Objective: To investigate the architectural features and frequency of glomeruloid features in pathological section of prostatic adenocarcinoma and evaluate the association between glomerulations and its clinical data.
Methods: We studied 196 prostatic adenocarcinoma specimens obtained from needle biopsies or radical prostatectomy and their clinical data, and reviewed related literatures.
Results: Three of the 196 cases showed glomeruloid features, the Gleason score of which was 7, 8, and 8, respectively. Of the 3 cases 1 had osseous metastasis and 2 extraprostatic nervus extension. After 5 to 15 months' follow-up, 1 case died and the other 2 still under treatment.
Conclusion: Glomeruloid structures in the prostate represented an uncommon but distinctive growth pattern that was specific for malignancy. Glomeruloid structures were usually seen in high-grade adenocarcinoma, often with extraprostatic extension.
