title: Cutaneous necrotizing vasculitis associated with hepatitis A virus infection.
abstract: Hepatitis A virus has been recognized as an etiologic factor of cutaneous necrotizing vasculitis in only 2 adult cases. We describe a 2-year-old Bedouin girl who developed cutaneous necrotizing vasculitis during the acute phase of hepatitis A infection. The cutaneous punch biopsy from an ecchymotic lesion revealed microscopic findings of a necrotizing vasculitis process involving the superficial and deep blood vessel plexuses. Fibrin thrombi were present in the lumen of a few blood vessels. She was treated with 2 mg/kg/day, tapered during 5 weeks. Serum liver enzymes returned to the normal range within 6 weeks of the first presenting symptom. A few skin scars were noted in previously necrotic areas. Hepatitis A is one of many viruses that may be an etiologic factor in development of cutaneous necrotizing vasculitis in children.
