title: [Neurofibromatosis type 2 in childhood: a clinical characterization].
abstract: BACKGROUND
  Neurofibromatosis type 2 (NF2) is a dominantly inherited neuroectodermal syndrome that predispose to the development of tumors of the central and peripheral nervous system. Additional features include eye and skin abnormalities.
  
  
  METHODS
  A 12-year old male with diagnosis of MF2 according to Baser et al and presentation in childhood was included. A comprehensive bibliographic review of evolution of the diagnostic criteria for NF2 in children was performed.
  
  
  CONCLUSIONS
  The pattern of presentation of NF2 in childhood differs from adulthood in many aspects. Ophthalmologic and skin manifestations, and not an auditory dysfunction, are the most common initial symptoms in prepuberal-onset NF2. The most frequent symptoms and signs at presentation are posterior subcapsular cataract, skin manifestations as NF2 plaques and/or peripheral nerve tumors, and neurological dysfunction related to isolated or multiple cranial nerve deficits (other than nerve VIII), brainstem masses or spinal masses. As sensitivity of diagnostic criteria in children is low, those prepuberal patients with congenital or early-onset cataracts and typical skin manifestations of NF2 should be systematically assessed.
