Simultaneous thyroglossal duct cyst with parathyroid cyst - a case report

Thyroglossal duct cysts (TDC) are common congenital deformities of the neck in children. Most of them are cysts formed by the thyroglossal ducts that do not disappear and degenerate in the early embryonic stage, and some residual structures are formed [1] . TDC exists alone and is rarely complicated by other congenital embryonic malformations. Only a few reports of TDC with branchial cleft cysts, thyroid cancer, thyroid hematoma, and epidermoid cysts have been reported [2-5] . However, the patient coexisted with TDC and parathyroid cyst (PC), a rare disease that has never been reported in the weapons literature. Therefore, we report a patient with a simultaneous TDC and a PC to explore the correlation between the two congenital anomalies.
