Carcinosarcoma of native renal pelvis in recipient after a renal transplant: a case report.

BACKGROUND

Carcinosarcoma is a malignancy that rarely occurs in the renal pelvis.

MATERIALS AND

METHODS

We present a case of histologically proven, native renal pelvis carcinosarcoma in a 65-year-old woman who had accepted a renal transplant. We performed a laparoscopic ureterectomy, combined with lymph node dissection and immunosuppression with sirolimus (SRL), which was alternated with the conventional immunosuppressant--cyclosporine.

RESULTS

This patient was still alive 34 months after renal transplantation.

CONCLUSIONS

Operation is still the best choice, and the SRL may be beneficial for preventing the progression of a tumor.
