A Case of Highly Located Thyroglossal Duct Cyst

Congenital anterior neck masses comprise a rare group of lesions that are frequently found in children. The most frequent abnormalities are ectopic thyroid tissue and malformations of the thyroglossal duct, particularly the thyroglossal duct cyst.

The most frequent congenital neck mass is a thyroglossal duct cyst (TGDC), which frequently manifests in young patients as a painless lump in the middle of the neck. When an adult develops a lateralized neck lump for the first time, it may raise more concern for malignancy.

A thyroglossal duct cyst is usually suspected based on clinical examination, imaging can confirm the diagnosis, assess the extent, and evaluate for associated complications. We report the case of a sixty years old female patient presenting with a submental swelling, suspected to be a laryngocele initially. Surgery and histology revealed a giant and high located thyroglossal duct cyst.
