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.
异位甲状腺是一种罕见的甲状腺发育异常，定义为甲状腺组织出现在气管前区域以外的部位。所有异位甲状腺中近1%至3%位于颈部外侧。同时出现功能性原位甲状腺的下颌下异位甲状腺组织极为罕见。在本文中，我们报告了一例37岁女性病例，该患者因颈部肿胀前来我院就诊，超声检查显示其下颌下存在异位甲状腺组织，同时伴有原位甲状腺。
