Childhood polyarteritis nodosa

Childhood polyarteritis nodosa is a rare, systemic vasculitis affecting medium-sized arteries, leading to inflammation and damage, primarily in children. It is clinically significant due to its potential to cause severe complications, including organ ischemia and long-term sequelae if not diagnosed and treated promptly. A key association is its link to viral infections, particularly hepatitis B, which can trigger the disease in susceptible individuals.
