Cholangiocarcinomas (CCAs) are rare malignancies that originate from the epithelial cells of the bile ducts. It is the second most-common primary liver cancer after hepatocellular carcinoma. Recent epidemiologic studies have shown that the overall incidence and mortality rates of CCAs are increasing. Diagnosis is often challenging due to the difficulty in getting tissue/cytology for confirmation, and it comprises a combination of cross-imaging, tumor markers, histology, and cholangiography. Surgery involving major resections of liver, bile duct, pancreas, and at times adjacent vessels is the only chance for cure. Evaluation should be focused on the assessment of tumor resectability, hepatic reserve, and patient physiological fitness for major surgery. In patients not fit for major surgery, biliary drainage for jaundice is an appropriate intervention and if there is histologic confirmation of a CCA, palliative therapies focused on local and systemic disease control should be considered. The endeavor to expand the indications for liver transplantation reflects the efforts to provide an effective form of therapy for a previously untreatable disease. A multidisciplinary specialized approach should be the platform for providing the best comprehensive care for these patients.

Hepatitis C virus (HCV) infected patients are known to be at risk of developing liver complications i.e. cirrhosis and liver cancer. However, the risks of morbidity and mortality are underestimated because they do not take into account non-liver consequences of chronic hepatitis C virus infection. Numerous extrahepatic manifestations have been reported in up to 74% of patients, from perceived to disabling conditions. The majority of data concern hepatitis C virus-related autoimmune and/or lymphoproliferative disorders, from mixed cryoglobulinaemia vasculitis to frank lymphomas. More recently, other hepatitis C virus-associated disorders have been reported including cardiovascular, renal, metabolic, and central nervous system diseases. This review aims to outline most of the extrahepatic manifestations that are currently being investigated, including some of autoimmune and/or lymphoproliferative nature, and others in which the role of immune mechanisms appears less clear. Beyond the liver, hepatitis C virus chronic infection should be analyzed as a multifaceted systemic disease leading to heavy direct and indirect costs. The accurate consideration of extrahepatic consequences of such a systemic infection significantly increases the weight of its pathological burden. The need for effective viral eradication measures is underlined.

During hepatitis C virus (HCV) chronic infection, extrahepatic manifestations are frequent and polymorphous. This article reports on a large cohort of patients with HCV-related autoimmune or lymphoproliferative disorders, from mixed cryoglobulinemia vasculitis to frank lymphomas. The relationship between HCV infection and such immune-related diseases has been formally demonstrated by epidemiological, clinical, immunological and pathological data, and results of therapeutic trials. More recently, other nonliver-related HCV disorders have been reported, including cardiovascular (i.e. stroke, ischemic heart disease), renal, metabolic and central nervous system diseases. For these manifestations, most evidence comes from large epidemiological studies; there is a need for mechanistic studies and therapeutic trials for confirmation. Beyond the risk of developing liver complications, that is, cirrhosis and liver cancer, patients with HCV infection have an increased risk of morbidity and mortality related to nonliver diseases. HCV chronic infection should be analyzed as a systemic disease in which extrahepatic consequences increase the weight of its pathological burden. The need for effective viral eradication measures is underlined.
