Abstract

Anti-Hu antibody causes paraneoplastic syndrome of the nervous system. Most of the anti-Hu antibodies are found with small cell lung cancer, but can rarely be found with other cancers such as non-small cell lung cancer, prostate cancer, and breast cancer. We report a 57-year-old male patient with advanced gastric adenocarcinoma who had paresthesia and limb ataxia. Electrophysiologic study and imaging showed peripheral neuropathy accompanied with myelitis. Anti-Hu antibody was detected in the patient’s serum, leading to the diagnosis of paraneoplastic syndrome.
