title: [Paraganglioma of the jugulo-tympanic glomus. Anatomo-pathological aspects].
abstract: 15 extensive glomus jugulare tumors have been studied. Optic and ultrastructural data were very similar to those which have been reported in the literature. They possessed a local aggressiveness, demonstrated by progressive spreading in soft tissues and bone, intravascular digitations and destruction of cranial or sympathetic nerves. Dura-mater was usually preserved and prevented extension close to the brain stem. In this group, no functional activity of catecholamine-secreting tumor nor metastasis proving a malignant form were observed.
