Extensive thyroglossal duct cyst in 83-year-old patient.

Thyroglossal duct cysts (TDCs) are developmental cysts that occur in the neck. These lesions are usually encountered in the first decade of life; cases appear to be rare in elderly patients. Thirteen cases have been reported so far in patients over 70 years of age. Although the Sistrunk procedure remains the standard treatment, the management of TDCs continues to be a matter of controversy in some instances. We report the third case of extensive TDC published in patients over 80 years of age.
