Bilateral testicular metastases from prostatic carcinoma.

Testicular metastasis from carcinoma of the prostate is rare. We report a case of carcinoma of the prostate with bilateral testicular metastases 7 years after the initial diagnosis. The exact prognosis is not known but it usually indicates advanced disease. Although testicular metastasis is uncommon, it should be considered when a patient presents with a lump in the testis, particularly in a patient known to have another primary malignancy.
