Abstract: Prostate cancer with metastasis to the kidney is rare. Here, we report a case of prostate cancer metastasizing to renal cell carcinoma. A 67-year-old male presented with low back pain for 3 months, aggravated with persistent fever for 2 weeks in June 2018.Histopathological diagnosis of prostate adenocarcinoma was established. Meanwhile, contrasted CT of the abdomen showed a 3.0 cm×2.5 cm×2.5 cm enhanced solid mass on the lower pole of the right kidney. Nephron-sparing surgery was performed for the renal mass. Histopathology revealed a Grade 2 renal clear cell carcinoma with focal prostate carcinoma metastasis to the tumor. Then the patient received abiraterone acetate (AA) therapy. The patient did not encounter tumor recurrence in right kidney 18 months after surgery. However, PSA progression occurred 6 months later after AA therapy, then docetaxel chemotherapy and Sr 89 therapy were performed with limited efficacy. The patient died after 30 months.
