Congenital duplication of the larynx.

INTRODUCTION

The larynx is an intricate structure serving three important functions in humans: it protects the lower respiratory airway, facilitates respiration and helps produce sound through a key role in phonation.

OBJECTIVE

We report the first published finding of congenital duplication of the larynx in a patient with previously cleared squamous cell carcinoma of the neck and a new diagnosis of squamous cell carcinoma of the lung.

CASE REPORT: We describe the incidental finding of duplication of the larynx in a 62-year-old man with previously completely cleared squamous cell carcinoma of the neck, who presented with worsening dyspnoea. We also provide a brief overview of other published cases in which duplication of the vocal folds and epiglottis has been reported.

RESULTS

Our patient experienced no symptoms related to this incidental finding of congenital duplication of the larynx.

CONCLUSION

The first case of congenital duplication of the larynx is currently of academic interest only; however, the possible association with squamous cell carcinoma is postulated to raise awareness in clinicians who may observe further cases in the future.
