Simultaneous Bilateral Testicular Metastases from Renal Clear Cell Carcinoma: A Rare Presentation in Von Hippel-Lindau disease.

In this article, we present a Von Hippel-Lindau (VHL) patient with synchoronus bilateral testicular metastasis from renal cell carcinoma (RCC). A 50 year-old man, a known case of VHL syndrome was referred with palpable masses in both the testes. His medical history demonstrated that he had undergone the brain surgery for cerebellar hemangioblastoma. He had undergone simultaneous Whipple's pancreatectomy and left radical nephrectomy becuase of well-differentiated neuroendocrine tumors in head and body of the pancreas and a 6-cm clear cell-type grade-3 RCC in the left kidney. Scrotal sonography demonstrated vascular and heteroechogen masses measuring 19×14 mm in lower pole of the right testicle, 19×16 mm in upper pole of the right testicle, and 23×16.5 mm in upper pole of the left testicle. After having patient's consent, bilateral orchiectomy was performed by inguinal incision. Histopathologic examination and immunohistochemistry staining revealed metastasis from RCC. The most common neoplasm of reproductive system in VHL patients is epididymal papillary cystadenoma. Owing to it's benign nature, the management is conservative with routine physical examination and ultrasonography. Our patient indicated that every scrotal mass in patients with VHL is not to be considered as epididymal papillary cystadenoma.
