Characterization of Hypereosinophilia in University Health Care Systems

Hypereosinophilia (HE), defined as peripheral blood eosinophilia ≥1500 cells/μL, is an uncommon finding in clinical practice that may be discovered incidentally or with associated symptoms. HE warrants further investigation as it can portend life-threatening diseases such as malignancy or the eosinophil-associated end-organ damage of hypereosinophilic syndrome s (HES).1 The differential for HE is broad and includes malignancies and secondary causes such as adverse medication reactions, parasitic infections, and eosinophilic granulomatosis with polyangiitis (EGPA).
