[Familial malignant carotid body chemodectoma with lymph node metastases. Light and electron microscopy study (author's transl)].

A case of malignant carotid body chemodectoma with neighbouring lymph nodes metastases is reported. The case is noteworthy as it was accompanied by another jugulotympanic chemodectoma. There was also hereditary component as four of the patients forebears had been operated for cervical chemodectomas. An ultrastructural study showed the characteristic secretory granules. 32 other cases of tumors of carotid body and jugular glomus with metastases are reviewed.

[Acoustic neuroma. Apropos of a series of 40 cases].

The authors present statistics of 40 acoustic neuromas operated upon by micro-surgical technique in co-operation with oto-neuro-surgery. As regards clinical picture, all persons presenting with unilateral progressive sensoryneural deafness should be subjected to cochlear vestibular and radiologic examination. They advocated essentially two routes:--translabyrinthine approach for the tumours within the internal auditory meatus, --posterior fossa approach for the other tumours. They reported their results and analysed the major advantages of the microsurgical technique which diminish considerably the risk of this surgery, so that the functional result should be of first importance.
