Intralaryngeal ectopic thyroid

Abstract

Lingual thyroid is the most common presentation of ectopic thyroid tissue. In contrast, to that laryngeal location is extremely rare. We report a case of 59 years old woman with a history of progressive dyspnea and nodular thyroid goiter. Endoscopic examination revealed subglottic smooth tumor of the right side of the larynx. CT scans revealed mass localized in infraglottic part of the larynx, causing infraglottic stenosis. The biopsy of the tumor revealed: Struma nodosa. Reviewing the literature we found only seven cases described. We present development of the thyroid gland and origins causing ectopy.
