Eosinophilic granulomatosis with polyangiitis (EGPA; formerly known as Churg-Strauss syndrome) is classified as an antineutrophil cytoplasmic antibody (ANCA)-associated small vessel vasculitis. It is a multisystem disorder and can affect every organ system. EGPA is a rare disease, with an estimated prevalence of 1/70,000-100,000 in Europe. As its onset usually occurs in adulthood, data from pediatric patients are limited. We present here a very rare practical EGPA clinical case involving a pediatric patient. Presently, data on mepolizumab usage in pediatric patients are limited, with only a few case reports published.
Keywords: mepolizumab in pediatrics; pediatric EGPA; small vessel vasculitis.
