Diagnosis and treatment of placental site trophoblastic tumor.

Abstract

Here we report a case of a placental site trophoblastic tumor in a 36 year old Chinese woman, 31 months following a prior normal pregnancy. Her clinical presentation and ultrasound findings were uncharacteristic; and the final definitive diagnosis was established based on histological examination in conjunction with immunohistochemistry studies and a normal beta human chorionic gonadotropin level. The tumor exhibited high grade histological features with tumor necrosis, nuclear atypia and high mitosis. The patient was successfully treated with hysterectomy with pre- and post-operative chemotherapy.
