Figure 3. PTLD involvement of allograft kidney. PTLD is often extranodal and frequently involves the allgoraft itself. In the case of renal transplant recipients, allograft involvement is seen in about 1/3 of cases. Such involvement may develop as an infiltrative process or it may form one or more tumors.The tumor presents in this case as a yellow mass which projects from the surface of the kidney.

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