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.
