Abstract

<p>The patient is a 46-year-old woman admitted with epigastric pain and nausea. She was found to have elevated pancreatic enzymes and treated for acute pancreatitis. Imaging findings showed uneven contrast enhancement of the pancreatic body to tail and enlargement of the caudal pancreatic duct. A pancreatic tumor was suspected. Although no definitive histologic diagnosis was obtained using endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA), the possibility of pancreatic body cancer could not be ruled out, and resection was performed. The resected specimen showed characteristic histologic findings, leading to a diagnosis of type 2 autoimmune pancreatitis.</p>
