Introduction: Thyroglossal duct cysts are the most common congenital neck cysts .About 50% of the cases are detected within the first 2 decades of life, but can also appear later in adult life. Case report: This is a 57-year-old male patient followed for urothelial bladder carcinoma with a cervical mass that has been evolving for more than 20 years without signs of compression of adjacent organs. The examination noted a large anterior cervical swelling 16 cm in diameter, of firm consistency, painless and motionless on swallowing, the skin opposite the mass is healthy. The CT appearance is suggestive of a Thyroglossal Duct Cyst or a laryngocele. Exploratory cervicotomy found a superficial cystic mass, adherent to the body of the hyoid bone, strongly suspecting the possibility of a Thyroglossal Duct Cyst. The surgical excision was performed using the Sistrunk technique, removing the cyst en bloc with the body of the hyoid bone. And sent the specimen for histopathological evaluation, which confirmed per-operative diagnosis. Conclusion: The cyst of the thyroglossal tract is a common pathology in children, but remains rare in adults. The challenge of treatment is to know how to think about it in front of a cervical mass.
