Exploring the Vasculitis-Tumors Link: Epidemiological Patterns, Mechanistic Insights, and Clinical Implications

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.
