Tumors of the Nose and Nasopharynx
The nonchromaffin paragangliomas of the nasal cavity and nasopharynx are an ill-defined group of neoplasms, principally because the existence of a normal glomic organ has not been demonstrated in this area. House et al. (1972) believed their 2 tumors to arise from paraganglia associated with the ganglion nodosum, and Smith et al. (1973) thought the point of origin in their case to be an orbital body with extension through the ethmoid into the nasopharynx. Holmes (1976) believed his case to be metastatic, but it is probably multicentric. In some cases the nasopharyngeal lesion represents a direct extension of a glomus jugulare tumor through the Eustachian tube, or by erosion of the petrous bone (Khanolkar, 1947; Weille and Lane, 1951; Riemenschneider et al., 1953; Williams et al., 1955; Ash and Raum, 1956; Zacks, 1958; Dill, 1959; Rucker, 1963; Black, 1964; Fuller et al., 1967; Oberman et al., 1968; Diepeveen et al., 1969; Silverstone, 1973; Spector et al., 1973), or metastasis to the nose (Rosenwasser, 1958).
