Abstract: Objective To analyze the clinical characteristics and mechanisms of pustular psoriasis caused by duvalumab injection so as to provide a reference for rational use of duvalumab injection. Methods One case of pustular psoriasis (PP) that was considered to have been caused by duvalumab was analyzed. Related literature was reviewed while the process of diagnosis and treatment, possible mechanisms, clinical manifestations and treatment regimens were summarized. Results Correlation analysis suggested that the immune-related adverse reactions of the skin in this patient were likely induced by durvalumab injection. After effective treatment with guselkumab and discontinuation of durvalumab injection, the patient’s symptoms of PP were relieved. Conclusion Durvalumab may induce PP via activation of the IL-36/IL-17 inflammatory axis. Clinicians should be alert to such immune-related adverse events (irAEs) to ensure early detection and quick interventions.
