Macrophage activation syndrome in a child with unclassified systemic vasculitis probably triggered by Parvovirus B19 infection

Macrophage activation syndrome (MAS) is a life threatening complication of chronic rheumatic diseases of childhood and especially of systemic juvenile idiopathic arthritis. Infections, particularly viral, have been suggested to play a triggering role. We describe a case of systemic unclassified ANCA positive vasculitis complicated with fatal MAS triggered probably by Parvovirus B19 infection
