title: [Tumor-like transformation of the median nerve in neural muscular atrophy].
abstract: This paper reports a case of local enlargement of the median nerve in the upper arm due to the very rare condition of hypertrophic neuropathy. A characteristic feature of this affection of peripheral nerves, the cause of which is unknown, is the onion-skin-like hypertrophy of the Schwann cells and chronic neurogenic muscular atrophy. The examination of the nerve distension is described. The appropriate treatment is not known; however, the prognosis is favourable in cases showing very slow progression.
