Introduction
The occurrence of secondary malignant neoplasm (SMN) in association with chemoradiotherapy for nephroblastoma is well-established; however, the incidence of secondary RCC is relatively uncommon.1Furthermore, only a limited number of case reports have detailed the development of translocation RCC following nephroblastoma treatment. In this study, we present a rare case of secondary RCC following open nephrectomy and postoperative chemoradiotherapy for nephroblastoma.
