[A puzzling case of portal hypertension in a patient with human immunodeficiency and hepatitis C virus co-infection].

The case of a human immunodeficiency virus (HIV) and hepatitis C virus (HCV)-coinfected patient with a medical history of deep venous thrombosis is presented. A liver biopsy, performed for unexpected portal hypertension, showed vascular lesions presenting as nodular regenerative hyperplasia. Vascular liver diseases seem to be a new cause of chronic liver disease in HIV-infected patients receiving combined antiretroviral therapy. The syndrome of HIV-associated liver vasculopathy is discussed.
