A rare case of double ectopic thyroid without orthotopic thyroid gland

Double Ectopic Thyroid Gland in a 10-Year-Old Filipino Boy

“…Ectopic thyroid results from an aberrancy in the normal migration pathway of the thyroid gland due to an arrest in the descent and/or an interruption in the pathway causing maturation and development in other locations other than the true final anatomic position. 1 Although a lingual thyroid is the most frequent location of ectopic thyroid tissue, other locations such as the sublingual region, tracheal, submandibular, lateral neck, palatine tonsils, and axilla also exist, 2 and ectopic thyroid tissue in distant sites such as the ovary and GI tract have also been reported. 2 Intratracheal thyroid tissue represents only 7% of all intraluminal tracheal masses.…”
