Intraductal papillary-mucinous tumors of the pancreas are a category of recently described tumors of the exocrine pancreas. They were reported for the first time in 1982 [1] when Ohashi et al., based on the findings of four cases of mucous secreting pancreatic cancer, theorized that those cases belonged to a group of tumors with different features with respect to common pancreatic cancer. Some ...

Pancreatic tuberculosis is rare and can occur in the absence of evidence of tuberculosis elsewhere in the body. Here we review the radiological appearance of pancreatic tuberculosis and compare it with other cystic pancreatic lesions, including common lesions (pseudocysts, serous or mucinous cystadenomas, intraductal papillary mucinous neoplasm) and rare lesions such as solid pseudopapillary tu...

The increasing interest of the oncology community in tumour classification and prediction of outcome to targeted therapies has put emphasis on an improved identification of tumour types. Colorectal mucinous adenocarcinoma (MC) is a subtype that is characterized by the presence of abundant extracellular mucin that comprises at least 50% of the tumour volume and is found in 10-15% of colorectal c...

OBJECTIVES Annular pancreas is a rare congenital anomaly characterized by pancreatic tissues wrapping completely or incompletely around the descending duodenum. In most patients with annular pancreas, onset occurs in early childhood. Adults with annular pancreas are prone to duodenal ulcers and pancreatitis. Intraductal papillary mucinous neoplasm (IPMN) is a type of papillary mucinous secretor...

A 65-year-old man was hospitalized due to an abdominal tumor. Several imaging studies showed multilocular tumors in the right hepatic lobe and in the pancreatic head, 4 and 7 cm in size, respectively. The hepatic tumor rapidly grew to 9 cm in 4 weeks, associated with a rapid increase in the serum carcinoembryonic antigen level from 125 ng/ml to 1,000 ng/ml. The pathologic diagnosis of the resec...

OBJECTIVE To determine the occurrence of new disease in the pancreatic remnant after resection for intraductal papillary mucinous neoplasms. DESIGN A longitudinal level II cohort study. SETTING Virginia Mason Medical Center, Seattle, Washington. PATIENTS The primary cohort was a "resection cohort" of 203 patients who underwent partial pancreatic resection for an intraductal papillary muci...

Pancreatic adenocarcinoma is the fifth leading cause of cancer death in the United States. Mutations in the K-ras oncogene occur in 85% of pancreatic adenocarcinomas and have also been identified in 75% of pancreatic ducts with mucinous cell hyperplasia seen in association with chronic pancreatitis. We identified K-ras mutations in 65% of duct lesions associated not only with chronic pancreatit...

Roughly 10% – 20% of pancreatic cancer patients are candidates for curative intent surgical treatment. In the 2000s, many studies showed similar survival rates comparing surgery with or without vein resection and reconstruction. The aim was to identify best method venous This a retrospective cohort study. A total 1 375 undergoing pancreatectomy between 2005 2018 were identified. Patients combin...

Pancreatic cystic lesions (PCLs) may represent malignant or premalignant neoplasms and require diagnostic evaluation. Patient’s demographics and clinical presentation should be considered when diagnosing PCLs. Radiologically, location, ductal relation, external contour, wall, and septal enhancement give important clues for each type of lesion. Imaging features that suggest a high malignancy ris...

BACKGROUND Cystic tumour of the pancreas are infrequent and malignancy of the pancreas during pregnancy is extremely rare. Mucinous cystoadenomas is the most frequent cystic pancreatic neoplasm and it is seen mainly in women suggesting a sex hormone influence. Its presentation during pregnancy is extremely rare and entails difficulties in diagnosis and therapy. CASE REPORT A 28 year old woman...
