Radical prostatectomy for high grade prostatic intraepithelial neoplasia.

High Grade Prostatic Intraepithelial Neoplasia (HGPIN) has been recognized as the most likely precursor of invasive carcinoma of the prostate. Close surveillance and follow-up are indicated if subsequent procedures fail to identify carcinoma. There is still considerable controversy about the natural history of high grade PIN and most authors agree that its identification should not influence or dictate therapeutic decisions. We performed a prophylactic radical prostatectomy in such a case which has not been reported in the world literature.
