[Neonatal cholestasis: the viewpoint of the pathologist].

The authors make a review of paediatric-neonatal cholestasis, a troublesome field in clinical and hepatopathology. They focus the main topics and stress the differential aspects in extrahepatic biliary atresia, "neonatal hepatitis", cholestatic syndromes associated with paucity of interlobular biliary ducts and metabolic diseases. The "overlap" areas and differential diagnosis in these chapters are a challenge for the pathologist. The importance of a close collaboration with clinicians is stressed.
