The trophoblastic tumor category was expanded by the addition of epithelioid trophoblastic tumor and cystic trophoblastic tumor.
Because the subsequent prolongation of thyroid function impairment could induce respiratory insufficiency and in molar pregnancy with hyperthyroidism, patients have encountered acute cardiopulmonary distress following suction evacuation under general anesthesia and massive trophoblastic embolism, death may occur (10, 11).
There are also specific recommendations for treatment of two even rarer intermediate trophoblastic tumor types: placental-site trophoblastic tumor and epithelioid trophoblastic tumor.
There were several differential diagnoses, such as cesarean scar pregnancy, retention placenta accreta, and gestational trophoblastic disease.

A study reported that ADAMTS-12 is abundantly expressed in invasive human trophoblastic cells, and the decreased or abolished expression of ADAMTS-12 leads to a decrease in the invasive behavior of the trophoblastic cells, indicating that ADAMTS-12 is critical in the regulation of trophoblast invasion (10).
Degenerative changes in the form of trophoblastic apoptosis were found in placentas from pregnancies complicated by fetal growth restriction, resulting from hypoxia (Heazell & Crocker, 2008); Jeschke et al.
The potential diagnosis of hydatidiform mole is often made by ultrasound, but histological examination of the evacuated material is essential to confirm the diagnosis.[7] In our case, empty uterus coexisting with high level of [sz]-HCG suggested first an ectopic pregnancy, and gestational trophoblastic disease (GTN) was less probable.
Preoperative diagnosis of PP was confirmed as extreme trophoblastic invasion that involved the serosa of the uterus during postoperative histopathologic evaluation.
Gestational trophoblastic disease (GTD) is a spectrum of disorders that arise from the placental trophoblast [18, 19].
