A metastatic invasive mole arising from iatrogenic uterus perforation

Abstract

Abstract Background Invasive mole derives from hydatidiform mole, but its pathogenesis remains unknown. Invasive mole arising from iatrogenic uterine perforation has not been reported yet. Case presentation A reproductive woman was admitted because she suffered form severe abdominal pain and acute intra-abdominal hemorrhage after suction evacuation due to misdiagnosis as inevitable abortion. The patient underwent hysteroscopy and laparoscopy, by which an iatrogenic uterine perforation and omentum and pelvic peritoneum metastases were confirmed. All lesions were removed and the final pathological diagnosis was metastatic invasive mole. The patient underwent post-operative chemotherapy with methotrexate and presented a good prognosis. Conclusion Invasive mole arising form iatrogenic uterine perforation displays an unusual metastatic manner other than general invasive moles. The prevention of uterine perforation should be emphasized during suction evacuation for mole pregnancy
