   Abstract 

Renal cell carcinoma (RCC) of the transplanted kidney is rare. In Iran, until 2004, 15000 kidney transplantations were performed, mostly from living donors. We report the first case of renal cell carcinoma in transplanted kidney, four years after transplantation, which was treated with nephron sparing or partial nephrectomy.

   Introduction Top


Cancer is more common in transplant reci­pients than in the general population. However, renal cell carcinoma (RCC) of the transplanted kidney is rare. [1],[2],[3] In Iran, until 2004, 15000 kidney transplantations were performed, mostly from living donors. We report the first case of renal cell carcinoma developing in a trans­planted kidney, four years after transplantation, which was treated with nephron sparing.


   Case Report Top


A 49-year-old woman with glomerulopathy that progressed to end-stage renal disease underwent preemptive renal transplantation from unrelated living donor in October 1999. Post transplantation, the function of the transplanted kidney was normal with serum creatinine ranging from 0.7 to 1.4 mg/dl (79 to 158 µmol/L). Immunosupression con­sisted of 10 mg prednisolone once daily, 100 mg cyclosporine twice daily and 100 mg azathioprine once daily. In December 2003, the patient developed microscopic hematuria that was detected by a routine urinalysis with­out any pain or discomfort. The ultrasound of the transplanted kidney detected a 4-4.5 centimeters (cm) solid mass at the lower pole of the kidney, [Figure - 1]. Computerized tomography (CT) scan and magnetic resonance tomography (MRI) confirmed the ultrasound findings, [Figure - 2]. Needle aspiration of the solid mass was performed under sonography control but pathological report was unspecific because the mass was solid and the hematuria conti­nued. The mass was resected with a one centimeter margin of apparently normal tissue. The microscopic examination revealed a poorly differentiated RCC, but the margins were not involved. At two weeks after operation, creatinine was 0.7 mg/dl. Blood biochemical examination, monthly sonography and urin­alysis were normal, [Figure - 3].


   Discussion Top


The indication for nephron sparing includes bilateral renal cell carcinoma and renal cell carcinoma in a solitary kidney. [4],[5],[6] It is an effective treatment for single localized tumors less than 4 cm. Regular sonography of the transplanted kidney every 3-6 months may detect the development of tumor at early stage, when it is less than 4 cm. Accordingly, we may be able to save the transplanted kidney with nephron sparing or partial nephrectomy and keep its function normal. Moreover, it is necessary to reduce the amount of immuno­suppression after resection of the tumor. [7],[8],[9]

Thus we believe that routine sonography may detect tumors in the transplanted kidney of less than 4 cm and enables treatment with nephron sparing or partial nephrectomy without the need for radical nephrectomy.
