Molecular distinction of consecutive molar pregnancies.

Molecular and Immunohistochemical Characteristics of Complete Hydatidiform Moles

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 ...

A Novel Mutation in NLRP7 Related to Recurrent Hyda-tidiform Mole and Reproductive Failure

Objective Hydatidiform mole (HM) is an abnormal human pregnancy with excessive trophoblastic proliferation and abnormal embryonic development, which is divided into two Complete (CHM) and Partial (PHM) groups. One subcategory of the CHMs is recurrent and familial, which is known as biparental hydatidiform mole (BiHMs) or recurrent hydatidiform mole (RHM). NLRP7 and KHDC3L, two maternal-effect g...

Outcome of Subsequent Pregnancies in Familial Molar Pregnancy

Recurrent pregnancy loss

Recurrent pregnancy loss (RPL) refers to the consecutive loss of three or more clinically recognized pregnancies prior to the 20th week of gestation (excluding ectopic, molar and biochemical pregnancies). RPL is classified into two categories: primary RPL, which consists of repeated miscarriages in which a pregnancy has never been carried to viability; and secondary RPL, in which a live birth h...

Flow Cytometric DNA Analysis and Histopathologic Re-Evaluation of Paraffin Embedded Samples from Hydatidiform Moles and Hydropic Abortions

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...
