Polyarteritis nodosa (pan)
-
Polyarteritis nodosa is a systemic necrotizing vasculitis that typically affects medium-sized muscular arteries and occasionally affects small muscular arteries, resulting in secondary tissue ischemia. The kidneys, skin, joints, muscles, peripheral nerves, and gastrointestinal (GI) tract are most commonly affected but any organ can be. However, the lungs are usually spared. Patients typically present with systemic symptoms (eg, fever, fatigue). Diagnosis requires a biopsy or arteriography. Treatment with corticosteroids and immunosuppressants is often effective.
(See also Overview of Vasculitis.)
Polyarteritis nodosa (PAN) is rare (about 2 to 33 cases/million). It affects mainly middle-aged adults, and incidence increases with age, peaking in people in their 50s.
