Abstract:
To histologically compare benign prostatic hyperplasia with proslalic adenocarcinoma, a morphometric study was conducted on 20 cases of benign prostatic hyperplasia and 16 cases of prostatic adenocarcinoma. Adenocarcinoma group was divided into two subgroups. well differentiated (9 cases) and poorly differentiated (7 cases), based on the Gleason grading system. By means of computerized image analyzer, about 30 to 40 cells for each case were examined to evaluate mean nuclear area and perimeter, mean standard deviations and mean form factor. Mean form factor, the most prominent parameter in our study, was significantly different among BPH (1.063+/-0.008), well differentiated adenocarcinoma (1.089+/-0.018) and poorly differentiated adenocarcinoma (1.135 +/-0.057 ). Mean standard deviations of mean nuclear area and perimeter were significantly different between benign prostatic hyperplasia and well differentiated prostatic adenocarcinoma. .Morphometry. may provide the pathologists with a helpful technique, allowing them to analyze pathological material accurately. and in a more quantitative and reproducible fashion.
