This report reviews proliferative diseases of intermediate trophoblast cells and summarises clinical findings and pathohistological and immunohistochemical features of a placental site nodule. This recently described entity is an endometrial or endocervical benign proliferation of intermediate trophoblast cells occurring after intrauterine gestation. Patients usually present with a history of abnormal vaginal bleeding and frequently cells that are present in their cervical smears are misinterpreted as squamous dysplasia. In such cases it is important to distinguish the placental site nodule from squamous lesions or decidual polyps; this is possible by means of immunohistochemistry.
本报告回顾了中间型滋养层细胞增殖性疾病，并总结了胎盘部位结节的临床发现、病理组织学及免疫组化特征。这种最近才被描述的病变是一种发生于宫内妊娠后的子宫内膜或宫颈内膜中间型滋养层细胞的良性增殖。患者通常有异常阴道出血病史，其宫颈涂片内的细胞常被误诊为鳞状上皮发育异常。在此类病例中，将胎盘部位结节与鳞状病变或蜕膜息肉区分开来很重要；借助免疫组化即可做到这一点。
