M05.2: Rheumatoid vasculitis

Rheumatoid vasculitis is a serious complication associated with longstanding, severe rheumatoid arthritis, an autoimmune disorder where the body's immune system mistakenly attacks its own tissues. In rheumatoid vasculitis, this same immune system malfunction causes inflammation in the blood vessels (vasculitis). It primarily targets small and medium-sized blood vessels, usually those in the skin, nerves, and the lining of the joints. Common symptoms can include skin changes such as ulcers or rashes, nerve problems such as numbness or weakness, and joint pain. The exact cause is unknown, but it is thought to be a response to inflammation that has spread to the blood vessels. Being a progressive condition, it can worsen over time or fluctuate with periods of relief and flare-ups. It is not contagious and cannot be passed from one person to another.
