Introduction. Histopathological findings of various inclusions were reported in the central nervous system of amyotrophic lateral sclerosis (ALS) patients, but not in the peripheral nerves. Case report. Our patient was a 66-year-old man with lower limb weakness later involvement of upper limbs, and loss of sphincter control. Neurological examination showed affection of both upper and lower motor neurons. He had paresthesia of the left side of his body and socks-distribution numbness. Histopathology of the sural nerve and genetic report showed basophilic periodic acid-Schiff (PAS)-positive intra-axonal inclusions and heterozygous L144F mutation in the exon 5 of the SOD1 gene. Conclusion. It seems that presence of the basophilic peripheral nerve inclusions may suggest diagnosis of SOD1 positive ALS.
