title: Pituitary metastasis of choriocarcinoma: A case report.
abstract: Choriocarcinoma is an aggressive obstetric or gynecological neoplasm with a high malignant potential. It is a form of gestational trophoblastic disease and often secondary to hydatidiform mole, and intrauterine or ectopic pregnancy. Choriocarcinoma has a proclivity to metastasize to the lung, vagina, pelvis or liver in over 50% of patients, which always occurs in the early stage of the disease. With an appropriate amount of chemotherapy, the tumor may be treated effectively. However, pituitary metastasis of choriocarcinoma is extremely rare. To the best of our knowledge, no cases of choriocarcinoma metastasizing to the pituitary have been cited previously. Here, we report a case of choriocarcinoma that presented with pituitary metastasis.
