[Management of plexiform neurofibroma isolated in childhood: four patients].

Plexiform neurofibroma is a rare and benign tumor often associated with type 1 neurofibromatosis (NF1) or Von Recklinghausen's disease. Present in one third of cases of NF1, there are isolated forms where the diagnosis should remain a diagnosis of exclusion. We report four cases of isolated plexiform neurofibromas found in children from topographies and we discuss the pretherapeutic assessment, the surgical management and the long-term follow-up.
