Abstract
Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare multi-system disease that presents significant diagnostic challenges due to its complexity and low incidence (White and Dubey, 2023). It affects males and females equally, though males may exhibit more active disease at diagnosis and often require more aggressive treatment (Liu et al., 2023). The hallmark features of EGPA include delayed-onset asthma, eosinophilia in tissues and blood, and vasculitis affecting small to medium-sized arteries (White and Dubey, 2023). EGPA falls under the category of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), whereas only about half of EGPA patients test positive for ANCA (Khoury et al., 2023).
