A case of neurofibromatosis with varied clinical symptoms due to parental consanguinity is reported. The patient presented the following manifestations: mental retardation, curved tibias, kyphoscoliosis, basillary impression with pyramidal syndrome and parkinsonism, subluxation of the lenses, bilateral blindness and hypogonadism. Subluxation of the lenses and hypogonadism are rarely present in this disease. The hypogonadism was of the hypogonadotrophic type without evidence of pituitary or gonadal tumor. The possible causes of endocrine dysfunction in neurofibromatosis are discussed. The more likely hypothesis explains endocrine dysfunction on the basis of an elongation of the pituitary stem; if such abnormality was caused by gliosis of the optic chiasma, an explanation would be apparent for the bilateral blindness presented by this patient since infancy. The alterations of the nervous, endocrine and osteoarticular systems and the ocular manifestations that can be present in von Recklinghausen's disease are reviewed.
