A 47-year old woman was admitted to our hospital for removal of a known mass that was located on the suprasternal notch; specifically, the mass was located on the supero-anterior mediastinuum. The mass was removed by a cervical incision and the histopathologic diagnosis of the resected specimen was hererotopic thyroid tissue with nodular hyperplasia. Mediastinal hererotopic thyroid tissue is a rare malady, so we report here diastinal hererotopic thyroid tissue and we review the relevant medical literature.
