Upper endoscopy showed confluent whitish exudates and longitudinal red furrows in the proximal and the distal esophagus (fig. 1a). Biopsies from these lesions revealed a predominantly eosinophilic inflammation with a peak infiltration of 164 eosinophils per high power field (fig. 1b), which confirmed the diagnosis of EoE.
