[Prostatic adenocarcinoma with glomeruloid structure].

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.
