Prostate cancer metastasis mimicking a primary urothelial carcinoma of the bladder

Abstract

Abstract We report on a 79-year-old male patient who presented with asymptomatic elevation of prostate-specific antigen and a concurrent papillary lesion, which raised the suspicion of synchronous bladder and prostatic malignancies. He underwent a trans-perineal prostate biopsy as well as transurethral resection of bladder tumour, which revealed a Gleason 9 adenocarcinoma of prostatic origin. While synchronous bladder and prostate cancer is a possibility, differential diagnosis in a patient presenting with lesions of the bladder neck should include advanced prostate cancer.
