title: [A case of multiple chemodectoma: clinical and electron microscopical studies].
abstract: We observed electronmicroscopically and clinically a case of multiple chemodectoma, which has occurred from glomus caroticum sinistra and glomus jugularis sinistra of a 18 year old boy. The diagnosis was especially made by an angiography of the left common carotid artery and by a retrograde venography of the left internal jugular vein. Electronmicroscopically two kinds of tumor cells in this chemodectoma were identified. These cytoplasmas showed cored neurosecretory granules measured 125 to 250 A in diameter markedly increasing in number. Moreover in the island of the tumor cells of the carotid body tumor we happened to observe the nerve ending.
