European archives of medical research(2022)
Abstract
Ectopic thyroid tissue (ETT) is a rare and usually asymptomatic congenital anomaly.The most common presentation is midline ectopic thyroid.In this case, a 55-year-old female treated for asthma due to dyspnea was diagnosed with stridor on physical examination.Mass that nearly obliterated the lumen of the trachea was observed on thoracic computed tomography.Diagnostic and therapeutic rigid bronchoscopy were performed.The pathological result of the biopsy was ETT.Ectopic intratracheal thyroid tissue is a rare cause of upper respiratory tract obstruction.
