1.   Sections of formalin fixed native livers and liver allograft biopsy specimens were routinely stained with haematoxylin and eosin, trichrome, and periodic acid Schiff with diastase.

2.   Progressive disease was more common in older recipients and along patients with active inflammation and HBcAg in their native livers.

3.   Progressive disease did not occur in the infected allograft when the corresponding native livers showed quiescent cirrhosis or massive necrosis.

4.   In one patient, the diagnosis of sclerosing cholangitis became apparent only after examination of the native liver after hepatic transplantation.
