This case report is of a benign retroperitoneal teratoma which was adherent to the psoas muscle of a 53-year-old female cadaver with a history of metastatic bladder cancer as a cause of death. Teratomas possess derivatives of all three germ cell layers and are usually seen either in children or in the lower pelvic region of adults. The finding of this mass deep to the inferior pole of the kidney is quite unusual. Few studies mention a possible association between metastatic cancer and teratoma growth in extrapelvic locations. The following report is a detailed account of this unusual finding and a summary of the literature on growths of this kind.
本病例报告介绍了一例良性腹膜后畸胎瘤，该肿瘤附着于一名 53 岁女性尸体的腰大肌上，该女性因膀胱癌转移而死亡。畸胎瘤具有三个胚层的衍生物，通常见于儿童或成人的下骨盆区域。在肾脏下极深部发现这种肿块是非常罕见的。很少有研究提到转移性癌症与盆腔外部位的畸胎瘤生长之间可能存在关联。以下报告详细介绍了这一不寻常的发现，并对这类生长物的文献进行了总结。
