Giant renal metastasis from prostate cancer mimicking renal cell carcinoma

Özet

The most common sites for prostate cancer metastasis include bone, distant lymph nodes, liver and lungs.Renal metastasis of prostate cancer is a rarely seen pattern of invasion. In the current study, we described an83-year-old male with a history of prostate cancer. He was admitted because of edema, hyperemia, warm andpain at left leg and inguinal region. In the further evaluation, a mass lesion at prostate region and conglomeratelymphadenopathy at left iliac vascular trajectory and a mass lesion at left kidney with heterogeneouscontrast-enhancement were observed on contrast-enhanced magnetic resonance imaging and computerizedtomography scan. Fine-needle aspiration biopsy was performed in the lesion with radiologically suspect renalcell carcinoma. By evaluating histopathological features and immunohistochemical staining of the tumor, wedecided that the lesion was metastasis from prostate cancer.
