title: Eosinophilic Pancreatitis Diagnosed With Endoscopic Ultrasound.
abstract: Eosinophilic pancreatitis (EP) is a rare clinical entity, and few cases have been reported. It usually presents on imaging as a pancreatic mass leading to common bile duct obstruction and jaundice. Since it can mimic a malignancy, eosinophilic pancreatitis is often diagnosed after "false positive" pancreatic resections. To our knowledge, we report the only known case of EP in which the diagnosis was made by fine needle aspiration and core biopsy of the pancreas during EUS, sparing the patient a surgical resection. After a steroid course, there was improvement of clinical symptoms.
