A Rare Case of Early Transformation of Gestational Trophoblastic Neoplasia Following Molar Pregnancy.

Am J Case Rep 2021 May 11;22:e930789. Epub 2021 May 11.

Department of Obstetrics and Gynecology, Faculty of Medicine, Padjadjaran University - Dr. Hasan Sadikin Hospital, Bandung, Indonesia.

BACKGROUND Gestational trophoblastic disease (GTD) encompasses a group of disorders that arise from abnormal growth of trophoblastic tissue. The spectrum of GTD includes 2 major groups: benign and malignant. The benign form is a hydatidiform mole, either complete or partial; the malignant forms, referred to as gestational trophoblastic neoplasia (GTN), consist of invasive moles, choriocarcinomas, placental site trophoblastic tumors, and epithelioid trophoblastic tumors.

Cytological features of a complete hydatidiform mole in a cervicovaginal smear: A case report.

Diagn Cytopathol 2021 May 7. Epub 2021 May 7.

Department of Histopathology, The Indus Hospital, Karachi, Pakistan.

Exfoliated trophoblastic cells can be seen in a cervicovaginal smear in cases of normal pregnancy or gestational trophoblastic disease (GTD) and can mimic high-grade squamous intraepithelial lesion (HSIL) or malignancy. Although they appear highly anaplastic, cytological features such as high nuclear to cytoplasmic ratio, irregular nuclear contours and scanty basophilic cytoplasm admixed with cytologically benign squamoid and endocervical cells can aid in differentiating them from malignant cells. We present a case of a 37-year-old woman with abnormal uterine bleeding for 3-months. Read More

Rare Complete Hydatidiform Mole With p57 Expression in Villous Mesenchyme: Case Report and Review of Discordant p57 Expression in Hydatidiform Moles.

Int J Gynecol Pathol 2021 Apr 23. Epub 2021 Apr 23.

ProPath (K.M.M.) Department of Obstetrics and Gynecology (V.R. and D.H.C.) Department of Pathology, Division of Cytogenetics (P.K.) Department of Pathology, Division of Gynecologic Pathology (K.C., K.G., and D.H.C.), UT Southwestern Medical Center, Dallas, Texas Departments of Pathology and Gynecology & Obstetrics, The Johns Hopkins Medical Institutions, Baltimore, Maryland (B.M.R.).

Complete hydatidiform mole (CHM) is a premalignant proliferative disease of the placenta characterized by misexpression of imprinted gene products, most notably p57. The majority of CHM exhibit immunohistochemical absence of p57 protein in villous mesenchyme (VM) and cytotrophoblast (CT) and are thus p57 VM/CT concordant. However, some gestations show loss of p57 in only VM or CT, either in all chorionic villi or a subset thereof (VM/CT discordant). Read More

Trajectory clustering using mixed classification models.

Stat Med 2021 Apr 7. Epub 2021 Apr 7.

Université de Lyon, Lyon, France.

Trajectory classification has become frequent in clinical research to understand the heterogeneity of individual trajectories. The standard classification model for trajectories assumes no between-individual variance within groups. However, this assumption is often not appropriate, which may overestimate the error variance of the model, leading to a biased classification. Read More

An integrated model of preeclampsia: a multifaceted syndrome of the maternal cardiovascular-placental-fetal array.

Am J Obstet Gynecol 2021 Mar 9. Epub 2021 Mar 9.

Department of Obstetrics and Gynecology, Hadassah-Hebrew University Medical Center, Jerusalem, Israel.

Maternal tolerance of the semiallogenic fetus necessitates conciliation of competing interests. Viviparity evolved with a placenta to mediate the needs of the fetus and maternal adaptation to the demands of pregnancy and to ensure optimal survival for both entities. The maternal-fetal interface is imagined as a 2-dimensional porous barrier between the mother and fetus, when in fact it is an intricate multidimensional array of tissues and resident and circulating factors at play, encompassing the developing fetus, the growing placenta, the changing decidua, and the dynamic maternal cardiovascular system.

Genetics of gestational trophoblastic disease.

Best Pract Res Clin Obstet Gynaecol 2021 Feb 2. Epub 2021 Feb 2.

Trophoblastic Tumour Screening and Treatment Centre, Faculty of Medicine, Imperial College London, Charing Cross Campus, Fulham Palace Road, London, W6 8RF, UK.

The abnormal pregnancies complete and partial hydatidiform mole are genetically unusual, being associated with two copies of the paternal genome. Typical complete hydatidiform moles (CHMs) are diploid and androgenetic, while partial hydatidiform moles (PHMs) are diandric triploids. While diagnosis can usually be made on the basis of morphology, ancillary techniques that exploit their unusual genetic origin can be used to facilitate diagnosis. Read More

Front Genet 2020 14;11:561720. Epub 2021 Jan 14.

BCNatal Department of Maternal-Fetal Medicine, Institute Gynecology, Obstetrics and Neonatology, Hospital Clínic de Barcelona, Barcelona, Spain.

To explore the use of a new molecular work-up based on the stepwise use of Quantitative Fluorescence PCR (QF-PCR) extended to eight chromosomes and single nucleotide polymorphism array (SNP-array) in chorionic villi obtained by chorionic villi sampling (CVS) offered to women experiencing an early pregnancy loss. During a 3-year period (January 2016-December 2018), CVS was offered to women experiencing an early pregnancy loss before the evacuation of the products of conception (POC) to retrieve chorionic villi, irrespective of the number of previous losses. A new molecular work-up was prospectively assayed encompassing a first QF-PCR round (with the 21, 18, 13, 7, X, and Y chromosomes), a second QF-PCR round (with the 15, 16, and 22 chromosomes), and a high resolution SNP-array in those cases with normal QF-PCR results.

[Persistent gestational trophoblastic disease following ectopic molar pregnancy].

Arkh Patol 2021 ;83(1):44-48

Moscow Regional Research Institute of Obstetrics and Gynecology of the Ministry of Health of the Moscow Region, Moscow, Russia.

A case of persistent gestational trophoblastic disease that developed after ectopic (cervical) pregnancy with complete hydatidiform mole (CHM) in a 56-year-old patient is presented. The diagnosis of CHM was made retrospectively based on immunohistochemical analysis of archival material using p57 and Ki67 antibodies. Observation shows the difficulty of objective diagnosis of hydatidiform mole in early pregnancy due to the lack of typical cystic transformation of the stroma of villi, focal proliferation of villous trophoblast.

Trophoblastic Disease Unit, Department of Histopathology, Charing Cross Hospital Imperial Nhs Trust, London, UK. Electronic address:

Hydatidiform mole (HM) affects around 1/1000 pregnancies, and in such cases the recurrence risk is around 1%, being greater for those with complete HM (CHM). Whilst most cases appear sporadic with unknown mechanisms, there is a distinct subgroup of patients who suffer recurrent pregnancy loss, including multiple recurrent CHM (familial recurrent biparental HM syndrome). The majority of these cases are related to maternal genetic mutations in genes related to the control of imprinting, specifically NALP7 and KHDC3L. Read More
