Eosinophilic granulomatosis with polyangiitis (EGPA) remains a challenging diagnosis due to its rarity and heterogeneous presentation. The article by Solans-Laqué et al. represents a significant step forward in early detection and management of EGPA [1]. The comprehensive identification of red flags through systematic review and expert consensus underscores the complexity and heterogeneity of EGPA. The creation of a checklist tool is particularly valuable, offering a practical resource for clinicians who may encounter this sneaky and challenging condition.
