[Malignant neurofibroma of the cervical portion of the vagus nerve].

The authors give an account of a malignant neurofibroma of the cervical portion of the vagus in Recklinghausen's disease in a 29 year-old man. The tumour was removed with part of the nerve. Relatively shortly after operation a local relapse of the tumour developed, with propagation into the posterior cranial fossa, which proved fatal.
