Sarcoidosis is multisystemic granulomatous disease of unknown etiology ogenesis, and most frequently presented with bilateral hilar lymphadenopathy, pulmonary infiltration, skin and eye lesion. However, neurological involvement including peripheral neruopathy is relatively rare. We report a patient who had sensorimotor polyneuropathy without other systemic or organ involvements frequently reported in sarcoidosis. Laboratory investigation suggestive of sarcoidosis lead to sural nerve biopsy for confirmation, which demonstrated noncaseating granulomatous changes. Sarcoidosis should be included in the differential diagnosis in subacute polyneuropathy even if there is no usual symptoms or signs suggestive of the systemic disease.
