title: [Peripheral polyneuropathy due to sarcoidosis in a patient with intrathoracic, ocular and skin lesions].
abstract: Sarcoidosis is a multisystem disorder of unknown etiology presenting most frequently with bilateral hilar lymphadenopathy (BHL), pulmonary infiltration, and ocular and skin lesions. Neurological manifestations are found in about 5% of patients with systemic sarcoidosis. We report the case of a 58-year-old woman with neurosarcoidosis manifesting as isolated, peripheral polyneuropathy. This is a rare neurological manifestation. Two years before admission, she was found to have an abnormal chest radiograph showing BHL, and pulmonary sarcoidosis was diagnosed by lung biopsy. Six months later, she noted facial erythematous lesions, and lupus pernio was confirmed by skin biopsy. Fifteen months before admission, she developed visual disturbance of the right eye caused by sarcoid-uveitis. Two months before admission, she complained of paresthesia and weakness of limbs. She was admitted for nerve-biopsy. Sural nerve biopsy revealed sarcoid granulomas in the epineurial space, periangitis and axonal degeneration. Neurologically, the diagnosis of mononeuritis multiplex without cranial nerve palsy was made. Treatment with 30 mg prednisolone daily was initiated, and neurological and extraneurological improvement was noticeable within two weeks of treatment. The dose was carefully lowered over several months.
