giant cell hepatitis (redirected from Giant cell transformation of liver)
hepatitis in the neonatal period presumed to be due to any of a variety of causes, chiefly viral; characterized by direct and indirect bilirubinemia, hepatocellular degeneration, and appearance of multinucleated giant cells; may be difficult to distinguish from biliary atresia, but is more likely to end with recovery, although cirrhosis may develop.A nonspecific reaction of the newborn liver to increased conjugated hyperbilirubinemia, which occurs with intra- or extrahepatic biliary atresia, erythroblastosis fetalis, TORCH (toxoplasmosis, rubella, cytomegalovirus, herpes simplex) and other in utero and neonatal infections (e.g., coxsackie, hepatitis, Escherichia coli infection, syphilis) and metabolic defects (e.g., a1-antitrypsin deficiency; cystic fibrosis; hereditary fructose intolerance; galactosemia; tyrosinosis requiring parenteral nutrition; choledocal cysts, idiopathic, congenital hepatic fibrosis, trisomy 18 and Byler’s, Lucey-Driscoll, Niemann-Pick and Zellweger’s diseases)
