Choriocarcinoma of the liver is a very rare tumor that appears to originate in the placenta during gestation and presents with a liver mass in the first few months of life. Metastasis from placenta to maternal tissues occurs in many cases, necessitating beta-human chorionic gonadotropin (beta-hCG) testing of the mother. Infants are often anemic and can be unstable at presentation due to hemorrhage from the tumor. Clinical diagnosis may be made without biopsy based on extremely high serum beta-hCG levels and normal alpha-fetoprotein levels for age. Initial surgical removal of the tumor mass may be difficult because of its friability and hemorrhagic tendency. Often surgical removal of the residual primary tumor is performed after neoadjuvant chemotherapy.
Maternal gestational trophoblastic tumors are exquisitely sensitive to methotrexate, and many women, including those with distant metastases, are cured with single-agent chemotherapy. Maternal and infantile choriocarcinoma both come from the same placental malignancy. The combination of cisplatin, etoposide, and bleomycin, as used in other pediatric germ cell tumors, has been effective in some patients and is followed by resection of residual mass. Use of neoadjuvant methotrexate in infantile choriocarcinoma, although often resulting in a response, has not been uniformly successful.
