Light and electron microscopic studies of a chemodectoma of the vagus nerve are presented. Forty‐four cases of vagal chemodectoma have been reported to date, but no electronmicroscopic studies have been published. The ultramicroscopic studies showed the presence of clear and dark cells and membrane‐bound neurosecretory granules, and the absence of sustentacular cells and nerve endings. Similar findings have been reported in cases of carotid body and glomus jugulare tumors.
