Resolution of Pembrolizumab-Associated Steroid-Refractory Lichenoid Dermatitis with Cyclosporine

[摘要] Checkpoint inhibitors such as pembrolizumab, an anti-PD-1 monoclonal antibody, are a promising new category of oncological therapeutics, associated with a higher risk of immune-related adverse events including dermatological, autoimmune and endocrine sequelae. Here, we present a case of a woman 76 years of age with stage IV lung adenocarcinoma who developed a severe and steroid-refractory lichenoid dermatitis associated with pruritus on pembrolizumab. This eruption resolved completely with a short course of oral cyclosporine. Cyclosporine is a promising and effective treatment option for checkpoint inhibitor-related severe cutaneous eruptions.
