Prostate cancer is one of the leading cancers affecting men worldwide. Only 4% of prostate cancer patients will develop secondary metastases to the testis. The prognosis is poor, and their appearance is often a sign of advanced disease. We present the case of a male patient with metastatic prostate cancer. Testicular metastasis was identified during his oncologic follow-up; the pathology report revealed poorly differentiated adenocarcinoma metastasis. The patient’s functional status progressively deteriorated and he died from causes related to his cancer despite multiple lines of treatment. Although there are common sites of recurrence, metastases can occur in uncommon locations, including the testis; any evidence of distant disease should be investigated.
