Abstract

Polyarteritis nodosa is one of the necrotizing vasculitis inv'olving small and medium sized arteries. Polyarteritis nodosa may affect many organs such as kidney, musculoskeletal system, gastrointestinal tract, skin, heart, and nerve. In Cupps and Fauci's autopsy studies, muscle involvement was found in 39% of the patients with polyarteritis nodosa. Commonly Polyarteritis nodosa may be presented clinically by myalgia. We experienced a case of polyarteritis nodosa presenting as myositis, diagnosed by muscle biopsy and renal angiography, which appear with unusual presentation of joint contracture in lt elbow and muscle crarnping pain rather than cornmonly presented myalgla.
