Intraductal papillary mucinous neoplasms of the pancreas.
BACKGROUND/AIMS Intraductal papillary mucinous neoplasms (IPMNs) are neoplasms of the pancreatic duct epithelium characterized by intraductal papillary growth and thick mucin secretion. Quantities of mucin fill the main and/or branches of pancreatic ducts and cause ductal dilatation. This review encompasses IPMNs, including symptoms, diagnosis, management, and prognosis. METHODS A Pubmed data...
متن کاملIntraductal oncocytic papillary neoplasms of the pancreas.
We describe the clinical and pathologic features of 11 intraductal oncocytic papillary neoplasms of the pancreas, a hitherto unrecognized tumor. The patients were six men and five women, and most of the tumors were in the head (head: body/tail = 8:3). The mean patient age was 62 (range, 39-78), and the average tumor size was 6 cm. Grossly the tumors exhibited mucin-filled cysts containing nodul...
متن کاملIntraductal tubular adenomas (pyloric gland-type) of the pancreas: clinicopathologic features are similar to gastric-type intraductal papillary mucinous neoplasms and different from intraductal tubulopapillary neoplasms
BACKGROUND Intraductal tubular adenoma of the pancreas, pyloric gland type (ITA), is an infrequent intraductal benign lesion located in the main duct and large branch duct of the pancreas. The purpose of this report is to introduce seven new cases and to compare their clinicopathologic features and KRAS mutations to gastric-type intraductal papillary mucinous neoplasms (IPMNs) and intraductal t...
متن کاملManagement of intraductal papillary mucinous neoplasms of the pancreas.
Over the last decade, the diagnosis and treatment of intraductal papillary mucinous tumors (IPMN) of the pancreas has evolved. They represent a spectrum of disease, ranging from benign to malignant lesions, making the early detection and characterization of these lesions important. Several non-invasive and invasive imaging modalities allow adequate visualization of these lesions. Multidetec-tor...
متن کاملIntraductal papillary mucinous neoplasms of the pancreas with concurrent pancreatic and periampullary neoplasms.
BACKGROUND Intraductal papillary mucinous neoplasms (IPMN) have been reported to be associated with concurrent, distinct pancreatic ductal adenocarcinoma (con-PDAC) in about 8% (range, 4-10%) of resected branch duct (BD) lesions. In addition, other pancreatic and ampullary tumors are occasionally diagnosed with IPMN in patients undergoing pancreatic surgery. The objective of this study is to de...
