Mediastinum and retroperitoneum are exceedingly rare sites for metastatic prostate cancer to occur. Here, we present the case of a 67-year-old male patient with incidental findings of mediastinal and retroperitoneal masses which were found to be due to metastatic prostate adenocarcinoma based on histopathology and immunohistochemical studies and later on supported by the significantly elevated Prostate Specific Antigen (PSA) levels. Prostate cancer should always be considered in the differential diagnosis of elderly men presenting with metastatic epithelial tumors even in unusual sites.
纵隔和腹膜后是转移性前列腺癌极为罕见的发生部位。在此,我们报告一例67岁男性患者,偶然发现纵隔和腹膜后肿块,经组织病理学和免疫组化研究发现是转移性前列腺腺癌所致,随后前列腺特异性抗原(PSA)水平显著升高进一步支持了这一诊断。对于出现转移性上皮肿瘤的老年男性,即使肿瘤位于不常见部位,在鉴别诊断时也应始终考虑前列腺癌。
