Mimics of vascular ischaemia: Rare variant of drug-induced vasculitis and associated autoimmune pathogenicity – A report of two cases

Drug-induced vasculitis is the inflammation of blood vessels instigated by a pharmaceutical agent and can mimic vascular ischaemia. The inflammatory environment can be acute or chronic. Activation of endothelial cells and coagulation factors predisposes a vessel to thrombosis and ischaemia of the tissues and organs it supplies. An element of autoimmune activation may contribute to the pathogenesis and subsequent clinical manifestation of this...
