Although incidental pancreatic cystic neoplasms are being diagnosed with increasing frequency, little is known about the accurate prevalence of pancreatic cysts in the general population. The aims of this study were to evaluate the crude prevalence rate of pancreatic cystic neoplasms in asymptomatic healthy adults, and calculate the age- and sex-adjusted nationwide prevalence rate.A total of 21...

A 42-years-old woman had undergone operation for cholecochal cyst with gallbladder cancer 9 years ago. Pathology revealed a polypoid mass in the gallbladder with liver infiltration as poorly differentiated adenocarcinoma. Computed tomography, magnetic resonance cholangiopancreatography, and endoscopic ultrasound showed a newly developed suspected solid nodule in the peripheral portion of cystic...

HISTOLOGICAL TUMOUR TYPE (Note 7) Hepatocellular carcinoma Hepatocellular carcinoma, fibrolamellar variant Cholangiocarcinoma Combined hepatocellular – cholangiocarcinoma Intraductal papillary neoplasm with an associated invasive carcinoma Mucinous cystic neoplasm with an associated invasive carcinoma Undifferentiated carcinoma Carcinoma, type cannot be determined mm Intrahepatic Cholangiocar...

Gastric duplication represents a very rare entity in the adult population. Most of the symptoms are due to the presence of ectopic gastric mucosa (30-35% of cases), gastrointestinal bleeding or perforation or neoplasm formation. We report a case of gastric duplication in an adult mimicking a mucinous cystic neoplasm of the pancreas.

BACKGROUND Solid pancreatic tumors such as pancreatic ductal adenocarcinoma (PDAC), solid pseudopapillary tumor (SPT), and pancreatic endocrine tumor (PET) may occasionally manifest as cystic lesions. In this study, we have put together our accumulated experience with cystic manifestations of various solid tumors of the pancreas. METHODS From 2000 to 2006, 376 patients with pancreatic solid t...

BACKGROUND Mucinous cystic neoplasms arise in the ovary and various extra-ovarian sites. While their pathogenesis remains conjectural, their similarities suggest a common pathway of development. There have been rare reports involving the mesentery as a primary tumour site. CASE PRESENTATION A cystic mass of uncertain origin was demonstrated radiologically in a 22 year old female with chronic ...

Intrahepatic and extrahepatic cholangiocarcinomas develops through a multistep carcinogenesis sequence and they are preceded by precursor lesions. Precursors of malignant neoplasm are identified in various organs including uterine cervix, gastrointestinal tract and breast. Identification of these precursor lesions are important in that they need minimal treatment or they are good indicator of d...
