[Endotracheal dystopia of thyroid tissue].
Endotracheal ectopic thyroid tissue is rare. It can cause gradual obstruction of the tracheal lumen culminating in sudden dyspnoea. The diagnosis is relatively easy to make with the aid of a laryngeal mirror, by endoscopy, or by x-rays. However, it is most important to take the clinical picture into consideration. It is thought that the ectopic tissue arises from splitting of the thyroid gland during the descent in the embryonal stage. Treatment consists of removal via a tracheofissure. The tracheal mucous membrane must be treated with special care to prevent cicatricial stenosis of the trachea.
