A fifteen year old boy with characteristic findings of von Recklinghausen's disease admitted to our clinic due to malunited fracture of the right forearm.
In July, 1970, osteosynthesis was performed, but two months after surgery, he fell down and refracture occurred.
Roentgenogram revealed irregularity of the shaft of the bones, narrowing of bone diameter, and erosive defects which were characteristic to von Recklinghausen's disease.
Neurofibroma was not demonstrated histologically from the neighbouring tissue, but fibrous tissue was found to be filled.
