Spot diagnosis case 9

Scenario: This 56-year-old female with a history of COVID-19 pneumonitis and ICU admission visits the ENT outpatient clinic with a chronic cough and shortness of breath on exertion. Flexible laryngoscopy doesn’t show any abnormalities and there is normal vocal cord movement. There are some interesting findings on flexible tracheobronchoscopy.  


1) What is the likely diagnosis?
2) What evidence of previous treatment do you see?


Spot diagnosis case 8 is now closed.

Scenario: This 65-year-old gentleman with a history of reflux disease presented with a sore throat, dysphonia and progressive shortness of breath over the past year.  He’s a never smoker. CT showed a mixed density mass in the subglottis with ‘popcorn’ calcifications and there is no invasion to adjacent soft tissue or bone. Pathology shows granular calcifications in multinucleated chondrocytes.


  1. What is the likely diagnosis? – Answer: low grade chondrosarcoma
  2. What treatment would you recommend, and what are your considerations regarding treatment? – Answer: conservative if asymptomatic, endoscopic laser debulking if symptomatic, laryngectomy is reserved for large tumours in which surgery would cause destabilisation of the cricoid.
