Human Chorionic Gonadotrophin (hCG) is mainly a product of the syncytiotropoblastic cells of the placenta although it is also secreted, in lesser quantities, by cytotrophoblastic cells and several nonplacental tissues. It is produced in gestational trophoblastic neoplasms (GTN) and maybe seen in nontrophoblastic neoplasms (Stenman, 2006). hCG is essential in pregnancy as it promotes transformat...

Molar pregnancy is a gestational trophoblastic disease that belongs to the category of precancerous lesions. On the other end of the spectrum are gestational trophoblastic neoplasms such as invasive mole, choriocarcinoma, placental site trophoblastic tumor and epithelioid trophoblastic tumor, which are considered malignant tumors. Based on defined histopathological criteria, molar pregnancy is ...

Gestational trophoblastic disease includes hydatidiform mole (complete and partial) and gestational trophoblastic neoplasia (invasive mole, choriocarcinoma, placental site trophoblastic tumor, and epithelioid trophoblastic tumor). The epidemiology, pathology, clinical presentation, and diagnosis of each of these trophoblastic disease variants are discussed. Particular emphasis is given to manag...

OBJECTIVE This study was undertaken to determine whether the expressions of 3 proliferation markers (Ki-67, proliferating cell nuclear antigen, and silver-staining nucleolar organizer regions) and of p53 tumor protein could differentiate spontaneous abortions from gestational trophoblastic diseases and also discriminate among gestational trophoblastic disease subgroups. STUDY DESIGN Twenty-tw...

background : gestational trophoblastic neoplasia (gtn) refers to malignant lesions that arise from abnormal proliferation of placental trophoblast. even in its metastatic forms gtn is curable with a cure rate of 90-100 %. currently, methotrexate with or without folic acid, andactinomycin d is recommended for low risk gtn. the aim of this study is to compare the efficacy of methotrexate and acti...

OBJECTIVES: Doppler ultrasonography can be used to assess neoangiogenesis, a characteristic feature of postmolar gestational trophoblastic neoplasia. However, there is limited information on whether uterine artery Doppler flow velocimetry parameters can predict gestational trophoblastic neoplasia following a complete hydatidiform mole. The purpose of this study was as follows: 1) to compare ute...

UNLABELLED Doppler ultrasound is a non-invasive method for evaluating vascularization and is widely used in clinical practice. Gestational trophoblastic neoplasia includes a group of highly vascularized malignancies derived from placental cells. This review summarizes data found in the literature regarding the applications of Doppler ultrasound in managing patients with gestational trophoblasti...

partial or complete mole affects one in 1000  pregnancies.partial mole is a rare form of ectopic pregnancy. there was a married woman,gravid 4,parity 1,abortion 1,and she had past medical history 0f right ectopic pregnancy.she had left ectopic pregnancy and was treated by laparascopic left salpyngectomy after failure of intramascular methotrexate treatment.after surgery  the pathology exam show...
