Key result
A case of recurrent tracheal paraganglioma presented with acute airway obstruction and hemorrhage following an initial misdiagnosis and treatment as medullary thyroid carcinoma.
Case Report (n=1)
Highlights the importance of accurate microscopic and immunohistochemical analysis to differentiate rare tracheal paragangliomas from medullary thyroid carcinoma to prevent misdiagnosis and severe complications like airway obstruction.
Emphasizes diagnostic vigilance in tracheal masses to avert obstruction; Level 5 case leaves open standardized IHC protocols and management.
Paragangliomas of the larynx are rare lesions that are often confused with other primary and secondary laryngeal neoplasms. Location in the subglottis is exceptionally rare. These lesions are often misinterpreted as medullary thyroid carcinoma (MTC). Accurate microscopic and immunohistochemical analysis combined with clinical and radiographic examinations are critical for proper diagnosis. In this report, we describe a case of a recurrent tracheal paraganglioma presenting with acute airway obstruction and hemorrhage following original misdiagnosis and treatment as MTC.
