Polyarteritis nodosa is a rare autoimmune disease (immune system attacking its own body) featuring spontaneous inflammation of the arteries (arteritis). Because arteries are involved, the disease can affect any organ of the body. The most common areas of involvement include the muscles, joints, intestines (bowels), nerves, kidneys, and skin.
