Abstract
BACKGROUND
Chondrosarcomas of the larynx are malignant tumours that most commonly originate from the hyaline cartilage. Chondrosarcoma of the larynx, the most common type of low-grade tumour, accounts for 1% of all laryngeal neoplasms.
CASE SUMMARY
We present the case of a 60-year-old female patient who developed progressive hoarseness and shortness of breath over a 2-mo period. The patient had undergone resection of a laryngeal tumour 14 years before the aforementioned symptoms occurred, and histopathological analysis indicated that it was a chondroma. During the assessment of the patient, a submucosal, oval-shaped tumour was detected that was predominantly located on the left side of the larynx and was approximately 6 cm in size. The decision to perform left partial vertical laryngectomy was made. A pathohistological diagnosis of low-grade chondrosarcoma was made. Considering the results of pathohistological analysis and the positive margins of the resection, a total laryngectomy was performed. During the 12-mo follow-up, no local relapse or regional or distant metastases was detected.
CONCLUSION
Chondrosarcoma of the larynx must be considered in the differential diagnosis of laryngeal submucosal tumours. It is crucial to carefully sample of tumour tissue, differentiate chondroma and chondrosarcoma, and consider the possibility of malignant changes from chondroma to chondrosarcoma.
Core Tip: Chondrosarcomas (ChSs) of the larynx are malignant tumours with a mesenchymal origin that most commonly originate from the hyaline cartilage. Although high-grade ChS of the larynx has also been described, low-grade tumours are the most common form of this disease. They are much more common in Caucasians and the men. This case highlights the utmost importance of recognizing mesenchymal tumours, especially those with a cartilage origin, during differential diagnosis in cases of intramural pathological processes in the laryngeal wall with a preserved mucosa, as these tumours are rare. It is crucial to carefully sample the tumour tissue, differentiate chondroma and chondrosarcoma, and consider the possibility of malignant changes from chondroma to chondrosarcoma.
