[A case of giant transitional cell carcinoma of the prostate].

A 69-year-old man presented with a complaint of pollakisuria, dysuria and anal pain. Digital rectal examination, transrectal ultrasonography and tumor marker of the prostate indicated a giant benign prostate hypertrophy (BPH), but urethrocystogram and magnetic resonance imaging (MRI) of the prostate was not typical of BPH. A diagnosis of giant BPH was made by transrectal needle biopsy of the prostate. However, symptoms of dysuria and anal pain became severe and then a catheter was indwelt into his bladder. A biopsy performed, 3 months later revealed transitional cell carcinoma in the specimens, but he suddenly died of pulmonary infarction.
