Core Tip

Core Tip: Choriocarcinoma is a highly malignant trophoblastic tumor. Depending on the disease site, the clinical manifestations of choriocarcinoma are diverse and unique in each case, making diagnosis a challenge. We report the case of a patient with choriocarcinoma that metastasized to the lumbar muscle and caused symptoms similar to those of an ectopic pregnancy. Considering the lumbar metastasis of choriocarcinoma, 6 courses of cisplatin, dactinomycin, and etoposide chemotherapy were given after surgery. The patient's serum β-human chorionic gonadotropin level decreased to normal and the mixed echogenic mass in the lumbar muscle decreased after the 5th course of chemotherapy, and her symptoms disappeared.
