Definition


During fetal development, the thyroglossal duct moves to form the thyroid. Sometimes a piece of this channel remains detached which will cause a thyroglossal duct cyst. Appearing early in life, it is often found in children or young adults. Its discovery can be made by palpation of a lump in the neck, and confirmed by performing a cervical ultrasound. This cyst presents risks of infection sometimes chronic and can rarely be carcinogenic, in which case it is removed by surgery.
