We report the case of a 62-year-old man with a Squamous cell carcinoma of the thyroid gland which had invaded the hypopharynx. Primary squamous cell carcinoma of the thyroid gland is extremely rare. Its clinical course is very aggressive and the prognosis is poor. The patient underwent a radical resection of the thyroid, hypopharynx, larynx and resection of the trachea and esophagus was conducted concomitantly with bilateral neck dissection. Reconstruction of the terminal tracheostomy in the anterior mediastinum was created using a pectoralis major muscle flap.
