(One Year Interval) Staged Surgery of Giant Lumbar Dumbbell Neurofibroma

ABSTRACT

Giant dumbbell neurofibroma is a rare tumor which belongs to large family that is the nerve sheath tumor composed of two main types of tumors that include neurofibroma and schwannoma. Neurofibroma arises from a mesenchymal origin closer to a fibroblast which differs from the schwannoma arising from the progenitor of the schwann cell. I report on one case of giant lumbar dumbbell neurofibroma that occured in the spinal and paraspinal retoperitoneal region which was removed by combined and one-year delayed surgery.
