Abstract
Here are reported three cases of pancreatitis with eosinophilia. To date, there have been only a few papers concerning pancreatitis accompanied by eosinophilia, and a reasonable explanation for its existence has not yet been established. Among the cases in this study, some gastrointestinal distress, especially diarrhea, was noted. It seemed that eosinophilic gastroenteritis might have some relation to pancreatitis accompanied by eosinophilia. Although, the detailed mechanism is still unknown, some possible causalities are discussed.
