2. Conclusion Intraplacental choriocarcinoma is a rare tumor. To best of our knowledge, this is no case report of intraplacental choriocarcinoma with maternal and infant metastases in Chinese literature.

3. Results:ERCC2 gene expression in human choriocarcinoma cell line JAR was evidently lower than in human cytotrophoblast cells.

4. Four malignant GCTs ( 1 seminoma, 1 choriocarcinoma, and 2 yolk - sac tumors ) have been treated in our hospital.
