title: Submandibular ectopic thyroid with normally located thyroid gland.
abstract: Ectopic thyroid is a rare developmental anomaly of the thyroid gland which is defined as the presence of thyroid tissue at a site other than the pretracheal area. Nearly 1 to 3% of all ectopic thyroids are located in the lateral neck. Simultaneous submandibular ectopic thyroid tissue presenting with a functional orthotopic thyroid gland is extremely rare. In this article, we report a 37-year-old female case admitted to our clinic with a complaint of swollen neck in whom ultrasonography revealed submandibular ectopic thyroid tissue presenting with an orthotopic thyroid gland.
