title: [Sporadic recurrent hypertrophic polyneuropathy. Clinical-histological contributions on differential diagnosis].
abstract: The authors report about an own case of recurrent sporadic hypertrophic polyneuropathy and describe the clinical course and histologic picture with reference to the literature. The disease is characterized by recurrences of subacutely occurring polyradiculoneuropathy and sequent nearly complete remission. Clinical examination discloses preferentially symmetrically and distally occurring motor paresis while sensibility in most cases is less affected. The peripheral nerves may be enlarged after a few relapses and frequently painful to pressure during the bout. Excessive increase in CSF proteins is found only during the bout. Motor nerve conduction velocity is considerably reduced. Histological pictures typically present an onion bulb formation of the Schwann cells with marked proliferation of connective tissue. There frequently younger individuals are involved; the relation female to male is 3:1. Differentiation has to be made concerning hereditary and symptomatic forms of hypertrophic polyneuropathy. Etiological factors of the disease are discussed.
