Picture of Polyarteritis Nodosa
Polyarteritis nodosa is an autoimmune condition in which inflammation develops in the arteries. Different muscles, joints, kidneys, nerves, intestines, and skin areas may be affected depending on which arteries are inflamed. Immunosuppressive medications including azathioprine and cyclophosphamide may be used to treat polyarteritis nodosa. Prednisone may be prescribed as well.
