title: Unusual Ultrasound Presentation of Testicular Metastasis from Renal Clear Cell Carcinoma.
abstract: Testicular metastases from renal clear cell carcinoma (RCC) are extremely uncommon. To the best of our knowledge, only 32 cases have been reported in the literature. We report a rare case of testicular metastasis from RCC. A 69-year-old patient presented with discomfort and pain in his left testis. He had undergone laparoscopic left radical nephrectomy at another institution. Scrotal ultrasonography revealed a non-palpable lesion at the upper pole of the left testis with hypoechoic aspect, highly suspicious for malignancy. We performed a left inguinal orchiectomy. The testicular lesion was diagnosed as a metastasis from RCC. After orchiectomy, a computed tomography of the chest and abdomen revealed no other metastatic lesions. The patient remains free of clinical recurrence after 20 months without adjuvant therapy.
