右侧是正常前列腺，可见散在分布的淀粉样小体；左侧是前列腺癌，可见癌腺体小而拥挤。前列腺癌的组织学分级（如Gleason氏分级系统最常使用）。例如，此腺癌的Gleason分级为3/3。
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 (Gleason's grading system is used most often, and includes a score of 1 to 5 for the most prominent component added to a score of 1 to 5 for the next most common pattern). For example, this adenocarcinoma could be given a Gleason of 3/3.
