Neurofibroma in the median nerve treated with resection and free nerve transplantation. Case reports.

The commonest tumours of the peripheral nerves are neurolemomas and neurofibromas, both arising from the nerve sheath. Both tumour types are described. It is established that the neurofibroma becomes malignant in about 10% of cases and that removal involves resection of the nerve. Radical resection is nevertheless recommended and the defect in the nerve may be overcome by free nerve transplantation. Two cases are reported.
