ABSTRACT
Benign laryngeal cysts represent a rare group, generally about 5%, of benign laryngeal lesions. The clinical presentations of benign laryngeal cysts can vary from being asymptomatic to severe symptoms, such as rapid onset epiglottitis, dyspnea, stridor, and signs of respiratory obstruction depending on the location and extension of the cyst. We report a 68-year-old male patient presented to our clinic with a 6-month history of progressive anterior cystic neck swelling, which moved on swallowing. He was asymptomatic otherwise. Thyroid profile was normal and computed tomography (CT) neck contrasted revealed a mass at the posterior part of the hyoid bone insinuating into visceral space between the thyroid cartilage extending toward the anterior neck inferior and the thyroid cartilage mimicking a thyroglossal duct cyst. Sistrunk procedure was performed and histopathological examination revealed a benign laryngeal cyst. There were no post-operative complications and no evidence of malignancy. The patient was followed up after 10 months with no recurrence. This article’s objective is to emphasize on the importance of considering few other possible differentials in the anterior neck cystic swelling in adults with no conclusive evidence during investigations as well as to discuss its management.
Key words: Benign laryngeal cyst, adult thyroglossal duct cyst, thyroglossal duct cyst, cyst in larynx, adult anterior neck swelling.
