BACKGROUND: Intrahepatic sarcomatoid chonalgiocarcinoma (s-CCC) is an extremely rare disease, accounting for less than 1% of hepatobiliary system malignancies, and its pathophysiology is not well known. On the hypothesis that its clinical, serologic, or radiologic diagnosis are not fully understood and its prognosis is poor, we investigated the distinguishing features of s-CCC compared with those of intrahepatic bile duct adenocarcinoma [cholangiocellular carcinoma (CCC)] in patients from a single center...

Importance: Anastomotic biliary complications (ABCs) constitute the most common technical complications in liver transplant (LT). Given the ever-increasing acuity of LT, identification of factors contributing to ABCs is essential to minimize morbidity and optimize outcomes. A detailed analysis in a patient population undergoing high-acuity LT is lacking. Objective: To evaluate the rate of, risk factors for, and outcomes of ABCs and acuity level in LT recipients...

BACKGROUND: Intraductal tubular papillary neoplasm (ITPN) displays a very rare subtype of epithelial neoplasms of the pancreas. ITPN is characterized by intraductal tubulopapillary growth and cellular dysplasia. In contrast to intraductal papillary neoplasm (IPMN) no overt epithelial mucin production is observed. To date, little is known about ITPN and particularly about pancreatic cancer arising in this tumor entity. CASE PRESENTATION: A 68-year-old male presented at our hospital with a distal bile duct occlusion suspicious for adenocarcinoma of the pancreatic head...

Hepatocellular carcinoma (HCC) is a highly malignant tumor found in the bile duct epithelial cells, and the second most common tumor of the liver. However, the pivotal roles of most molecules of tumorigenesis in HCC are still unclear. Hence, it is essential to detect the tumorigenic mechanism and develop novel prognostic biomarkers for clinical application. The data of HCC mRNA-seq and clinical information from The Cancer Genome Atlas (TCGA) database were analyzed by weighted gene co-expression network analysis (WGCNA)...

Introduction: Thermal ablation of liver tumours is an established technique used in selected patients with relatively small tumours that can be ablated with margin. Thermal ablation methods are not advisable near larger bile ducts that are sensitive to thermal injury causing strictures and severe morbidity. Irreversible electroporation (IRE) has the possibility to treat these tumours without harming the bile tree. The method is relatively new and has been proven to be feasible and safe with promising oncological results...

BACKGROUND/AIMS: Loss of hepatocyte nuclear factor-4α (HNF4α), a critical factor driving liver development and differentiation, is frequently associated with hepatocellular carcinoma (HCC). Our recent data revealed that HNF4α level was decreased in mouse and human HCCs with activated β-catenin signaling. In addition, increasing HNF4α level by miR-34a inhibition slowed tumor progression of β-catenin activated HCC in mice. METHODS: We generated a Hnf4aflox/flox/ Apcflox/flox /TTR-CreERT 2 (Hnf4a/Apc∆Hep ) mouse line and evaluated the impact of Hnf4a disruption on HCC development and liver homeostasis...

Hepatocellular carcinoma (HCC) is heterogeneous in terms of its biological nature. Various factors related to its biological nature, including size, multifocality, macroscopic morphology, grade of differentiation, macro/microvascular invasion, bile duct invasion, intra-tumoral fat and molecular factors, and their value as prognostic imaging biomarkers have been reported. And recently, genome-based molecular HCC classification correlated with clinical outcome has been elucidated. The imaging biomarkers suggesting a less aggressive nature of HCC are smaller size, solitary tumor, smooth margin suggesting small nodular type with indistinct margin and simple nodular type with distinct margin, capsule, imaging biomarkers predicting early or well-differentiated grade, intra-tumoral fat detection, and low fluorodeoxyglucose (FDG) accumulation...

BACKGROUND: Biliary papillomatosis (BP) is a rare disease characterized by multiple papillary adenomas in the intrahepatic and extrahepatic biliary tree and has a high risk of malignant transformation. Early diagnosis and treatment for BP are challenges, as it spreads along the biliary tract. A radical resection with an adequate resection margin is advocated in patients with malignant BP. CASE SUMMARY: We report a case of BP with malignant transformation in a 52-year-old female patient who presented with emaciation, severe malnutrition, and a T-tube for biliary drainage that was placed for almost 2 years at the time she visited us...

BACKGROUND: Infiltrative adenosquamous carcinoma (ASC) of the extrahepatic bile duct is reported infrequently, which is an unusual variant of the ordinary adenocarcinoma. The simultaneous development of ASC and cystadenocarcinoma in the extrahepatic biliary tree is rare. In addition, the accurate preoperative diagnosis of concomitant carcinoma in the multiple biliary trees at an early stage is often difficult. Thus, awareness of the risk of the multiplicity of biliary tumors is perhaps the most important factor in identifying these cases...

AIM: To identify magnetic resonance imaging (MRI) features for differentiating hepatocellular carcinoma (HCC) from intrahepatic cholangiocarcinoma (IHCC) and summarise their diagnostic accuracy. MATERIALS AND METHODS: PubMed and EMBASE were searched for studies that employed MRI features to differentiate HCC from IHCC. Overlapping descriptors used to denote the same imaging finding in different studies were subsumed under a single feature. The pooled diagnostic accuracies, including the diagnostic odds ratios (DORs) and 95% confidence intervals (CIs) of the identified features, were calculated using a bivariate random-effects model...

A 76-year-old woman with lower bile duct carcinoma underwent subtotal stomach-preserving pancreaticoduodenectomy (SSPPD)after percutaneous transhepatic biliary drainages(PTBD). Nine months after the operation, chest computed tomography revealed a mass in the subcutis of the right chest wall, which was a different lesion from that in the PTBD site. The aspiration biopsy cytology and needle biopsy indicated no malignant findings. However, the mass was growing and was suspected to be a metastasis of bile duct cancer...

The patient was an 86-year-old man who was admitted with obstructive jaundice. Computed tomography revealed a tumor in the hilar choledochus with peripheral hepatic duct dilatation. Endoscopic cholangiography (ERC) demonstrated the defect in the choledochus. Brushing cytology during ERC showed Orange-G-philic keratinized atypical cells, which led to a diagnosis of squamous cell carcinoma. Chemotherapy with tegafur-gimeracil-oteracil potassium was ineffective and was discontinued due to adverse effects. The patient died 5 months after the diagnosis and autopsy revealed tubular adenocarcinoma of the hilar bile duct with squamous cell carcinoma component...

Primary neuroendocrine tumors originating from the extrahepatic bile duct are rare. Among these tumors, large cell neuroendocrine carcinomas (NECs) are extremely rare. A 59-year-old man was admitted to Sanggye Paik Hospital with jaundice that started 10 days previously. He had a history of laparoscopic cholecystectomy, which he had undergone 12 years previously due to chronic calculous cholecystitis. Laboratory data showed abnormally elevated levels of total bilirubin 15.3 mg/dL (normal 0.2-1.2 mg/dL), AST 200 IU (normal 0-40 IU), ALT 390 IU (normal 0-40 IU), and gamma-glutamyl transferase 1,288 U/L (normal 0-60 U/L)...
