CONGENITAL lesions make up about 6% of all masses found within the neck.1 Approximately two thirds of these congenital abnormalities involve the thyroglossal duct in the form of cysts or sinuses. Despite the frequent occurrence of thyroglossal duct malformations, a familial pattern, to our knowledge, has not been described.

A healthy 1-year-old girl was admitted to the Denver General Hospital with a painless, midline cervical mass over the hyoid bone.

No cutaneous fistulous tract was noted.These findings were suggestive of a thyroglossal duct cyst. Surgical excision, using the Sistrunk technique,2 demonstrated a squamous cell-lined
