Background and Clinical Significance: Eosinophilic esophagitis (EoE) is a chronic, immune-mediated inflammatory disorder characterized by esophageal dysfunction and dense eosinophilic infiltration. EoE frequently evolves into a fibrostenotic phenotype, in which uncontrolled inflammation drives progressive tissue remodeling. This evolution increases the risk of complex structural complications—most commonly fixed rings and strictures, and, in rare advanced cases, deep mural injury or fistulization—substantially increasing both diagnostic and therapeutic complexity. Case Presentation: This report describes an uncommon presentation of EoE complicated by a blind-ending esophageal fistula, managed successfully through a multidisciplinary strategy integrating pharmacologic therapy, dietary modification, and endoscopic intervention. Conclusions: Nutritional support through gastrostomy, combined with multidisciplinary medical and endoscopic management, can lead to favorable outcomes in EoE complicated by esophageal fistula. Early recognition and individualized management are essential to optimize outcomes.
