Abstract:

The immunohistochemical method was used to show the human chorionic gonadotropin (hCG)and human placental lactogen(hPL) positive cells in uterine myoma,endometrium,decidua and chorion of early human pregnancy,and to study the differentiation and clinical application of these cells.There were four kinds of hCG and hPL positive cells in decidua of early human pregnancy.Because it is difficult to identify them by HE staining,this study will provide a new way in the diagnosis of exrtauterine pregnancy and early uterine pregnancy.Furthermore,there is another kind of cells which is positive to hPL and negtive to hCG.It is proposed that these cells come from the cytotrophoblastic cells after moving into the endometrium.They may be of great value in the study of the chorionepithelioma.

Key words: uterine myoma, endometrium, hCG, hPL, immunohistochemistry
