ENT · Larynx: laryngeal chondrosarcoma site

Sample item

A slowly enlarging submucosal mass is seen below the glottis on the posterior wall of the larynx with calcification on CT. Which tumour most commonly arises at this site?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Chondrosarcoma from the posterior lamina of the cricoid cartilage

Chondrosarcoma is the most common non-epithelial malignant laryngeal tumour and arises mostly from the cricoid, particularly the posterior lamina, with stippled calcification. It is slow growing and managed by conservative surgery, with total laryngectomy needed for extensive disease.

Option by option

  • A. Vocal nodule

    Nodules are bilateral vocal fold lesions.

  • B. Chondrosarcoma from the posterior lamina of the cricoid cartilage (correct)

    Correct. The cricoid lamina is the usual origin.

  • C. Squamous carcinoma of the vocal cord

    Squamous carcinoma arises from surface epithelium and is not calcified.

  • D. Laryngeal papilloma

    Papillomas are exophytic and mucosal.
