Laryngeal chondrosarcoma is rare and accounts for 0.2% of all larynx malignancies. Although chondrosarcoma is the most common sarcoma seen in the larynx, laryngeal involvement by cartilage tumors is rare. In this article, we aimed to present the differential diagnosis of chondrosarcoma located in the thyroid cartilage, which is a rare site, in a 75-year-old male patient. The patient underwent total laryngectomy by the otolaryngology department. The macroscopy of the laryngectomy material sent to the pathology laboratory revealed a 3x2 cm tumor with a polypoid extension to the lumen from the bottom of the right vocal cord. Although clinical and radiological findings are important in the diagnosis, the definite diagnosis is based on the pathological examination. It is especially important to differentiate the lesion from chondromas.
喉软骨肉瘤罕见，占所有喉部恶性肿瘤的 0.2%。尽管软骨肉瘤是喉部最常见的肉瘤，但软骨肿瘤累及喉部的情况很少见。本文旨在通过耳鼻喉科对 75 岁男性患者行全喉切除术，介绍罕见部位——甲状软骨的软骨肉瘤的鉴别诊断。病理实验室送检的喉切除标本大体观察显示，右侧声带底部有一个 3x2cm 的肿瘤，向管腔呈息肉样延伸。虽然临床和影像学检查结果对诊断很重要，但明确诊断仍基于病理检查。从软骨瘤中鉴别该病变尤为重要。
