We report a case of prostatic cystadenoma in a 45-year-old man with the complaint of urinary retention. The large mass was palpated on rectal examination. The tumor was localized in the position of the left lobe of the prostate and was seen as multi-ocular on computerized tomographic (CT) scan. The serum levels of prostatic acid phosphatase (PAP) and prostate specific antigen (PSA) were slightly elevated. The tumor was enucleated retropubically, it weighed 210 g and had an multilocular structure macroscopically. The cyst seen on microscopic examination was lined with cuboidal or columnar epithelial cells and the lining cells were focally multilayered and formed papillary projections. The stroma surrounding the glands was composed of fibrous tissue containing smooth muscle fibers. The epithelial cells were immunoreactive for PAP and PSA.
我们报告一例45岁男性前列腺囊腺瘤病例，该患者因尿潴留前来就诊。直肠指检可触及一巨大肿块。肿瘤位于前列腺左叶位置，计算机断层扫描（CT）显示为多房性。前列腺酸性磷酸酶（PAP）和前列腺特异性抗原（PSA）血清水平略有升高。经耻骨后肿瘤剜除术，肿瘤重210 g，肉眼可见多房结构。显微镜检查可见囊肿内衬立方形或柱状上皮细胞，内衬细胞局灶性多层排列并形成乳头状突起。腺体周围的间质由含有平滑肌纤维的纤维组织组成。上皮细胞对PAP和PSA呈免疫反应阳性。
