 In patients with eosinophilic esophagitis, basal cell hyperplasia and impaired differentiation of the esophageal epithelium were shown to be associated with disease activity, independent of the eosinophil count. In the present study, we evaluated the clinicopathologic characteristics of 33 patients who underwent endoscopic and histologic evaluation before and after treatment to determine the utility of beige mucosa observed with narrow band imaging(NBI)or blue laser imaging(BLI)in assessing treatment efficacy. The increase in CK14 immunoreactivity was observed in the epithelium of all patients with beige mucosa. The beige mucosa as an endoscopic finding was associated with impaired differentiation of the esophageal epithelium, suggesting its utility as a marker for the diagnosis of eosinophilic esophagitis and the evaluation of treatment efficacy.
