title: Intraductal papillary mucinous neoplasm of the pancreas presenting as acute pancreatitis.
abstract: Intraductal papillary mucinous neoplasms are rare pancreatic exocrine tumors with distinct clinicopathologic features. They usually present with a long history of chronic pancreatitis-like symptoms, which are often associated with weight loss, diarrhea, and malabsorption. We report a case of benign intraductal papillary mucinous neoplasm with focal squamous metaplasia presenting as acute necrotizing pancreatitis. The clinicopathologic features are discussed in a brief review of the literature.
