Thyroglossal duct cysts in the elderly.

An instance of thyroglossal duct cyst in a 68-year-old man was reported. The clinical diagnosis of a thyroglossal duct cyst is suggested by the presence of a cystic mass situated anteriorly in the midline of the neck regardless of the patient's age. A review of the literature revealed that the incidence markedly decreases with age, with the great preponderance of cases occurring in infancy and childhood. Fourteen cases of thyroglossal duct cyst have been reported in the over-60 population.
