[Prostate cancer after subcapsular prostatectomy diagnosed as benign prostate hypertrophy--clinico-pathological analysis].

Of 160 newly diagnosed cases of prostate cancer during last 11 years, six (3.75%) had a prior subcapsular prostatectomy. Digital rectal examination in these six cases revealed a significant prostatic abnormality and multiple bone metastases were showed. Histological examination by step-section technique was done retrospectively using surgical materials from subcapsular prostatectomy. Two cases of incidental carcinoma were detected histologically. One showed stage A1 and another stage A2. Continuous observation should be performed after prostatectomy, even if the surgical specimens revealed no carcinoma.
