Conclusion
We report a case of contralateral translocation RCC after treatment of nephroblastoma with radical resection by partial nephrectomy. RCC is a rare SMN following nephroblastoma treatment, with only two reported cases of translocation RCC. This case implies that the prospect of translocation RCC should be considered as a secondary renal neoplasm post-chemoradiotherapy. Moreover, if the case is operable, partial nephrectomy can be considered for functional and oncological outcomes.
