Clinical presentation vs endoscopy for an early diagnosis of eosinophilic esophagitis: a case report.

Eosinophilic esophagitis (EoE) is a type-2 mediated, chronic inflammatory disease showing an increase of both incidence and prevalence. Early diagnosis is mandatory, to prevent fibrostenotic complication of the disease. Due to the low sensitivity of the classic endoscopic features of the disease, a strong clinical suspicion should drive the decision to collect mucosal biopsies of the esophagus. We describe the case of an atopic patient suffering from dysphagia with normal esophageal mucosa and frank histological hallmarks of the disease.
