An 80-year-old man was admitted to our hospital with the chief complaint of urinary retention. On physical examination, a large tumor was recognized in pelvic cavity. Serum levels of prostatic acid phosphatase and gamma-seminoprotein were elevated. Anterior pelvic exenteration was performed because the tumor was huge and malignancy could not be ruled out preoperatively. The tumor weight was 660 g (11 x 8 x 7 cm) and had a multicystic structure macroscopically. Immunohistochemical study by the prostatic specific antigen stain showed positive staining in the epithelial cells of the tumor, which suggest that the tumor was of prostatic origin.
一名80岁男性因尿潴留为主诉入院。体格检查时，在盆腔发现一个大肿瘤。血清前列腺酸性磷酸酶和γ-精浆蛋白水平升高。由于肿瘤巨大且术前不能排除恶性，故行前盆腔脏器清除术。肿瘤重660克（11×8×7厘米），肉眼可见多囊结构。前列腺特异性抗原染色的免疫组织化学研究显示肿瘤上皮细胞呈阳性染色，提示肿瘤起源于前列腺。
