Two cases of sarcoid polyneuropathy were diagnosed by histological examination of the nerve biopsy. The electrophysiological findings in both patients suggested a neuropathy of axonal type, confirmed by a morphological study of a sural nerve biopsy by light microscopy and on teased-fiber preparations. The sarcoid granulomas were multiple, especially in case 2; they were sparse in the epineurial and perineurial spaces and absent in the endoneurium, whose interstitial component contained cellular infiltrations of scattered macrophages. Blood vessel changes were a constant morphological feature. The mechanisms that possibly contribute to the pathogenesis of the sarcoid neuropathy are discussed in relation to previous reports.

Abstract
Two cases of sarcoid polyneuropathy were diagnosed by histological examination of the nerve biopsy. The electrophysiological findings in both patients suggested a neuropathy of axonal type, confirmed by a morphological study of a sural nerve biopsy by light microscopy and on teased-fiber preparations. The sarcoid granulomas were multiple, especially in case 2; they were sparse in the epineurial and perineurial spaces and absent in the endoneurium, whose interstitial component contained cellular infiltrations of scattered macrophages. Blood vessel changes were a constant morphological feature. The mechanisms that possibly contribute to the pathogenesis of the sarcoid neuropathy are discussed in relation to previous reports.Pubblicazioni consigliate
