Other symp-toms: (i) pigmentation of the skin in brownishpatches usually situated on the trunk and upperportions of the limbs; (2) mental manifestations,such as depression and diminution of prognosis is uncertain (Fig. 117). Neuroma following amputation consists of abulbous mass developing on the proximal endsurface of a divided nerve. It is due to a rapid growth of the sectional axis-cylinders and proliferation of the surround-ing connective tissue. It is usually very painful to pressure and thus itprevents from using an artificial limb. Twitching of the muscles is alsoobserved and such a neuroma may be the point of departure for epilepticseizures. Removal of such tumors is a necessity but recurrences Fig 125.—Neurofi-bromatosis (v. Reckling-hausens disease.) MULTIPLE NEURITIS 385 MULTIPLE NEURITIS Pathology.—The lesion described in the preceding chapter is thesame when several nerves are simultaneously affected. The specialfeature of polyneuritis lies in the fact that the atrophic state of the nervesis more marked than the inflammatory, and that perineuritic and inter-stitial changes are extremely slight, while the nerve-fibers are markedlyaltered. Another peculiarity is found in changes in the central nervoussystem. Thus poliomyelitic foci in the cells of the anterior cornua, de-generative condition of the posterior columns (see my case in , 1905), inflammation of the bulbar nuclei, have been observed
