SINCE Barber's1 and Ducroquet'slb publications in 1939, bowing of the legs, fractures and pseudarthrosis have been accepted as one of the manifestations of von Recklinghausen's neurofibromatosis. Clinically and roentgenologically the lesions are clearly described, but the morphologic changes taking place in the skeletal system are as yet not completely understood. The first, and apparently only, microscopic examination of tissue in pseudarthrosis connected with neurofibromatosis was published by Green2 in 1943.
