The identification of submandibular ectopic normal thyroid in the lateral neck with a coexisting normally located and functional thyroid gland is rare. Ectopic normal thyroid tissue in the midline location is most commonly related to aberrant migration along the thyroglossal duct (ie, lingual thyroid). A 54-year-old man with a 6-month history of visible asymptomatic swelling in the right submandibular region had ultrasonography and Tc-99m pertechnetate imaging.

Abstract
The identification of submandibular ectopic normal thyroid in the lateral neck with a coexisting normally located and functional thyroid gland is rare. Ectopic normal thyroid tissue in the midline location is most commonly related to aberrant migration along the thyroglossal duct (ie, lingual thyroid). A 54-year-old man with a 6-month history of visible asymptomatic swelling in the right submandibular region had ultrasonography and Tc-99m pertechnetate imaging.
