An unusual case of laryngeal carcinoma

A 62-year-old male patient presented with carcinoma of the larynx which behaved in an atypical fashion clinically. It increased in size rapidly within a period of 5 weeks and clinically presented as a dumbell-shaped neck swelling over the thyroid alae. It had features on plain x-ray, tomography and CT scan which led to the diagnosis of chondrosarcoma of the larynx. After total laryngectomy, it turned out to be a squamous cell carcinoma of the larynx with some unusual histopathological features including bone formation in the tumour.
