilage is a rare, benign neoplasm which can manifest as a neck mass or, if situated within the airway, as slowly progressive obstruction, hoarseness or dyspnea. The most common location for chondroma is the posterior lamina of the cricoid cartilage; the next most common locations are the thyroid, arytenoid and epiglottic cartilages. Chondroma and low-grade chondrosarcoma are difficult to distinguish from one another histologically. Although chondrosarcoma reportedly recurs, local surgical excision without radical margins and with long-term clinical follow-up is recommended. We report one case of thyroid cartilage chondroma and include a review of radiologic studies and histopathologic analysis results. We also report a second case with severe airway obstruction caused by a large cricoid chondroma. A review of the English language biomedical literature on laryngeal chondroma is included.
喉软骨软骨瘤是一种罕见的良性肿瘤，可表现为颈部肿块，或若位于气道内，则表现为缓慢进展的梗阻、声音嘶哑或呼吸困难。软骨瘤最常见的部位是环状软骨后板；其次常见的部位是甲状腺、杓状软骨和会厌软骨。软骨瘤和低度软骨肉瘤在组织学上难以相互区分。尽管据报道软骨肉瘤会复发，但建议进行局部手术切除，无需根治性切缘，并进行长期临床随访。我们报告1例甲状软骨软骨瘤病例，并对放射学研究和组织病理学分析结果进行综述。我们还报告了第2例因巨大环状软骨软骨瘤导致严重气道梗阻的病例。本文还对英文生物医学文献中关于喉软骨瘤的内容进行了综述。
