Ectopic thyroid refers to the presence of thyroid tissue located far from its usual anatomic place with no vascular connection to the main gland. Ectopic thyroid tumor is a thyroid neoplasm that occurs in sites other than the cervical thyroid gland. Ectopic thyroid tumors arising in the mediastinum without connection to the cervical thyroid gland are very rare. They are either discovered incidentally or present with symptoms referable to a mediastinal mass. We present a case of a mediastinal ectopic thyroid in a 70-year-old man investigated for chest pain and cough. Radiology showed a well-defined lesion in the mediastinum. Biopsy and resection specimens showed follicular adenoma of the thyroid. On immunohistochemistry, tumor was reactive for thyroglobulin. The possibility of ectopic thyroid in the mediastinum which can be a site for adenoma or carcinoma of the thyroid should be considered in the differentials of a mass lesion in the mediastinum. Symptomatic diseases should be treated surgically.
