Abstract

Isolated anterior urethral metastases from prostate cancer are rare. The pathogenesis of this form of loco-regional recurrence may be related to spread by instrumentation-induced implantation and could potentially then be associated with a better prognosis than metastatic disease secondary to a more malignant phenotype. We report a case of a 68-year-old man with high-risk prostate cancer, diagnosed at transurethral resection of prostate, who was originally treated with combination external beam radiotherapy and hormonal therapy. He re-presented 4 years after his original diagnosis with recurrent gross hematuria and cystourethroscopic biopsies of anterior urethral polyps revealing isolated recurrent prostatic adenocarcinoma. We present our this case and review the literature.
