Prostate cambial (stem)-zone and microcarcinoma: immunohistochemical and morphometric study approach

Area of Science:

• Urological pathology
• Prostate cancer research
• Histopathology

Background:

• Distinguishing atypical hyperplasia from benign prostatic hyperplasia and prostate cancer is clinically significant.
• Accurate diagnosis relies on detailed histological examination.

Purpose of the Study:

• To identify key histological and morphometric criteria for differentiating atypical hyperplasia (cambial zone) from benign prostatic hyperplasia, microcarcinoma, and other prostate cancers.
• To evaluate the utility of keratin expression and nuclear morphology in differential diagnosis.

Main Methods:

• Comparative histological, immunohistochemical, and morphometric analysis of 30 surgically removed prostate specimens.
• Assessment of keratin presence/absence and mean nuclear area of nuclear profiles.

Main Results:

• Keratin presence and mean nuclear area were identified as crucial differential criteria.
• These parameters effectively distinguish atypical hyperplasia (cambial zone) from benign prostatic hyperplasia and various prostate cancers.

Conclusions:

• Histological and morphometric features, specifically keratin expression and nuclear size, are reliable indicators for differentiating prostate pathologies.
• This study provides valuable criteria for accurate diagnosis in surgical pathology of the prostate.
