Arytenoid chondroma

Abstract EN

Introduction.

To our knowledge, there is only one other reported case of arytenoid chondroma (1956).

Our case report highlights the diagnosis and management of this rare disorder.

Case report.

A 33-year-old woman presented with a two-month history of episodic severe dysphonia and shortness of breath.

On examination, she had left arytenoid fullness and left vocal fold hypomobility.

A magnetic resonance imaging (MRI) of the neck with and without gadolinium showed a mass arising from the left arytenoid with soft tissue swelling.

She underwent micro-direct laryngoscopy with excisional biopsy of the cartilaginous mass revealing chondroma without malignant changes.

Follow-up at one year showed no interval re-growth and resolution of her symptoms.

Conclusion.

Chondromas are benign and account for less than 1% of laryngeal tumors.

They usually arise from the cricoid cartilage.

Chondromas are usually small (< 2 to 3 cm) and occur in children and young adults, while chondrosarcomas frequently are larger and occur later in life.

It is important to distinguish between these two tumors through biopsy.

For chondromas, complete excision and close follow-up are recommended; chondromas have a high incidence of local recurrence.
