The prevalence of pancreatic cysts has increased significantly over the last decade, partly secondary to quality and frequency cross-sectional imaging. While majority never progress cancer, a small number will need be followed. management can both confusing intimidating due multiple guidelines with varying recommendations. Despite differences in specifics guidelines, they all agree on several h...

BACKGROUND AND STUDY AIMS Endoscopic ultrasound (EUS) surveillance of patients with mucinous pancreatic cysts relies on the assessment of morphologic features suggestive of malignant transformation. These criteria were derived from the evaluation of surgical pathology in patients with pancreatic cysts who underwent surgery. Reliability of these criteria when evaluated by EUS in identifying lesi...

The real prevalence of pancreatic cystic lesions remains unknown. The malignant potential of some of these lesions remains a cause for significant concern. Thus, it is mandatory to develop a strategy to clearly discriminate those cysts with a potential for malignant transformation from those that do not carry any significant risk. Intraductal papillary mucinous neoplasms and mucinous cystadenom...

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...

IPMN: intraductal papillary mucinous neoplasm POIKTMP: hereditary fibrosing poikiloderma with tendon contractures, myopathy, and pulmonary fibrosis RTS: Rothmund-Thomson syndrome H ereditary fibrosing poikiloderma with tendon contractures, myopathy, and pulmonary fibrosis (POIKTMP [MIM#615704]) is an extremely rare syndromic form of autosomal dominant poikiloderma. This genetic disorder was fir...

Here we report a case of benign intraductal papillary-mucinous neoplasm (IPMN) of the pancreas containing two major subtypes. A 73-year-old man underwent pancreatoduodenectomy for a cystic mass, 5.0 cm in diameter. Histopathologic examinations revealed that IPMN was composed of gastric-type adenoma and intestinal-type borderline lesion. Marked intraluminal nodular growth was observed in the cen...

A 74-year-old man suffered from jejunal perforation and adhesion to sigmoid colon due to adenocarcinoma associated with intraductal papillary mucinous neoplasm (IPMN) arising in a jejunal heterotopic pancreas. The jejunal lesion showed direct extension to the sigmoid colon, which was mistaken as sigmoid colon cancer by surgeons. Malignant transformation is a rare complication of a heterotopic p...

Cystic neoplasms of the liver are divided into two types: mucinous cystic neoplasm and cystic intraductal papillary neoplasm of the bile duct. We herein report two cases of cystic and papillary neoplasm of the liver which differed from the abovementioned types. Case  1. A 70-year-old man. Radiologically, a cystic tumor measuring 20 mm in diameter was found at the hepatic hilum. Right hepatectom...
