  • Ectopic thyroid is an uncommon embryologic aberration characterized by the presence of thyroid tissue in a site other than its usual pre-tracheal location. Dual ectopic thyroid is extremely rare, only few cases have been reported in the literature. Physical examination, laboratory test and radiologic examinations are usually performed for the diagnosis and therapeutic plan of dual ectopic thyroid. We report a 36-year old female with dual ectopic thyroid in lingual and hyoid regions but without thyroid tissue in its normal area. The diagnosis was made through pathologic examination after surgical resection.
