title: Nonchromaffin paraganglioma (chemodectoma) of thyroid region.
abstract: A case of a paraganglioma located over the thyroid cartilage in the midline is reported. The tumor had all the appearances of a carotid body tumor, but its odd location could not be explained on the basis of previously known areas where paraganglionic tissues have been found. Since a paraganglioma has also hitherto been described within the thyroid gland, clinicians and pathologists alike are cautioned that unusually located paragangliomas may be expected in the future.
