Abstract

Eosinophilic gastroenteritis is a rare disease characterized by tissue eosinophilia that can involve different layers of the gut wall. The pathogenesis and pathophysiology of this condition are poorly understood. Its clinical feature depends on the type of layer and location involved. The endoscopic and radiologic findings of eosinophilic gastroenteritis mimicked many other gastrointestinal diseases We experienced a case of diffuse eosinophilic gastroenteritis in a 21-year-old male who presented severe vomiting and weight loss. After performing gastrofiberoscopy, barium study for upper gastro intestinal tract and abdominal computed tomography, we concluded that the lesion was gastric tumo with severe antral obstruction. Then, we carried out subtotal gastrectomy. We could confirm the diagnosis of eosinophilic gastroenteritis by full-thickness biopsy of the stomach wall. We report this case with a brief review of the literatures.
