ABSTRACT

Eosinophilic gastroenteritis is a rare disorder, characterized by increased eosinophil count and eosinophilic infiltration in gastrointestinal organ. Its etiology is unknown, but affected by parasitic infestation, collagen disorder, malignancy and allergic disorder. There have been several reports all over the world that Eustoma rotundum, Schistosomiasis, Ancylomastoma and Ascaris are the sources of parasites occurring eosinophilic gastroenteritis. But the reports on Metagonimus yokogawai have not presented yet. We experienced a case of metagonimiasis with a presentation of small bowel perforation by eosinophilic enteritis. A 35-year-old woman was admitted to the hospital because of epigastric pain. Six months ago, she had been treated as metagonimiasis. This time she took antiparasitic agent again, but abdominal pain was aggravated and perforation of small bowel was detected. The pathologic finding of resected small bowel showed perforation and obstruction with diffuse and dense eosinophilic infiltration.
