[Von Recklinghausen's neurofibromatosis and skeletal changes].

Two cases of von Recklinghausen's neurofibromatosis with osseous involvement are described and compared with cases in the literature. The most important skeletal lesions are dysplastic defects of the skull, macrocranium, deformities of the vertebral column with associated lesions of the vertebral bodies, congenital bowing, pseudarthrosis, length disparity and periostal dysplasias of the extremities, and congenital anomalies, erosions and cysts in the remaining skeleton.
