A neonate presents with jaundice and clay coloured stools. Liver biopsy shows giant cells diagnosis is –
Neonatal hepatitis with physiological jaundice
Neonatal hepatitis with extrahepatic biliary atresia
Physiological jaundice
Physiological jaundice with extrahepatic biliary atresia
Jaundice with clay coloured stools suggests cholestasis.
Both neonatal hepatitis and extrahepatic biliary atresia cause cholestasis jaundice.
"Giant cells" are characteristics of both neonatal hepatitis and Extrahepatic Biliary Atresia.
Therefore the answer is Neonatal hepatitis with extrahepatic Biliary Atresia.
Idiopathic neonatal hepatitis
It is also referred to as giant cell hepatitis.
This type of cholestatic jaundice of unknown cause presents with features of cholestasis and a typical liver biopsy appearance.
It is characterized by -

i) Obstructive jaundice (cholestasis) ii) Giant cell transformation in liver                 Ili) Patent bile ducts

Presenting features are suggestive of intrahepatic cholestasis -


Acholic stools                          o Emesis                                o IUGR


Poor feeding                            o Prematurity                       o Poor growth
