Pancreatic anaplastic carcinoma (PAC) is rare and has an aggressive clinical course. We report an autopsy case of PAC focusing on the cytopathological characteristics of the tumor and immunocytochemical staining for vimentin, E-cadherin, and zinc finger E-box binding homeobox 1 (ZEB1), which markers are associated with epithelial markers of epithelial-mesenchymal transition (EMT). A 50-year-old woman presented to our hospital with a chief complaint of jaundice. A pancreatic head tumor and multiple liver nodules were detected on abdominal computed tomography...

OBJECTIVES: Cholangiocarcinoma (CCA) is a biliary malignancy found primarily in adults. The incidence of CCA in children is unknown. The aim of this study was to describe characteristics of CCA in children and adolescents. METHODS: Using the Surveillance, Epidemiology, and End Results Program (SEER 18) database, we identified incident cases of CCA diagnosed at <20 years of age during the period of 1973-2013. Additionally, we reviewed published case reports describing pediatric patients with CCA...

We report a case of a mucin-producing intraductal papillary neoplasm of the intrahepatic bile duct (M-IPNB) diagnosed over a period of 6 years. A 64-year-old man underwent follow-up evaluations for an abdominal aortic aneurysm at our hospital. In 2009, a computed tomography (CT) scan revealed a simple hepatic cyst in segment 3 of the liver. Annual CT scans initially showed almost no change in the size or shape of the cyst. The cystic lesion, which measured 5 cm in 2014, had increased to 11 cm by 2015, and a solid component was detected within the cyst...

BACKGROUND: Surgical site infections (SSI) are one of the most common complications after hepato-pancreato-biliary surgery. Infectious complications may lead to an associated immune-modulatory effect that inhibits the body's response to cancer surveillance. We sought to define the impact of SSI on long-term prognosis of patients undergoing surgical resection of extrahepatic biliary malignancies (EHBM). METHODS: Patients undergoing surgery for EHBM between 2000 and 2014 were identified using a large, multi-center, national cohort dataset...

BACKGROUND/AIM: Previous studies on the accuracy of 5-aminolevulinic-acid-mediated photodynamic diagnosis (5-ALA PDD) have been reported for various cancers and brain surgery. However, biliary tract cancer is rare. Therefore, 5-ALA PDD has not been fully evaluated in biliary tract cancers. Small biliary tract cancer lesions such as peritoneal dissemination, liver metastases, and lymph node metastases are negative prognosticators in patients with biliary cancer. The purpose of this exploratory study was to determine if 5-ALA PDD could detect small biliary tract cancer lesions in murine models of biliary cancers...

Colorectal cancer is a leading cause of death worldwide. The liver is the most common site of distant metastases and surgery is the only potentially curative treatment, although recurrence following surgery is high. In order to define prognosis after surgery, many histopathological features have been identified in the primary tumor. In turn, pathologists routinely report specific findings to guide oncologists about the decision to recommend adjuvant therapy. In general, the pathological report of resected colorectal liver metastases is limited to confirmation of the malignancy and details regarding the margins status...

OBJECTIVES: Endoscopic drainage of complex hilar tumors has generally resulted in poor outcomes. Drainage of >50% of liver volume has been proposed as optimal, but not evaluated using long multifenestrated plastic stents (MFPS) or self-expanding metal stents (SEMS). We evaluated outcomes of endoscopic drainage of malignant hilar strictures using optimal strategy and stents, and determined factors associated with stent patency, survival, and complications. METHODS: Cross-sectional study was conducted at an academic center over 5 years...

Bile duct hamartoma (BDH) is a rare liver disease with a rising incidence in recent years. A retrospective study on BDH patients between June 2007 and December 2015 was conducted. All the medical records, including clinical, imaging and pathological characteristics, were retrieved. Follow-up data were obtained by telephone communication. The majority of the patients had no symptoms and the laboratory tests were normal. The appearance on ultrasound examination was variable. The lesion exhibited low density on plain computed tomography and no enhancement in 4 cases, and inhomogeneous enhancement in 1 case...

BACKGROUND: Locoregional bridging treatments are commonly applied in hepatocellular carcinoma (HCC) patients prior to liver transplantation to prevent tumor progression during waiting time. It remains unknown whether pre-transplant radioembolization treatment may increase the prevalence of hepatic artery and biliary complications post-transplant. METHODS: We performed a retrospective review of 173 consecutive HCC patients who underwent liver transplantation at our transplant center between January 2007 and December 2016...

Pediatric liver transplantation (LTx) is increasingly performed for rare unresectable liver malignancies other than hepatoblastoma (HBL). PURPOSE: We performed a retrospective review of outcomes after LTx for malignancy in the multi-center US Scientific Registry for Transplant Recipients (SRTR, n=677, 1987-2015). We then reviewed the Children's Hospital of Pittsburgh (CHP, n=74, 1981-2014) experience focusing on LTx for unresectable hepatocellular cancer (HCC), non-HBL embryonal tumors (EMB) and metastatic liver tumors (METS)...

We report a case of a 48-year-old female patient, who presented with abdominal pain, jaundice, and lack of appetite. Ultrasound showed intrahepatic biliary dilatation with retroperitoneal lymphadenopathy. Further magnetic resonance cholangiopancreatography detected Klatskin tumor. Computed tomography (CT) confirmed the Klatskin tumor with liver metastases and retroperitoneal lymphadenopathy. Biopsy from the hepatic lesion identified mucinous adenocarcinoma, likely originating from bile ducts. Endoscopic retrograde cholangiopancreatography was performed 3 times with stents placed in the left and right hepatic bile ducts...

In the context of medical three-dimensional (3D) printing, in addition to 3D reconstruction from cross-sectional imaging, graphic design plays a role in developing and/or enhancing 3D-printed models. A custom prototype modular 3D model of the liver was graphically designed depicting segmental anatomy of the parenchyma containing color-coded hepatic vasculature and biliary tree. Subsequently, 3D printing was performed using transparent resin for the surface of the liver and polyamide material to develop hollow internal structures that allow for passage of catheters and wires...

Primary hepatic lymphoma (PHL) presenting with obstructive jaundice is rare and can mimic a preoperative diagnosis of cholangiocarcinoma. We should consider PHL in patients with radiological hepatic disease with normal serum alpha-fetoprotein and carcinoembryonic antigen levels, and elevated lactate dehydrogenase. We present the case of a 67-year-old male with no significant medical history presented with abdominal pain, jaundice, fever, and abnormal liver function tests. Abdominal sonography and computed tomography scan suggested a diagnosis of obstructive jaundice and cholangitis due to cholangiocarcinoma (Klatskin tumor)...

Cholangiocarcinoma (CCA) is an aggressive cancer arising from epithelial cells of the bile duct. Most patients with CCA have an unresectable tumor at the time of diagnosis. In Western countries, the risk of CCA increases in patients with primary sclerosing cholangitis, whereas liver fluke infection appears to be the major risk factor for CCA in Asian countries. A diagnosis of liver fluke infection often relies on stool samples, including microscopic examination, polymerase chain reaction-based assays, and fluke antigen detection...
