A 64-year-old man with a 4-month history of dysuria and urinary frequency had a mass behind the bladder. The preoperative diagnosis was a tumor of the left seminal vesicle, but a histologic examination revealed benign prostatic tissue. This is the seventh reported case of ectopic prostatic tissue situated outside the urinary tract.
