Chondrosarcomas represent a group of malignant tumours composed of cells producing cartilage, and clear cell chondrosarcomas (CCC) represent a variant of these. A rare case of a laryngeal CCC is presented. The patient was a 70-year-old man who presented with a 6-week history of throat pain, worsening dysphonia and a lump in the neck. Examination revealed a level 3 neck mass and positron emission tomography imaging revealed a metabolically active right laryngeal mass. Biopsies revealed a cartilaginous neoplasm. The patient underwent total laryngectomy, and the pathology confirmed CCC of the larynx. Chondrosarcomas are the most common type of sarcoma in the larynx but the CCC variant is rare. CCC are usually low-grade tumours affecting long bones, with a male predominance. Less than six cases have been described in the literature affecting the larynx. Management of these malignancies is complete surgical excision given the high risk of local recurrence.
软骨肉瘤是一组由产生软骨的细胞组成的恶性肿瘤,透明细胞软骨肉瘤(CCC)是其中的一种变体。本文报告了1例罕见的喉CCC病例。患者为一名70岁男性,有6周咽痛、声音嘶哑加重及颈部肿块的病史。检查发现3区颈部肿块,正电子发射断层扫描成像显示右侧喉部有代谢活跃的肿块。活检显示为软骨肿瘤。患者接受了全喉切除术,病理证实为喉CCC。软骨肉瘤是喉部最常见的肉瘤类型,但CCC变体罕见。CCC通常是影响长骨的低级别肿瘤,男性居多。文献中描述的累及喉部的病例少于6例。鉴于局部复发风险高,这些恶性肿瘤的治疗方法是完整的手术切除。
