Thyroglossal duct may persist anywhere along the descent from the tongue to the thyroid. Lingually localized thyroglossal duct cysts are congenital lesions of the pharynx, which are very uncommon and may cause morbidity and mortality if not treated expeditiously. Double thyroglossal cysts and the complete failure of the obliterative process of thyroglossal duct are very rare in the literature. In this article, we describe a case of two cysts derived from the same thyroglossal duct, one in the hyoid region and the other in the tongue base. To our knowledge, this coexistence has not been described previously in the literature.YorgancılarEdizEDepartment of Otolaryngology, Medicine Faculty of Dicle University, Diyarbakır, Turkey. edzyrg@hotmail.comYıldırımMüzeyyenMGünRamazanRBüyükbayramHüseyinHTopçuIsmailIengCase ReportsJournal Article
