An immunohistochemical study on the tissue localization of human chorionic
gonadotropin (HCG), human placental lactogen (HPL), and human pregnancy specific
beta-1 glycoprotein (SP-1) in the non-neoplastic (5 incomplete abortion, 5 ectopic
pregnancy) and neoplastic (hydatidiform mole 3 cases, 5 ectopic pregnancy) and
neoplastic (hydatidiform mole 3 cases, choriocarcinoma 2 cases) gestational status, and
germ cell tumors of the ovary (dysgerminoma 2 cases, immature teratoma 1 case) and
the testis (seminoma 2 cases, endodermal sinus tumor 1 case) by means of sensitize
peroxidase-antiperoxidase method.
The results were as follows.
1 ) Cytoplasmic HCG, HPL, and SP-1 were readily identified in syncytiotrophoblasts
of chorionic villi of the incomplete Abortion and ectopic pregnancy, as moderate to
strong positive reactions. In the cytoplasm of the neoplastic syncytiotrophoblasts of
hydatidiform mole and choriocarcinoma, positive reactions were stronger than in
non-neoplastic syncytiotrophoblasts. But the cytotrophoblasts and villous stromal cells
showed negative reactions to these hormones.
2) All of the tumor cells of dysgerminoma and immature teratoma of the ovary, and
seminoma and endodermal sinus tumor of the testis showed negative reactions to HCG,
HPL, and SP-1
According to these results, HCG, HPL, and SP-1 are specifically synthesized and
secreted by normal or neoplastic syncytiotrophoblasts Malignant tumors originated from
other cells or tissues than trophoblastic cells show elevated serum concentration of these
hormones are only evident in the presence of syncytiotrophoblastic giant cells among the
tumor cells.
