UNASSIGNED: Post-molar gestational trophoblastic neoplasia (pGTN) develops in about 15% to 20% of complete hydatidiform mole (CMH). Commonly, pGTN is diagnosed based on hCG monitoring following the molar evacuation. To date, no detailed information is available on how fast can pGTN develop from CHM. However, the concurrence of CHM and pGTN is extremely rare.
UNASSIGNED: A 29-year-old woman presented to the gynecology department with irregular vaginal bleeding and an elevated hCG serum level. Both ultrasound and MRI showed heterogeneous mass in uterine cavity and myometrium. Suction evacuation was performed and histologic examination of the evacuated specimen confirmed complete hydatidiform mole. Repeated ultrasound showed significant enlargement of the myometrium mass one week after the evacuation. pGTN with prognostic score of 4 was then diagnosed and multi-agent chemotherapy regimen implemented with a good prognosis.
UNASSIGNED: In rare cases, CMH can rapidly progress into pGTN. Imaging in combination with hCG surveillance seems to play a vital role guiding timely diagnosis and treatment in the specific condition. Low-risk gestational trophoblastic neoplasia (GTN) should be managed stratified according to the individual situation.

UNASSIGNED: Twin pregnancy combining a complete mole and a normal fetal pregnancy with its own healthy trophoblast is a rare entity. A partial molar pregnancy almost always ends in miscarriage due to a triploid fetus.
METHODS: We report the case of a 43-year-old female patient admitted for bleeding during the 20th week of pregnancy. Pelvic ultrasound showed the combination of a complete hydatidiform mole and a normal fetal pregnancy. The decision to medically terminate the pregnancy was taken after consultation with the family. Examination of the placenta and histological study confirmed the diagnosis of complete hydatidiform mole associated with a normal fetus. The evolution was uneventful.
UNASSIGNED: Twin pregnancy combining a complete mole and a normal fetal pregnancy with its own healthy trophoblast is a rare entity that should not be misdiagnosed. There is still no consensus in terms of therapeutic attitude, the dilemma remains and the decision should always include the couple after a thorough explanation of all the risks.
CONCLUSIONS: Our case reaffirms that to successfully manage this rare yet life-threatening condition, heterotopic pregnancy should be included in the differential diagnosis for any gravid women presenting with persistent abdominal pain, abnormal bleeding and/or extrauterine mass.

Epithelioid trophoblastic tumor (ETT) is a rare trophoblastic tumor originating from chorionic-type intermediate trophoblasts (ITs). It is usually associated with a prior gestational event. We present a 44-year-old woman who had unusual pregnancy related history. The patient received her second spontaneous abortion at the age of 25 years and had suffered from choriocarcinoma in left board ligament at the age of 29 years. She admitted no more treatment after 3 courses of multiagent chemotherapy when serum β-hCG returned to normal. Then she had Full-term delivery, induced abortion at the ages of 32, 33 years. The patient had high serum levels of beta-human chorionic gonadotropin (6587 IU/L). Microscopically, the tumor was composed of mainly mononuclear tumor cells, grew in cords, nests, and sheets within which were aggregates of hyaline material. Most were with distinct cell borders, eosinophilic cytoplasm. Immunohistochemical staining revealed strong diffuse reactivity for cytokeratins (AE1/AE3, CK18), P63, focal reactivity for beta-human chorionic gonadotropin, human placental lactogen, and inhibin-alpha. The Ki-67 index was 77%. The histological and immunohistochemical features were characteristic of epithelioid trophoblastic tumor. This is the first reported case of these two gestational trophoblastic tumor happened on one person with the intervening normal pregnancy.
