Pathology of carcinoma of the prostate.

In this presentation the authors review the pathology of prostatic carcinoma (PCa), and discuss criteria for pathologic diagnosis, premalignant lesions, lesions that simulate PCa, immunopathology, special types of PCa, effects of therapy on the prostate, and recent efforts to improve diagnostic and prognostic capabilities. The possible role of study of nucleolar organizing regions is reported. A new method for demonstration of chromosome in formalin-fixed, paraffin-embedded tissue is presented. The need for research in all aspects of pathology is emphasized.
