Ten cases of prostatic epithelial polyps of the prostatic urethra are reported. The ages of the patients were from 27 to 69 years, with a mean of 44 years. The most common clinical signs were gross hematuria, microhematuria, hematospermia, and dysuria. All specimens, obtained by transurethral resection, had a papillary or polypoid configuration. The tissue had a glandular structure that resembled that of the prostate. Prostate-specific antigen and prostatic acid phosphatase were found in the epithelial cells of the polyps by indirect immunoperoxidase staining. The polyps seemed to be hyperplasia of prostate-specific antigen and prostatic acid phosphatase-positive epithelial cells of the prostatic gland or duct, especially that of the latter.
报告了10例前列腺尿道部的前列腺上皮息肉。患者年龄在27至69岁之间，平均年龄为44岁。最常见的临床症状是肉眼血尿、镜下血尿、血精和排尿困难。所有经尿道切除术获取的标本均呈乳头状或息肉状结构。组织具有类似于前列腺的腺管结构。通过间接免疫过氧化物酶染色在息肉的上皮细胞中发现了前列腺特异性抗原和前列腺酸性磷酸酶。这些息肉似乎是前列腺腺管或导管中前列腺特异性抗原和前列腺酸性磷酸酶阳性上皮细胞的增生，尤其是后者。
