title: Double thyroglossal duct cyst involving the floor of the mouth and sublingual gland region.
abstract: Thyroglossal duct cysts are the most common congenital neck masses that develop during childhood. The masses develop from remnants of thyroglossal ducts and typically appear as midline neck masses. Double thyroglossal cysts and the complete failure of the obliterative process of thyroglossal duct are very rare in the literature. This manuscript describes a rare case of double thyroglossal duct, localized above the geniohyoid muscles affecting the floor of the mouth region and sublingual gland. The diagnostic criteria of the tumor and surgical procedure are discussed. To our knowledge, only 3 similar cases were reported in the literature.
