Abstract
Although hemosuccus pancreaticus is a rare complication of chronic pancreatitis, it should be considered in cases of unexplained gastrointestinal bleeding. We report two cases of hemosuccus pancreaticus. Case 1: A 77-year-old man seen for repeated hematemesis was found in computed tomography (CT) to have a splenic artery aneurysm. Hematemesis was considered due to aneurysm rupture into the main pancreatic duct, necessitating surgery. Pathological examination showed the resected specimen to be a true aneurysm without a pseudocyst. Case 2: A 58-year-old man with upper abdominal pain was found in upper gastrointestinal (GI) endoscopy to have bleeding from the papilla of Vater. Abdominal magnetic resonance imaging (MRI) showed a cystic pancreatic tail lesion. We operated based on a diagnosis of hemosuccus pancreaticus due to the pancreatic cyst. Pathological findings of the resected specimen showed mucin-secreting columnar epithelial cells with varying degrees of atypia but without ovarian-type stroma. The definitive diagnosis was hemosuccus pancreaticus due to intraductal mucinouspapillary neoplasm.
