[Neurofibromatosis].

As the neurofibromatosis belong to the so-called rare diseases, all patients with a suspicion or diagnosis of NF should get the opportunity to present to an interdisciplinary NF Center, mostly situated at University Hospitals, where competent counseling on the individual disease phenotype may be provided. Here the patients will be informed on the necessary diagnostic steps, their frequency as well as on practical steps in case of acute deterioration. Most NF centers are run by neurosurgeons or neurologists or pediatricians, working in a network with geneticists, neuro-radiologists, ophthalmologists, dermatologists, plastic and general surgeons, psychologists, psychiatrists and social work experts. They participate regularly in neuro-oncological tumor and sarcoma tumor boards, skull base tumor centers, comprehensive hearing centers, and deliver all the treatment opportunities provided by certified brain tumor centers, among those the inclusion in special diagnostic and treatment studies or the contact information to patient support groups.
