• Histopathologically, the disease is a panarteritis with inflammatory mononuclear cell infiltrates within the vessel wall with frequent giant cell formation.
• Leukocytoclastic Vasculitis (also known as Microscopic Polyarteritis): it is a necrotizing vasculitis affecting arterioles/capillaries/venules in which all lesions are of the same age. Granulomatous inflammation is absent
