Relapsing polychondritis (RP) rarely affected the central nervous system (CNS). If the CNS is involved, it can result in psychiatric manifestations. Patients with RP always respond well to glucocorticoids and immunosuppressants. If the therapies fail, biologics can be given, such as tocilizumab, which is a humanized monoclonal antibody against the interleukin-6 receptor (IL-6R). Until now, there have been no randomized clinical trials to test the safety and efficacy of biologics, no reports of RP with psychiatric disorders as initial symptoms, and no reports of tocilizumab used for psychiatric symptoms due to RP. Here, we report a 60-year-old woman with mania, logomania, hallucinations, cognitive disorder, persecutory delusion, and violent tendency as chief complaints. The application of dexamethasone worsened her psychiatric symptoms. After the first infusion of tocilizumab, she achieved complete remission within one week. During the follow-up period, she sustained serological and psychiatric remission. Our case illustrates the safety and efficacy of tocilizumab for psychiatric symptoms of RP.
