title: Fisher syndrome associated with immune thrombocytopenic purpura.
abstract: We describe a 51-year-old man with Fisher syndrome (FS) and immune thrombocytopenic purpura (ITP) that developed after upper respiratory infection (URI). Laboratory investigations demonstrated immunoglobulin (Ig) G class of anti-GQ1b autoantibody and reduced platelet count with platelet-associated IgG, which spontaneously improved in parallel with neurologic symptoms. Thus the possible association of ITP should be considered when encountering a patient with FS. This patient suggests that there may be a certain infectious agent causing URI, leading to the co-occurrence of FS and ITP.
