Introduction:
EGPA, a rare yet potentially life-threatening systemic necrotizing vasculitis affecting the small vessels systematically. This disease is known to develop over three phases: the prodromal/allergic phase (hallmarked by hard to treat asthma, sinusitis and allergic rhinitis) then followed by the second eosinophilic stage with peripheral or organ infiltrating eosinophilia and last stage being the vasculitic stage. Not all patients develop the three however our patient did demonstrate all three phases with the last one being the most severe manifestation targeting the peripheral nerves.
