[Three kinds of chemodectoma in one patient--a rare case].

Tumors arising from paraganglioma tissue are properly called paragangliomas. Preferentially these tumors are named for their site of origin. In the head and neck they are most commonly found arising from the carotid body (glomus caroticum), the jugular bulb (glomus jugulare), the tympanic cavity (glomus tympanicum) and the vagal ganglia (glomus vagale). Mutiple paragangliomas may occur in 2-10%. The purpose of this study was to present the rare case of patient with three kinds of chemodectoma: glomus tympanicum, jugulare i vagale.
