Context .- The placenta is an important component in understanding the fetal response to intrauterine Zika virus infection, but the pathologic changes in this organ remain largely unknown. Hofbauer cells are fetal-derived macrophages normally present in the chorionic villous stroma. They have been implicated in a variety of physiological and pathologic processes, in particular involving infectious agents. Objectives .- To characterize the fetal and maternal responses and viral localization in the placenta following Zika virus transmission to an 11 weeks' gestation fetus...

Gestational trophoblastic disease (GTD) is an abnormal proliferation of trophoblastic tissue during pregnancy. It is a disease of reproductive age, and a few cases have also been seen in women with advanced age, although it is extremely rare in postmenopausal women. Here, we describe an uncommon case of complete hydatidiform mole (CHM) in a postmenopausal woman, who has presented to us with complaints of bleeding per vagina, vomiting with 22 weeks size gravid uterus. Ultrasound finding along with raised serum beta-human chorionic gonadotropin (β-HCG) 400,000 mIU/ml suggested the diagnosis of CHM...

INTRODUCTION: Placental ischemia can be pre-placental (maternal), placental or post-placental (fetal), with corresponding changes in villous vasculature. Hydrops fetalis (HF) resulting from hemoglobin (Hb) Bart disease can serve as a model for intrauterine hypoxia, and placentas from such cases show a distinctive peripheral villous stromal myofibroblastic hypercellularity (PVSH). We hypothesized that Hb Bart disease, which results in profound fetal hypoxia, would lead to placental hypoxia on a post-placental basis...

Background Spontaneous abortion refers to a pregnancy that ends spontaneously before the fetus has reached a viable gestational age or expulsion or extraction of an embryo or fetus weighing 500 g or less from its mother. The Maternal Mortality Morbidity Survey of Nepal 2008/09 reported that 7% of maternal deaths in Nepal were due to complications related to abortion. Objective The main objective of this study was to examine the histopathological changes in the chorionic villi and endometrial decidual tissue in products of conception obtained from women with spontaneous abortion...

The clinical significance and etiology of the chorionic bump remain unclear. We describe two pregnancies characterized by chorionic bumps, which subsequently were diagnosed with a complete mole and trisomy 18, respectively. We hypothesize that placental pathology, including edema and hydropic villi, may contribute to or cause the sonographic finding of some chorionic bumps. An association between chorionic bumps and aneuploidy awaits future study. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 44:452-454, 2016...

BACKGROUND: Hydatidiform moles occur in approximately 1 in 1,500 pregnancies; however, early miscarriages or spontaneous abortions may not be correctly identified as molar pregnancies due to poor differentiation of chorionic villi. METHODS: The current clinical testing algorithm used for the detection of hydatidiform moles uses a combination of morphological analysis and p57 immunostaining followed by ploidy testing to establish a diagnosis of either a complete or partial molar pregnancy...

"The battle of the sexes begins in the zygote" W. Reik and J. Walter. Complete hydatidiform mole (CHM) is a pathology of the placenta with androgenetic diploid origin (chromosomes only from paternal origin). Placental villi present an abnormal hyperproliferation and hydropic degeneration associated with the absence of embryo. Three mechanisms can be envisaged at its origin: (1) destruction/expulsion of the female pronucleus at the time of fertilization by one or two spermatozoa, the former being followed by an endoreplication of the male pronucleus (homozygous mole), (2) a triploid zygote (fertilization by two spermatozoa) leading to a haploid and a diploid clones...

The hydatidiform mole (HM) is a placental pathology of androgenetic origin. Placental villi have an abnormal hyperproliferation event and hydropic degeneration. Three situations can be envisaged at its origin: 1. The destruction/expulsion of the female pronucleus at the time of fertilization by 1 or 2 spermatozoa with the former being followed by an endoreplication of the male pronucleus leading to a complete hydatidiform mole (CHM) 2. A triploid zygote (fertilization by 2 spermatozoa) leading to a partial hydatidiform mole (PHM) but can also lead to haploid and diploid clones...

Fetoplacental hydrops is the final stage of several pathological conditions in which the placenta and umbilical cord become edematous and the fetus develops an anasarcatic state characterized by an excessive accumulation of extravascular fluids in at least two serous cavities of the body. It is a common histological finding of stillbirth, characterized by the appearance of markedly edematous villi, suggesting an increased interstitial fluid accumulation. The recent improved knowledge of lymphangiogenesis and the availability of monoclonal antibodies selectively labeling lymphatic endothelium lead to the hypothesis that villous edema is essentially a lymphedema from defective lymphatic function following inadequate villous blood circulation...

