•Gestational trophoblastic neoplasia can arise during the first trimester originating from trophoblasts of concurrent pregnancy.•Intraplacental choriocarcinoma can be developed from trophoblasts of a previous pregnancy.

Background: Methotrexate is used in the treatment of Low-risk Gestational Trophoblastic Neoplasia. The purpose of this study was to compare the therapeutic responses and side effects of two therapeutic methods which were prescribed for patients suffering from Low-risk Gestational Trophoblastic Neoplasia. One method was the daily use of Methotrexate-Folic Acid (for 8 da...

Introduction: Gestational trophoblastic disease (GTD) includes hydatiform mole, choriocarcinoma, placental site tumor, and epithelial tumor. Also, molar pregnancy can happen as an ectopic pregnancy. The coincidence of these complicated pregnancies seems to occur extremely rarely. Case presentation: Here, we presented a 26-year-old woman, nulli gravida with the first presentation intrauterine co...

OBJECTIVE To study the potential of long interspersed element-1 (LINE-1) methylation change in the prediction of postmolar gestational trophoblastic neoplasia (GTN). METHODS The LINE-1 methylation pattern from first trimester placenta, hydatidiform mole, and malignant trophoblast specimens were compared. Then, hydatidiform mole patients from 11999 to 2010 were classified into the following 2 ...

Invasive mole is a benign gestational trophoblastic disease that arises from the myometrial invasion of any gestational event via direct extension through tissue or vascular structures. Invasive mole (and other gestational trophoblastic diseases) may present with life-threatening complications including uterine perforation, excessive bleeding, acute hemoperitoneum, and abdominal pain. We report...

Gestational trophoblastic neoplasms (GTNs) are a rare group of neoplastic diseases composed of choriocarcinomas, placental site trophoblastic tumors (PSTTs) and epithelioid trophoblastic tumors (ETTs). Since these tumors are derivatives of fetal trophoblastic tissue, approximately 50% of GTN cases are expected to originate from a male conceptus and carry a Y-chromosomal complement according to ...

Introduction. Gestational trophoblastic disease represents a distinguished group of disorders that are derived from placental tissue aroused abnormal fertilization. Choriocarcinoma is malignant human chorionic gonadotropin-producing epithelial tumor arising villous trophoblast. The choice the chemotherapy regime based on International Federation Gynecology and Obstetrics stage World Health Orga...

Gestational Trophoblastic Neoplasia (GTN) is a rare disease originating from pregnancy events that have varied incidences and clinical manifestations based on regional variation. We are reporting case of 36-year-old woman with Invasive mole Central India who presented abnormal uterine bleeding severe anemia. She had three full-term vaginal deliveries 2 spontaneous abortions, the last conception...

BACKGROUND It may be difficult to differentiate the consecutive occurrence of two independent molar pregnancies from gestational trophoblastic neoplasia after the initial molar pregnancy, especially when the interval between them is short. CASE A 25-year-woman who had had a complete hydatidiform mole 6 months earlier presented with a 6-week history of secondary amenorrhea. Serum human chorion...
