The majority of mild neurological symptoms are frequently ignored by the patients themselves or even physicians. However, considerable cases in this situation make people annoying and feel the low quality of life. Moreover, these neurological symp-toms often get solved by correct diagnosis and medical attention. Sarcoidosis is a chronic systemic disorder of unknown etiology that can affect any organ through the accumulation of non-caseating epithelioid granuloma. Neurologic manifestation of sarcoi-dosis is rare and estimated to be about 5-10%. Due to this rarity, some neurological symptoms of sarcoidosis are in the lack of medical suspicion easily. In this report, we describe a 45-year-old female diagnosed as sarcoidosis with severe small fiber neuropathy (SFN) accompanied by autonomic involvement. She had been a sufferer from mild persistent neurological symptoms and has improved with treatment after the correct diagnosis.
