RESUMO
Eosinophilic gastroenteritis is a heterogeneous disorder affecting both children and adults, and is characterized by the presence of an intense eosinophilic infiltrate on histopathology of one or multiple segments from the esophagus to the rectum. Eosinophilic gastroenteritis which may involve more than one layer of the gastrointestinal tract. Clinical features depend on the layer and location to be involved. Involvement of the serosal layer occurs in 10% of cases of eosinophilic gastroenteritis and is typically presented as ascites. The patient in our report was as likely as those who refer with full thickness involvement and presenting ascite, and was completely improved after steroid treatment. The patient was presented a 14-year-old boy that referred to the physician with progressive abdominal pain and ascites. After recognition of eosinophilia in blood and ascite fluid, he was suspected to have Eosinophilic gastroenteritis. Ultimately, following serial examinations and after laparascopic full thickness biopsy Eosinophilic gastroenteritis was closely diagnosed. The patient was treated with prednisolone. The abdominal pain and ascites subsided soon after initiation of steroid treatment
