title: [Etiology and outcome of liver granulomatosis: a retrospective study of 21 cases].
abstract: OBJECTIVE
  To assess the etiologies and outcome of liver granulomatosis.
  
  
  METHODS
  We analyzed all consecutive liver granulomatosis diagnosed in our internal medicine department from 2000 to 2008.
  
  
  RESULTS
  Among 471 liver biopsies, 21 disclosed evidence of liver granulomatosis (4.5%), in sixteen women (76%) and five men, with a median age of 41years. Thirteen were caucasians (62%). At the time of diagnosis, six (28.5%) had isolated abnormal liver function tests, and fifteen (71.4%) presented with clinical manifestations. The underlying cause was identified in 18 cases (85.7%). Eleven (52.3%) were systemic diseases: five (23.8%) primary biliary cirrhosis, two (9.5%) primary sclerosing cholangitis, two (9.5%) common variable immunodeficiency, one (4.7%) Sjögren's syndrome, and one (4.7%) Behçet's disease. Two (9.5%) patients had sarcoidosis. Three (14.3%) liver granulomatosis were of infectious origin (tuberculosis, schistosomiasis, and hepatitis C virus), two (9.5%) were neoplastic (Hodgkin's lymphoma and liver cell adenoma), and three (14.3%) were idiopathic. With a median of 38 months of follow-up, four patients (19%, two common variable immunodeficiency and two sarcoidosis) developed portal hypertension, independently of cirrhosis. One patient died of cryptococcosis.
  
  
  CONCLUSIONS
  In accordance with other European studies, systemic diseases are the main causes of hepatic granulomas. Liver granulomatosis related to common variable immunodeficiency and sarcoidosis are at risk of portal hypertension.
