Images corresponding to the same patient before and after therapy with topical fluticasone propionate to illustrate changes in the esophageal epithelium. A: Marked epithelial proliferation with basal-cell hyperplasia reaching up to superficial strata, in addition to elongated connective papillas, which appear thicker and hypervascularized. Numerous eosinophils infiltrate into the epithelium. B: Obtained after 3 months under treatment with fluticasone propionate. The esophageal epithelium exhibits fewer cells and recovered stratification, with basal cells occupying not more than 15% of esophageal thickness, and no eosinophilic infiltration (hematoxylin and eosin, x200).
