ABSTRACT This review systematically examines the association between vasculitis and malignancies by summarizing the risk of tumor‐associated vasculitis, their clinical characteristics, and proposed pathogenic mechanisms across different vasculitic subtypes. Relevant case reports and mechanistic studies are integrated to provide a comprehensive overview of this entity. The findings offer practical value for rheumatologists in distinguishing primary vasculitis from malignancy‐associated forms and optimizing patient surveillance, and for oncologists in improving recognition of tumor‐associated vasculitis to reduce the risk of misdiagnosis, supporting more accurate clinical decision‐making and risk management.
