A 25 year old man male presented with a lump in the left side of the abdomen. Ultrasonography revealed an echogenic retroperitoneal mass with hyperechoic areas within it suggestive of bone. CT scan confirmed the presence of a large retroperitoneal mass with bone within it. On exploration there was a large encapsulated retroperitoneal lump. There was a soft tissue mass within the lump surrounded by a yellow pultaceous material admixed with pus. Examination of the specimen showed a bone at the cephalic end with teeth embedded within it. There were two limb buds near the cephalic end. The whole specimen was covered with skin with all its appendages. There was coelomic cavity present. The distinction between fetus in fetus and teratoma has for long been the subject of controversy. According to the criteria described by Willis, there should be a vertebral axis present to make the diagnosis of fetus in fetu. But there have been a few reports where cases have been described as fetus in fetu even in the absence of a vertebral axis. A review of the literature concerning this controversy is briefly given.
一名25岁男性因左侧腹部肿块就诊。超声检查发现腹膜后有一回声增强的肿块，内部有高回声区，提示有骨质。CT扫描证实存在一个大的腹膜后肿块，内部有骨质。手术探查发现一个大的有包膜的腹膜后肿块。肿块内有一个软组织肿块，周围是黄色脓性物质并混有脓液。标本检查显示，肿块头部有一块骨头，上面嵌有牙齿。在头部附近有两个肢体芽。整个标本覆盖着皮肤及其所有附属结构。存在体腔。胎中胎与畸胎瘤的鉴别长期以来一直是争议的话题。根据威利斯描述的标准，诊断胎中胎应存在脊椎轴。但也有一些报道称，即使没有脊椎轴，病例也被描述为胎中胎。本文简要回顾了有关这一争议的文献。
