This study looks at skin samples from 50 people with different types of vasculitis, a condition where blood vessels become inflamed. Researchers want to understand how the disease affects the skin at a molecular level. Participants must have an active skin rash related to their vasculitis. No new treatments are being tested; the goal is to gather information to improve future diagnosis and care.
