Abstract
Thyroid cancers are a rare condition; of these, differentiated thyroid carcinomas are the most common and have a good prognosis with timely diagnosis and treatment. In the case of a late diagnosis, these carcinomas can breach the thyroid capsule and invade the laryngo-tracheal axis. The surgical treatment of locally invasive papillary thyroid carcinoma is a complete resection with the preservation of laryngeal functions when it is possible. We report the case of an 80-year-old patient who presented with inspiratory dyspnea and hemoptysis showing endotracheal localization of a papillary carcinoma of the thyroid.
