[Polyarteritis]

Abstract

Polyarteritis is an uncommon childhood disease. The different forms of polyarteritis are described. Polyarteritis nodosa is a rare multisystemic disease characterized by high fever, calf pain and subcutaneous nodules. Infantile polyarteritis nodosa shows a peculiar predilection for the coronary arteries and has the worst prognosis. Polyarteritis cutaneous is the localized and mild form of polyarteritis. Hypersensitivity angiitis is described as a leukocytoclastic vasculitis identified by palpable purpura.
