BACKGROUND The prevalence of carcinoma in main-duct intraductal papillary mucinous neoplasm (IPMN) is high, and surgical resection is recommended for all patients with a main-duct IPMN. RESULTS A main-duct IPMN with typical imagings including protruding lesions in the dilated main pancreatic duct was resected, but the histology was intraductal papillary mucinous adenoma of the pancreas. DIS...

In recent years, the disease concept of intraductal papillary neoplasm of the bile duct (IPNB) has been attracting attention as a biliary lesion that is morphologically similar to intraductal papillary mucinous neoplasm (IPMN), which is considered to be a counterpart of IPMN. However, there are few reports on IPNB, and a consensus regarding the features of this disease is thus lacking. We exper...

BACKGROUND Although intraductal papillary mucinous neoplasm (IPMN) of the pancreas is acceptable as a distinct disease entity, the concept of mucin-secreting biliary tumors has not been fully established. CASE PRESENTATION We describe herein a case of mucin secreting biliary neoplasm. Imaging revealed a cystic lesion 2 cm in diameter at the left lateral segment of the liver. Duodenal endoscop...

Context Intraductal Papillary Mucinous Neoplasm of the pancreas is an increasingly diagnosed neoplasm that rarely penetrates adjacent organs. Case report A sixty-year-old asymptomatic male was seen for evaluation of iron deficiency anemia. Patient was found to have a mucin secreting tumor during esophagogastroduodenoscopy. Computed tomography scan showed an enlarged pancreas with numerous focal...

Like other forms of laparoscopic surgery, laparoscopic pancreaticoduodenectomy (Lap-PD) is a minimally invasive procedure that can greatly reduce bleeding during surgery. We performed Lap-PD for a case of intraductal papillary mucinous neoplasm. To remove the resected tissue from the body, we made a small incision directly above the line of transection of the distal pancreas (the cut stump). Th...

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...

Among pancreatic cystic lesions, mucinous neoplasm (MCN) and intraductal papillary (IPMN) of the pancreas are precursor lesions adenocarcinoma. IPMN is characterized by proliferation mucin-producing epithelial cells that exhibit various degrees dysplasia. classified as main duct type (MD-IPMN), mixed branch (BD-IPMN) according to location involvement, into four histological subtypes (gastric, i...

CT: computed tomography EUS: endoscopic ultrasound scan IPMN: intraductal papillary mucinous neoplasm MRCP: magnetic resonance cholangiopancreatography MPD: main pancreatic duct INTRODUCTION Pancreatic panniculitis is a rare skin manifestation of pancreatic disease. It is believed to result from seepage of pancreatic enzymes into the systemic circulation, which leads to skin and occasionally jo...
