BACKGROUND: Biphenotypic hepatocellular carcinoma-cholangiocarcinoma (HCC-CC) is an uncommon primary liver neoplasm. Due to limitations in radiologic imaging for the diagnosis of this condition, biopsy is a common method for diagnosis, which is invasive and holds potential complications. To identify alternative means for obtaining the diagnosis and assessing the prognosis of this condition, we evaluated biomarkers for biphenotypic HCC-CC using a genetic database. METHODS: To evaluate the genetic associations with each variable we utilized GeneCards(®), The Human Gene Compendium (http://www...

BACKGROUND: Combined hepatocellular-cholangiocarcinoma (cHCC-CC) is an uncommon primary liver malignancy and little known about the clinical and imaging characteristics of cHCC-CC. We aim to define the demographics, imaging features of cHCC-CC on contrast-enhanced ultrasound (CEUS) and contrast-enhanced computed tomography (CT) in this study. METHODS: From January 2005 to December 2014, 45 patients with pathologically proven cHCC-CC who underwent preoperative CEUS and 43 patients who had additional CT scan in our institution were included...

OBJECTIVE: The purpose of this study was to determine the frequency with which biphenotypic primary liver carcinoma (also called hepatocholangiocarcinoma) may be misclassified as hepatocellular carcinoma (HCC) when only Liver Imaging Reporting and Data System (LI-RADS) major features are used and after consideration of ancillary features. MATERIALS AND METHODS: A review of all pathologically proven biphenotypic primary liver carcinomas diagnosed at one institution from 2006 to 2014 was performed...

Biphenotypic (hepatobiliary) primary liver carcinomas [B(H-B)PLCs] are rare tumors with features of both hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC). These tumors are associated with a poor overall prognosis and treatment is not well defined. Research over the past 20 years has identified aberrations in several molecular pathways, including epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF) in hepatocellular and biliary tract cancers. These discoveries led to the evaluation of targeted therapies, such as tyrosine kinase inhibitors, for the treatment of HCC and ICC...

BACKGROUND: Primary liver carcinomas with hepatocellular and cholangiocellular differentiation (b[HB]-PLC) are rare. Surgery offers the best prognosis, but there is a paucity of literature to guide therapy for patients with advanced or unresectable disease. This study aimed to evaluate outcomes of hepatic-directed therapy compared with those of systemic chemotherapy and surgery. METHODS: A retrospective evaluation of patients with b(HB)-PLC from 1 January 2008 to 1 September 2014 was conducted...

Hepatocellular carcinoma can be diagnosed on a needle biopsy of the liver; however, uncertainty may arise because of the inherent complexity of liver histology. This article aims to provide practicing pathologists with tools for the approach to mass-directed liver biopsies clinically concerning for hepatocellular carcinoma. The examination of routine hematoxylin-eosin stains and the use of ancillary histochemical and immunohistochemical stains are discussed. Sections reviewing liver carcinoma with biphenotypic differentiation and the challenge of dysplastic nodules are included...

Combined hepatocellular-cholangiocarcinoma (CHC), also referred to as primary liver carcinoma (PLC) with biphenotypic differentiation, is an increasingly recognized subtype of malignant PLC encompassing varying morphologic forms thought to arise either from progenitor cell lineage or dedifferentiation of mature liver cells. Tumor cells express both biliary and hepatocellular markers by immunohistochemistry, and may also express progenitor cell and stem cell markers. Due to the relative rarity of this tumor type, little is known about the risk factors, imaging appearance, or prognosis...

OBJECTIVE: The purpose of this study was to evaluate the diagnostic accuracy of preoperative imaging for diagnosis of combined hepatocellular cholangiocarcinoma tumors and to evaluate the clinical and imaging features and demographics of patients presenting to our institution with such tumors. MATERIALS AND METHODS: From January 2001 to January 2011, 29 patients presented with pathologically proven combined hepatocellular cholangiocarcinoma tumors to our institution...

The synchronous or metachronous coexistence of gastrointestinal stromal tumors (GISTs) with solid and hematologic neoplasms has been addressed in a non-transplant population. However, the association with primary hepatic neoplasms and leukemias is uncommon. Scarce data exist considering association of GISTs and other neoplasms in a transplant population where long-term immunosuppression carries the additional burden of de novo malignancy. We present a case of posttransplant metachronous GIST and acute biphenotypic leukemia in a patient transplanted for intrahepatic cholangiocellular carcinoma, emphasizing the possible link between mechanisms of carcinogenesis and influence of other factors upon their development...

The biliary tract is a very rare site for the occurrence of extrapulmonary small cell carcinoma. A 68-year-old Japanese female was being followed up for autoimmune hepatitis, and was referred to our hospital because segmental intrahepatic bile duct dilation was found on routine imaging studies, suggesting intrahepatic cholangiocarcinoma. She underwent left lobectomy of the liver and concomitant resection of the caudate lobe. Microscopic examination of the explanted liver showed a primary composite tumor comprising small cell and mucinous carcinomas that originated in the intrahepatic bile duct...

A 48 year-old African American woman presented to her physician complaining of a rapidly evolving epigastric and right upper quadrant abdominal pain. A PET-CT of the abdomen and pelvis demonstrated hypermetabolic, polypoid masses within the gallbladder and several tumors in the left lobe of the liver for which she underwent diagnostic laparoscopy. The gallbladder revealed a 3.5 × 3.3 × 2.4 tan-brown exophytic mass located at the fundus and growing into the lumen with multiple contiguous papillary projections arising from the mucosal surface...

Combined hepatocellular and cholangiocarcinoma is a rare form of primary hepatic carcinoma. We present a case of combined hepatocellular and cholangiocarcinoma coexisting with hepatolithiasis in a 53-year-old woman. The tumor was detected during surgery for the treatment of intrahepatic stones. A left hepatectomy was performed. A histologic examination of the specimen revealed typical features of combined hepatocellular and cholangiocarcinoma. Immunohistochemical analyses showed a biphenotypic antigen expression profile of the tumor cells...

Fibrolamellar carcinoma (FLC), a variant of hepatocellular carcinoma (HCC), very rarely occurs in association with cholangiocarcinoma (CC). This report describes the first case of FLC coexisting with CC (FLC-CC) from Japan. Although the major part of the tumour located in the right lobe of the liver showed the typical features of FLC, CC was admixed with the FLC, not only in the primary hepatic tumour, but also in the lymph node metastases. Immunohistochemical analysis revealed that, although carcinoembryonic antigen (CEA), which can be detected with monoclonal antibodies in the cytoplasm and the cell surface of CC cells but not HCC cells, was expressed in only the CC cells in the primary tumour, it was expressed extensively in the cytoplasm of both CC and FLC cells in the metastatic and recurrent tumours...

Combined hepatocellular-cholangiocarcinoma (CHC) forms a small but significant proportion of primary liver carcinomas. However, its diagnostic features are not well established, and this has possibly contributed to the variability in its reported clinical outcome in the literature. Many such tumors with features intermediate between hepatocellular carcinoma and cholangiocarcinoma (CC) may have been considered CC in the past based on positivity for "biliary differentiation" cytokeratins and the lack of availability of highly sensitive and specific hepatocellular markers...
