OBJECTIVE
We report a case of cricoid chondroma, underlining the difficulty in establishing a precise differential diagnosis between chondroma and low-grade chondrosarcoma of the larynx.
MATERIAL AND METHODS
A 48-year-old woman developed inspiratory dyspnea. The final diagnosis was cricoid chondroma. We reviewed our case and data in the literature on these cartilaginous tumors.
RESULTS
The patient was treated with conservative surgery. At 18 months follow-up, no recurrence has been detected.
DISCUSSION
These tumors are rarely found in an ENT location and have similar histological features. According to many authors, the clinical course alone enables a distinction between chondroma and low-grade chondrosarcoma. Surgical treatment is indicated and provides good phonatory function in the vast majority of the cases.
目的
我们报告一例环状软骨瘤病例，强调在喉软骨瘤和低级别软骨肉瘤之间进行精确鉴别诊断存在困难。
材料与方法
一名48岁女性出现吸气性呼吸困难。最终诊断为环状软骨瘤。我们回顾了本病例以及文献中关于这些软骨肿瘤的数据。
结果
患者接受了保守手术治疗。随访18个月时，未发现复发。
讨论
这些肿瘤在耳鼻喉部位很少见，且具有相似的组织学特征。许多作者认为，仅凭临床病程就能区分软骨瘤和低级别软骨肉瘤。手术治疗是必要的，并且在绝大多数病例中能提供良好的发声功能。
