BACKGROUND
The diseases that cause neonatal cholestasis display several overlapping clinical feature. Making the differential diagnosis using liver biopsy specimens from infants with neonatal cholestasis is important for delivering the proper treatment.
METHODS
We assessed the clinical manifestations, laboratory data, and histopathologic features of the pretreatment liver biopsy specimens from patients suffering with biliary atresia (n=66), intrahepatic bile duct paucity (n=15), and neonatal hepatitis (n=21).
RESULTS
The gender distribution was nearly equal for the patients with biliary atresia and intrahepatic bile duct paucity, whereas males predominated for the cases of neonatal hepatitis. Only the gamma-glutamyl transferase level differed significantly amongst the groups. The diagnostic features for making the differential diagnosis of bile duct lesions included marked bile ductular proliferation, severe fibrosis, and bile duct loss. The difference of the average percentage of portal tracts with bile duct loss was statistically significant between the patients with intrahepatic bile duct paucity (73.9%) and those patients with neonatal hepatitis (39.1%) (p<0.001).
CONCLUSIONS
Bile ductular proliferation, bile duct loss, and advanced fibrosis are useful for the differential diagnosis of neonatal cholestasis. Moreover, stricter diagnostic criteria for bile duct loss (more than 2/3 of bile ducts) should be applied for the definitive diagnosis of intrahepatic bile duct paucity, because bile duct loss also frequently occurs in infants suffering with neonatal hepatitis.

Abstract PDF: BACKGROUND
Idiopathic portal hypertension (IPH) is a rare clinicopathologic entity that shows clinical evidences of portal hypertension with no pathologic features of cirrhosis.
METHODS
The clinical and pathologic features of 8 cases with IPH were analyzed via the medical records along with the biopsy or resected liver specimens.
RESULTS
Six patients were male and two were female. The chief complaints were sudden variceal bleeding in seven patients and abdominal pain in one patient. Six patients were treated with varix ligation and one was treated with splenectomy after the failure of bleeding control. One patient underwent a liver transplantation due to severe symptoms of portal hypertension. The prognosis of all the patients was excellent. Microscopically, the portal tracts were variably fibrotic, and the portal veins in them were sclerotic, obliterated or dilated in 7 cases; pathologic abnormalities were absent in 1 case. Cirrhosis was absent in all cases, while septal fibrosis was present in one resected liver.
CONCLUSIONS
IPH is a minor cause of portal hypertension. However, a liver biopsy to show the subtle portal vascular changes and fibrosis in patients who have the clinical symptoms of portal hypertension is important for making the diagnosis of IPH.

Abstract PDF: Posttransplant lymphoproliferative disorder (PTLD) is a proliferation of B-cells associated with Epstein-Barr virus (EBV) infection as a complication of immunosuppression, especially by FK506. We investigated four cases of PTLD which developed either in allografts or in other organs.
Case
1 was a 38-year-old woman, who developed monomorphic PTLD in a kidney 7 years and 7 months after renal transplantation. Case 2 was a 37-year-old man, who developed monomorphic PTLD in the right submandibular lymph node 4 months after liver transplantation. Case 3 was a 60-year-old man, who developed monomorphic PTLD in the liver 8 months after liver transplantation. Case 4 was a 2-year-old female child, who developed polymorphic PTLD in the colon, liver, and mesenteric lymph node 10 months after liver transplantation. FK506 was administered to case 4. EBV was identified in the tissues of all cases by immunohistochemistry and/or in situ hybridization.
