A series of 25 prostate glands removed by radical perineal prostatectomy because of clinically evident carcinoma was examined by means of multiple whole‐gland sections to delineate localization of tumor in relation to intact anatomical landmarks. Multiple foci of tumor origin were found in 6 prostate glands (24%)—2 foci in 4 cases and 3 foci in 2 cases. Various definitions of the “posterior lobe” have given rise to confusion and disagreement regarding sites of origin of carcinoma within the prostate gland; in the present series there was no evident predilection for origin of carcinoma in the anatomic posterior lobe. The peripheral or subcapsular region of the prostate gland was the common site of origin in contrast to the periurethral region. Lymphatic invasion was present in 31 of the 33 carcinomas (94%).
