De novo papillary carcinoma in a renal allograft: the pros and cons of immunosuppression.

We present a case of a multifocal kidney transplant renal cell carcinoma in a 35-year-old lady, presenting 16 years after kidney transplantation, diagnosed during investigation of recurrent urinary tract infections. The patient underwent a graft nephrectomy and subsequently maintained on haemodialysis. She remained disease-free after 4 years of surveillance and thus reactivated on the transplant list. This case reinforces the fact that immunosuppressive therapy has made kidney transplantation possible; however, it is accompanied by a higher incidence of malignancy. It also reinforces the importance of lifelong screening of both native and renal transplant grafts.
