Adenosis difusa de la zona periférica de la próstata

We present two cases of DAPZ. Although needle core biopsies had some areas resembling adenocarcinoma, immunostaining demonstrated the presence of basal cells in glands showing a pseudoinfiltrative pattern. It must be emphasized that prostatic peripheral zone diffuse adenosis is a risk factor for adenocarcinoma and that in nearly 50% of cases adenocarcinoma will be found in subsequent biopsies.
