title: [A case of prostatic cystadenoma].
abstract: 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.
