Immune checkpoint inhibitor-related acral vasculitis

Abstract

Commentary on « Ipilimumab induced vasculitis » by Padda A. et al., J Immunother Cancer. 2018;6:12. The authors diagnosed a small vessel vasculitis following treatment with anti-CTLA-4 (ipilimumab) for a resected stage III B/C melanoma. We report a similar case of acral vasculitis occurring with a combination of anti-CTLA-4 (tremelimumab) and anti-PD-L1 (durvalumab) prescribed for the management of a metastatic urothelial bladder cancer. In contrast to Padda A. et al., we observed a significant improvement with oral corticosteroids.