The pathogenetic mechanism underlying the hydropic change in complete hydatidiform moles (CHMs) is poorly understood. A growing body of data suggests that pericytes play a role in vascular maturation. Since maturation of villous stromal vessels in CHMs is markedly impaired at early stages, we postulated that a defect in pericytes around stromal vessels in chorionic villi might cause vascular immaturity and subsequent hydropic change. To investigate this, we examined several markers of pericytes, namely, α-smooth muscle actin (α-SMA), platelet-derived growth factor receptor-β (PDGFR-β), and desmin, in 61 normally developing placentas and 41 CHMs with gestational ages of 4-12 weeks...

We describe an extremely rare case of congenital neuroblastoma with placental involvement. A fetus with a left abdominal mass detected during ultrasonography at 23 weeks' gestation developed hydrops fetalis by 26 weeks' gestation. The mother developed hypertension at 26 5/7 weeks' gestation. Based on a clinical diagnosis of pregnancy-induced hypertension, labor was induced at 26 6/7 weeks. However, intrauterine fetal death was diagnosed during delivery. Postmortern examination revealed a solid tumor at the site of the left adrenal gland...

A 34-yr-old woman presented with missed abortion at 10 wk of estimated clinical gestational age and underwent dilation and curettage. Gross and microscopic evaluation of the uterine contents revealed the presence of mildly hydropic, dysmorphic chorionic villi, with occasional trophoblastic pseudo-inclusions. The morphologic features raised the suspicion for partial hydatidiform mole, and DNA genotyping was performed using the AmpFlSTR Identifiler PCR Amplification system. The chorionic villous tissue showed unique alleles - not present in the maternal decidual tissue - at 12 of the 15 short tandem repeat loci, and 8 loci showed 2 unique alleles, suggesting a diandric, paternal-only genome...

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 the occurrence of a hydatidiform mole within ectopic gestational tissue is rare. It is important to differentiate a hydatidiform mole from a conventional ectopic pregnancy, particularly in infertile women who have a history of ovulation induction...

Placental mesenchymal dysplasia (PMD) rarely complicates with pregnancy. A 30-year-old woman, gravida 3, para 3, presenting with placentomegaly, was referred to our department at 18 weeks of gestation. An ultrasonography revealed a normal fetus with a large multicystic placenta, measuring 125 × 42 × 80 mm. The border between the lesion and normal region was not clear. Color doppler revealed little blood flow in the lesion. Magnetic resonance imaging revealed normal fetus and a large multicystic placenta...

Fetal congenital chylothorax is a rare condition that occurs sporadically or can be associated with abnormal karyotype or structural chromosomal anomalies. We report a unique case of fetal congenital bilateral chylothorax associated with mosaicism 47,XXX/46,XX. A female fetus affected by massive bilateral hydrothorax and ascites was diagnosed at 34(+1) weeks of gestation. Previous ultrasonographic exams were completely normal. Immune causes of hydrops were excluded. Elective cesarean section was performed soon after bilateral thoracocentesis...

UNLABELLED: This study aimed at investigating ultrasonographic features of partial hydatidiform mole to establish a proper diagnosis. PATIENTS AND METHODS: This was a retrospective study of 70 pregnancies which were divided into two groups: group I--35 pregnant women with a molar pregnancy diagnosed in the first trimester; group II--35 pregnant women with physiological pregnancy spontaneously aborted in the first trimester caused by the cervical insufficiency. Evacuation of the uterus by uterine suction or curettage and pathomorphological analysis ofovular tissue were conducted in both groups...

In this article, the authors present a case of intrauterine foetal death (IUFD). The post-mortem histologic examination revealed placental mesenchymal dysplasia (PMD), a rare human placental disorder. Moreover, cases of PMD are often misdiagnosed as partial mole. The mother was a 26-year-old Italian, whose pregnancy, her first, had been uneventful until week 34⁺⁴ of gestation when IUFD suddenly occurred. The 2350 g male foetus showed no external abnormalities and the karyotype was 46, XY. The placenta weighed 450 g, the chorionic disk was round shaped, measuring 19...

A total of 297 samples of hydropic villi were classified according to DNA polymorphisms as androgenetic moles, dispermic triploids, or biparental diploids. A subset of 267 appropriate samples was included in the study. Most of the macroscopically diagnosed complete mole cases were genetically androgenetic in origin. The partial mole cases consisted of 30 androgenetic moles and 12 dispermic triploids. For the 59 cases macroscopically categorized as hydropic abortion, the genetic analysis revealed 38 androgenetic moles, seven dispermic triploids and 14 biparental diploids...

STUDY QUESTION: How does tetraploidy develop in hydatidiform moles (HMs), and what is the frequency of the different origins? SUMMARY ANSWER: Most molar pregnancies with tetraploid cells appear to be produced by somatic endoreduplications, while a minority originate from a tetraploid zygote. The frequency of zygotic tetraploidy was estimated to be 0.7%. WHAT IS KNOWN ALREADY: The parental origin of the genome in tetraploid HMs has only been evaluated in a few cases, most showing three genome sets from the father (PPPM)...
