These sections through a prostate removed via radical prostatectomy reveal irregular yellowish nodules, mostly in the posterior portion (seen here superiorly). This proved to be prostatic adenocarcinoma. Prostate glands containing adenocarcinoma are not necessarily enlarged. Adenocarcinoma may also coexist with hyperplasia. However, prostatic hyperplasia is not a premalignant lesion. Staging of prostatic adenocarcinoma is based upon how extensive the tumor is.

At the right are normal prostatic glands containing scattered corpora amylacea. At the left is prostatic adenocarcinoma. Note how the glands of the carcinoma are small and crowded. Prostatic adenocarcinomas are given a histologic grade.
