Acute Rejection Grading

Figure 1. In this example of moderate acute rejection, most of the portal triads are expanded by a rejection infiltrate. In the Banff Schema, this biopsy would receive a score of "2" or moderate portal inflammation. However, perivenular inflammation associated with centrilobular hepatocyte necrosis is not seen.

Please mail comments, corrections or suggestions to the TPIS administration at the UPMC.
