Increased risk of second malignancy in pancreatic intraductal papillary mucinous tumors: Review of the literature

Preoperative predictors of malignancy in pancreatic intraductal papillary mucinous neoplasms.

HYPOTHESIS Malignant intraductal papillary mucinous neoplasms (IPMNs) can be predicted before surgery. DESIGN Retrospective review of a prospectively collected database. SETTING Academic, urban, tertiary care hospital. PATIENTS Sixty-four consecutive patients with a pathological diagnosis of IPMN. INTERVENTIONS All 64 patients underwent surgical intervention for IPMN between December 8,...

Intraductal papillary mucinous tumors of the pancreas

Intraductal papillary mucinous tumors (IPMTs) are benign and malignant lesions that arise from the epithelial lining of main pancreatic duct and/or branch pancreatic ducts, with excessive mucin production (especially hyperplastic/adenomatous variety). Based on the degree of cytoarchitectural atypia on microscopic examination, IPMTs are classified as benign, borderline, carcinoma in situ and inv...

Concomitant pancreatic endocrine neoplasm and intraductal papillary mucinous neoplasm: a case report and literature review

We report a case of concomitant pancreatic endocrine neoplasm (PEN) and intraductal papillary mucinous neoplasm (IPMN). A 74-year-old man had been followed-up for mixed-type IPMN for 10 years. Recent magnetic resonance images revealed an increase in size of the branch duct IPMN in the pancreas head, while the dilation of the main pancreatic duct showed minimal change. Although contrast-enhanced...

Intraductal Papillary Mucinous Tumor Of Common Bile Duct – A Rare Disease Mimicking A Rare Pancreatic Malignancy

Intraductal papillary mucinous neoplasms are known malignant lesions of pancreas but recently a similar tumor has been reported and recognized by WHO in 2010 which involves the bile ducts. The involvement of common bile duct by this malignant tumor is extremely rare. Intraductal papillary mucinous tumors of bile ducts have been found to have much better prognosis than the other cholangiocarcino...
