Cutaneo us vasculitis (CV) has a broad spectrum of etiologies, and drugs are one of the main culprits. With the increasing use of targeted therapies in medicine, especially in rheumatology and oncology, the number of CV cases reported due to these drugs has increased. Therefore, the recognition and treatment of CV associated with targeted agents have become more and more important. In the literature, anti-TNFs (n = 73, 59.5%), secukinumab (n = 7, 6%), rituximab (n = 5, 4%), tocilizumab (n = 1, 0.8%), ustekinumab (n = 8, 6.5%), abatacept (n = 3, 2.4%), Janus kinase inhibitors (n = 3, 2.4%), alemtuzumab (n = 3, 2.4%), and immune checkpoint inhibitors (n = 20, 16%) have been reported as responsible agents. However, our knowledge of the pathogenetic mechanisms is fairly limited, and the standardized management is yet to be established. Furthermore, though it is uncommon, this complication may pose a safety issue. In this manuscript, we reviewed the literature on CV with or without systemic involvement related to targeted agents. We also proposed the pathogenetic mechanisms of these adverse events. Thus, we aimed to make it easier for clinicians to manage similar cases by reviewing the diagnosis and treatment processes.
