background: classification of molar gestation into complete hydatidiform mole (chm) and partial hydatidiform mole (phm) is done according to clinical, ultrasonographic, histologic and genetic criteria. however, making a distinction between chm and phm using histologic criteria alone may be difficult and several studies have shown that misclassifications are frequent, even for experienced pathol...

Gestational trophoblastic disease (GTD) is a spectrum of cellular proliferations arising from the placental villous trophoblasts encompassing four main clinicopathologic forms : hydatidiform mole (complete and partial), invasive mole, choriocarcinoma and placental site trophoblastic tumor (PSTT). Placental site trophoblasic tumours (PSTT) are rare and usually diagnosed after dilatation and cure...

tubal pregnancies are common but presence of hydatidiform mole in tube is a rare entity. a woman of 53years presented with acute abdomen, preoperative pregnancy test was positive and ultrasonography suspected the case as hydatidiform mole in right tube. the patient was treated with total abdominal hysterectomy with bilateral salpingo-oophorectomy as her family was completed. subsequent histopat...

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 ...

A review of gestational trophoblastic disease diagnosed at the Department of Pathology, University Hospital, Kuala Lumpur from January 1989 to December 1990 using established histological criteria showed 25 complete hydatidiform moles (CHM), 11 partial hydatidiform moles (PHM), 1 invasive mole and 2 choriocarcinoma. The ages of the patients with CHM ranged from 21 to 43 years (mean = 28.5 years...

The relationship between parental constitutional chromosome abnormalities and the development of hydatidiform mole was evaluated in series from four institutions. Karyotype analysis was performed on blood samples from 237 patients with a pathological diagnosis of complete mole and 217 of their spouses. One patient was found to have a constitutional balanced translocation, t(11;18), while one sp...

Introduction: Gestational trophoblastic disease (GTD) consists of group of disorders having pathology of abnormal trophoblastic proliferation ranging from hydatidiform mole to gestational trophoblastic neoplasia. Based on differences in morphology, histopathology, karyotype and clinical features, hydatidiform mole can be categorized into partial and complete moles. Molar pregnancy incidence var...

Background Distinction of hydatidiform moles (HMs) from non-molar abortions and sub-classification of HMs are important for clinical practice; yet, diagnosis based solely on morphology is affected by interobserver variability. The objective of this study was to determine the role of DNA flow cytometry in distinguishing molar from non-molar pregnancies. MaterialsAndMethods This retrospective stu...

Hydatidiform moles are abnormal gestations characterized by the presence of hydropic changes affecting some or all of the placental villi. Hydatidiform moles arise as a result of the fertilization of an abnormal ovum. In this report, the patient was a 29 year old Asian woman who had induction of ovulation with letrozol. Since the majority of molar gestations arise within the uterine cavity thus...
