More than 99% of thyroid cancers arise eutopically within the thyroid gland. The most frequent sites of ectopic thyroid tissue are lingual, sublingual, thyroglossal, laryngotracheal, and lateral cervical. Thyroid tissue can also be found in remote structures that were associated with the thyroid anlage during development, including the esophagus, mediastinum, heart, aorta, adrenal, pancreas, gallbladder, and skin. Ectopic thyroid tissue can be subject to the same pathological processes as normal eutopic thyroid tissue such as inflammation, hyperplasia, and tumorigenesis. The aim of this review is to describe aspects of thyroid cancer arising from the ectopic thyroid tissue in the neck in regard to epidemiology, diagnosis, and treatment and to present an illustrative series of cases of ectopic thyroid cancer.
