[Testicular metastasis and local recurrence of renal cell carcinoma after nephron-sparing surgery in von Hippel-Lindau disease].

Bilateral nephron-sparing surgery was performed on a 56-year-old man with von Hippel-Lindau disease as initial therapy for renal cell carcinoma (RCC). Two years after the surgery, an abdominal computerized tomography (CT) scan revealed local recurrence of RCC. The patient was admitted to our hospital after another CT scan three years later that indicated aggravation of the cancer. On physical examination, he complained of swelling of the scrotum. The patient was diagnosed with an intra-scrotal malignant tumor and local recurrence of RCC. We performed high orchiectomy and nephrectomy. The testicular tumor was diagnosed as testicular metastasis of RCC on pathological examination.
