Nasal congestion discharges purulent or bloody secretions

Churgstrauss syndrome (Churgstrauss syndrome, CSS), also known as allergic granulomatous vasculitis or allergic granulomatous vasculitis, is a systemic necrotizing vasculitis mainly involving the middle, small arteries and veins. Massive eosinophil infiltration and extravascular granuloma formation and necrotizing vasculitis. Earlier, Churg and Strauss first reported 13 cases with asthma, elevated eosinophils, granulomatitis, necrotizing systemic vasculitis, and necrotizing glomerulonephritis in 1951. The Chapel Hill conference in 1993 defined Churg-Strauss syndrome as necrotic vessels with asthma and eosinophilia affecting the respiratory tract, with large amounts of eosinophil infiltration and extravascular granuloma formation affecting medium-sized vessels inflammation. Allergic rhinitis is often the initial symptom of CSS, accompanied by recurrent sinusitis and nasal polyps. The main symptom is congestion of the nose and discharge of purulent or bloody secretions.
