The chondromas of laryngeal cartilage constitute less than 1% of common mesenchymal tumors of the larynx. 70-75% of chondroma is located at the endolaryngeal surface of the cricoid cartilage. Here is a case report of the chondroma of arytenoid cartilage-a rare site of occurrence. A middle aged male patient, presented to the outpatient department of otorhinolaryngology with a history of hoarseness of voice. On Flexible laryngoscopy [Pentax, Tokyo, Japan], the right vocal cord was found to be immobile along with a smooth bulge noted over the arytenoid cartilage. The computerized tomography scan of the neck showed a well-defined peripherally calcified lesion arising from the superior aspect of right arytenoid cartilage possibly chondroma. Patient underwent microlaryngeal surgery and sub mucosal excision of the arytenoid mass which was confirmed as chondroma on histopathological examination. High degree of suspicion is required while examining a patient with hoarseness of voice and one should have chondroma as one of the differential diagnosis.
喉软骨软骨瘤占喉部常见间叶组织肿瘤的比例不到1%。70%-75%的软骨瘤位于环状软骨的喉内表面。本文报告一例罕见的杓状软骨软骨瘤病例。一名中年男性患者因声音嘶哑病史就诊于耳鼻喉科门诊。在[日本东京宾得公司生产的]可弯曲喉镜检查中，发现右侧声带固定不动，杓状软骨上有一个光滑的隆起。颈部计算机断层扫描显示，右侧杓状软骨上缘有一个边界清晰、周边钙化的病变，可能为软骨瘤。患者接受了显微喉镜手术和杓状肿物的黏膜下切除术，组织病理学检查证实为软骨瘤。在检查声音嘶哑的患者时需要高度怀疑，软骨瘤应作为鉴别诊断之一。
