Abstract Specimens from 30 cases of benign prostatichyperplasia and 75 cases of prostatic carcinomaobtained during suprapubic prostatectomy, transurethalresection of the prostate and radical prostatectomy,were stained immunohistochemically for S-100 protein,prostatic acid phosphatase (PAP), prostatic specificantigen (PSA), neuron specific enolase (NSE) andpolyclonal keratin. S-100 protein was positive in9.3% of prostatic carcinomas and negative in allcases of prostatic hyperplasia. PAP and PSA werepositive in all cases, while NSE was positive in 16%of the carcinoma cases. Polyclonal keratin waspositive in both cell layers of the double layeredhyperplastic prostatic epithelium with a more intensestaining pattern in the outer cell layer. The authorsbelieve that the S-100 protein immunoreactivityobserved in some prostatic carcinomas, reflecting thechange in the functional status of the neoplasticcells, might be of prognostic significance. They alsoemphasize the non-myoepithelial nature of the outercell layer of the double layered prostaticepithelium.
