A, Before fluticasone therapy (but after treatment with lansoprazole and empiric dietary restriction), endoscopy grossly revealed findings consistent with eosinophilic esophagitis (EoE), including furrows (example marked with a thinner arrow), scattered white plaques (example marked with a thicker arrow), and a decreased vascular pattern. B, After 4 months of swallowed fluticasone therapy, repeat endoscopy demonstrated full resolution of plaques and furrows, along with return toward a normal vascular pattern (example marked with an arrow).
