Abstract
Chondrosarcoma of the larynx is a rare disease, accounting for less than 1％ of all malignant tumors of the larynx. We report a case of chondrosarcoma of the larynx that originated in the cricoid cartilage, for which a total laryngectomy was performed. The patient was a 74-year-old male who came to our hospital with a chief complaint of dyspnea on exertion. Endoscopic examination of the larynx revealed a prominent lesion below the glottis. Furthermore, CT and MRI indicated a laryngeal chondrosarcoma with a primary origin in the cricoid cartilage. For diagnostic purposes, a direct laryngoscopic tumor reduction procedure was performed, however, it was difficult to distinguish chondrosarcoma from chondroma. The tumor grew slowly, and a total laryngectomy was eventually performed, with the final histopathological result leading to a diagnosis of chondrosarcoma Grade Ⅱ. In the treatment of laryngeal chondrosarcoma, not only cure but also function preservation must be considered. Additionally, the choice of surgical technique must be carefully considered.
