Abstract
- Eosinophilic pancreatitis is a rare disorder that frequently accompanies peripheral eosinophilia and/or eosinophilic gastroenteritis. Eosinophilic pancreatitis can mimic a pancreatic neoplasm by forming a pancreatic mass with focal pancreatic eosinophilic infiltration. Because eosinophilic pancreatitis responds well to steroid treatment, it is important to distinguish eosinophilic pancreatitis from pancreatic neoplasm. Thus, fine needle aspiration biopsy (FNAB) should be considered in patients with a pancreatic mass accompanied by peripheral eosinophilia and/or eosinophilic gastroenteritis. We describe a case of eosinophilic pancreatitis with annular pancreas that was diagnosed by FNAB. This is the first reported case of eosinophilic pancreatitis with annular pancreas diagnosed by FNAB.
