Unusual ultrasound presentation of testicular metastasis from renal clear cell carcinoma

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.
