| neurofibroma, plexiform | A type of neurofibroma representing an anomaly rather than a true neoplasm, in which the proliferation of schwann cells occurs from the inner aspect of the nerve sheath, thereby resulting in an irregularly thickened, distorted, tortuous structure. In some instances the process extends along the course of the nerve and may eventually involve the spinal roots and the spinal cord. (12 Dec 1998) |
