title: Influenza vaccination induced leukocytoclastic vasculitis and pauci-immune crescentic glomerulonephritis.
abstract: Influenza vaccination is a widely accepted practice, particularly among the elderly and high-risk individuals. Minor and transitory side effects following the vaccination are common, while systemic complications are infrequently reported. We describe here a case of a patient who presented to the emergency room with arthralgia, myalgias and purpura, following influenza vaccination. Necrotizing vasculitis associated with pauci-immune glomerulonephritis was observed on kidney biopsy. With increasing use of influenza vaccination, attention should be drawn to the possible expression of systemic adverse effects such as vasculitis and glomerulonephritis.
