Radiation-induced neurofibromata

Two cases are reported of neurofibromata occurring as a late complication of radiotherapy which was given during childhood. In neither case was there any stigmata of neurofibromatosis. In both cases the neurofibromata arose in the cervical region and only in the field of irradiation. One occurred 13 and the other 11 years after the putative course of irradiation.
