Systemic Vasculitis: Associated Conditions

Vasculitis is often related to other diseases, sometimes occurring in patients that are also affected by these conditions.

• Autoimmune system diseases. These are diseases that the vasculitis patient may have had for years, in which the body's immune system mistakenly attacks the body itself. Examples include systemic lupus erythematosus (lupus), rheumatoid arthritis, and scleroderma.
• Blood cancers. These include leukemia and lymphoma.
