title: Autoimmune hepatitis with giant-cell transformation.
abstract: OBJECTIVE
  Giant-cell hepatitis (GCH), also known as postinfantile or syncytial giant cell hepatitis, is a frequent pattern of liver injury in the neonate, primarily seen in the first three months of life. Few cases in adults have been reported, some of them associated to autoimmune diseases such as autoimmune hepatitis.
  
  
  METHODS
  We present a case of autoimmune hepatitis with giant cell transformation in a 39 year old male with polyarthritis. We discuss his clinical presentation and course. We made a review of the literature of agents associated to this diagnosis, the mechanisms involved in the formation of giant hepatocytes, the histological findings, clinical course, treatment options and prognosis of this rare entity.
  
  
  CONCLUSIONS
  In conclusion, the clinical course varies from normalization of hepatic histology to progression to cirrhosis and liver failure. The prognosis is dictated by the underlying liver disease and in the setting of autoimmune hepatitis the clinical course is usually severe with most of the patients progressing to cirrhosis. Prolonged treatment with corticosteroids and immunosuppressants is usually effective in rendering the cirrhosis inactive.
