Cutaneous Vasculitis During Secukinumab Treatment.

Secukinumab is an inhibitor of interleukin IL-17A, and is mainly used in the treatment of psoriasis, psoriatic arthritis and ankylosing spondylitis. Although rarely, this drug may induce paradoxical reactions, such as cutaneous vasculitis. Worldwide, only four previous cases of vasculitis induced by secukinumab have been reported. We herein report the first case described in Brazil of cutaneous vasculitis due to secukinumab in a patient with peripheral spondyloarthritis who demonstrated good resolution after withdrawal of the drug and initiation of etanercept. Clinicians should be aware of this rare but potentially serious adverse effect of secukinumab. LEARNING POINTS: Treatment with biologics can cause vasculitis.The vasculitis may be independent of class of the biologic.Only five cases of vasculitis induced by secukinumab have been reported. © EFIM 2020.
