Overview
Eosinophilic granulomatosis with polyangiitis previously called Churg-Strauss syndrome is a small and medium-sized necrotizing vasculitis, with extravascular granuloma formation. The disease was first described by Churg and Strauss in 1951. The etiology is not known. However, various environmental factors, allergens, genetics, and drugs may play a role in triggering disease process by activating eosinophils, B and T lymphocytes and macrophages. The disease is characterized by the presence of asthma, peripheral eosinophilia, rhinosinusitis, peripheral neuropathy and multiple organ involvements including skin, GI tract, and kidney.
