[Ectopic prostatic tissue in the bladder].

Abstract

We report the case of a 58-year-old man with ectopic prostatic tissue at the bladder trigone. The diagnosis was by chance during study and treatment of benign prostatic hyperplasia. The appearance was pseudocystic. It occupied completely the bladder trigone. On histology, the lesion was formed by prostatic type-glands, which were positive for the presence of prostatic specific antigen by using inmunoperoxidase technique. It was partially covered by normal urothelium. Ten months later, no trace of recurrence has been evidenced.
