Background: Thyroglossal duct cyst carcinoma is a rare entity.
A thyroglossal duct cyst nearly always arises in the midline of the neck.
Burkart et al studied 16 children (mean age: 3 yr) with a lingual thyroglossal duct cyst (LTGDC) and reported that most of these cysts were found incidentally, although the range of presentations varied from mild discomfort at the base of the tongue to cyanosis, labored breathing, and respiratory distress.
Other neck masses in the differential include thyroglossal duct cysts, cystic teratomas, thyroid or parathyroid lesions, lymphoproliferative disorders, reactive adenopathy, and vascular tumors.
Other diagnoses to consider when presented with a lateral neck mass include but are not limited to thyroglossal duct cyst, cystic hygroma, lymphadenopathy, lipoma, hemangioma, lymphoma, dermoid tumor, and carotid body tumor.
In addition, it is the imaging modality of choice in children with suspected thyroglossal duct cyst, not only to prove the cystic nature of the midline neck mass but also to confirm the presence of a normalappearing bi-lobed thyroid gland in the lower neck.
Diaz-Perez et al[5] have suggested that the mucinous thyroid tumor they described could have originated from thyroglossal vestiges, because thyroglossal cysts or sinus are lined by ciliated pseudostratified respiratory type cells, squamous cells, and mucus-secreting columnar cells.
