Acute Rejection Grading

In this more intense example of moderate acute rejection, the crypts are widely separated by an extensive inflammatory infiltrate filling lamina propria. The specimen is not optimally oriented, and the villous architecture is therefore difficult to assess. Nonetheless the surface epithelium is present and there is no luminal exudate to suggest mucosal erosion.

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