Living-donor transplantation after excision of unrecognized renal cancer diagnosed after transplant.

Background: Published data on kidneys transplanted after resecting small renal cancers during the transplantation surgery are very rare and, to the best of our knowledge, no pediatric cases have been reported in the literature.

Case-diagnosis/treatment: Our patient was diagnosed with a bilateral Wilms tumor when he was 15 months old. A total bilateral nephrectomy was required to control the disease.
