title: Precocious puberty and neurofibromatosis of von Recklinghausen. A clinical report.
abstract: A case of a 9-year-old boy with neurofibromatosis of von Recklinghausen and precocious puberty is reported. The patient was referred to us because of an unexplained onset of precocious puberty. Clinical manifestations of neurofibromatosis included multiple café-au-lait spots, skeletal anomalies, progressive impairment of vision and precocious sexual development. CT scan and NMR demonstrated the presence of optic gliomas. The correlation between the lesions of retino-hypothalamic projection and production of the neuroendocrinology mechanism of sexual changes is discussed.
