Spontaneous uterine perforation of choriocarcinoma with negative beta-human chorionic gonadotropin after chemotherapy

To report an extremely rare case of spontaneous uterine perforation of choriocarcinoma with negative beta-human chorionic gonadotropin [beta-hCG] post-chemotherapy. We present a 35-year-old choriocarcinoma patient whose serial serum beta-hCG levels following a fifth course of chemotherapy had been within the normal range, but who developed spontaneous uterine perforation with intra-abdominal hemorrhage after eight courses of combined chemotherapy. The patient then underwent an emergency hysterectomy and survived. Patients with persistent focus of disease in the uterus might experience uterine perforation even after adequate chemotherapy, and therefore, the follow-up for patients after chemotherapy is very important
