Two patients with disseminated prostatic cancer underwent transrectal ultrasonographic examination. In the rectal wall, at the prostatic level, tumor infiltration was seen without obvious communication to the prostate. Biopsy demonstrated adenocarcinoma, and immunohistochemic staining for prostatic specific antigen (PSA) was positive. We recommend the application of PSA staining in biopsy specimens of unclear rectal masses.
两名患有播散性前列腺癌的患者接受了经直肠超声检查。在直肠壁前列腺水平处，可见肿瘤浸润，且与前列腺无明显连通。活检显示为腺癌，前列腺特异性抗原（PSA）免疫组化染色呈阳性。我们建议对不明直肠肿块的活检标本应用PSA染色。
