The characteristic features of chondroma and chondrosarcoma of the larynx (less than 1% of laryngeal tumors) are discussed in a case report. Laryngoscopy (rounded, smooth tumor, covered by normal mucous membrane) and HR-CT of the larynx (swelling of the cartilages, calcifications in 80% of cases) give a characteristic view of the tumor, so that, by synopsis of both, a definite diagnostic statement concerning the kind of tumor is possible. However, carcinoma of the larynx with invasion of the cartilage, laryngeal manifestation of multiple chondromatosis and calcification after severe trauma have to be differentiated from cartilaginous tumors of the larynx. The adequate therapy of chondroma and low-grade chondrosarcoma consists of partial laryngectomy and reconstruction of the air passages. High-grade chondrosarcoma should be treated with radical laryngectomy.
一份病例报告讨论了喉软骨瘤和软骨肉瘤的特征（占喉肿瘤的比例不到1%）。喉镜检查（圆形、表面光滑的肿瘤，被正常黏膜覆盖）和喉部高分辨率CT（软骨肿胀，80%的病例有钙化）可呈现肿瘤的特征性表现，因此，综合两者情况，有可能对肿瘤类型作出明确的诊断结论。然而，必须将侵犯软骨的喉癌、多发性软骨瘤病的喉部表现以及严重创伤后的钙化与喉软骨肿瘤相鉴别。软骨瘤和低度软骨肉瘤的适当治疗方法包括部分喉切除术和气道重建。高度软骨肉瘤应采用根治性喉切除术进行治疗。
