NEUROFIBROMATOSIS originally described by von Recklinghausen in 1882 is often depicted as a chronic progressive hereditary disease characterized by pigmentation of the skin, cutaneous lesions, and numerous tumors developing in association with elements of both the central and peripheral nervous systems. This entity is often complicated by abnormalities of the bones and various malformations. The central nervous system is involved with tumors of the cranial nerves and the brain proper. Mental deficiency is common. Endocrine abnormalities in the form of somatic retardation, under development, and pheochromocytomas have also been encountered. The frequency of von Recklinghausen's disease as studied in the state of Michigan was found to be one case in each 2,500 to 3,300 births.
