Abstract
Background: Polyarteritis nodosa or PAN is a rare disease. It is diagnosed frequently in middle age patients and the elderly. Reduction in hepatitis B virus infection has been associated with a reduction in the prevalence of PAN.
Case Presentation: We present a 78-year-old patient with extensive skin lesions, weight loss, high blood pressure (HBP), polyneuropathy, evidence of hepatitis B virus infection, and a biopsy showing vasculitis of small or medium-sized arteries. Corticosteroid and antiviral treatment were prescribed to the patient and with great results.
Conclusion: PAN is a necrotizing vasculitis that typically affects medium-sized vessels with occasional involvement of small vessels. It is prevalent in older male patients, mostly in patients in their 60s who have recurrent skin ulcers and high blood pressure.
