Evaluation and analysis of influencing factors of placental mesenchymal dysplasia diagnosed using prenatal ultrasonography and pregnancy outcomes: case series.

Background: Placental mesenchymal dysplasia (PMD) is a rare placental vascular malformation of unknown etiology. PMD may coexist with a healthy fetus, and its ultrasound appearance is similar to that of a hydatidiform mole, especially the partial type. Prenatal ultrasonography is vital for accurate diagnosis of these conditions.

New insight on etiology: A chorionic bump with partial mole pregnancy case report from Syria.

This case report presents the association of a chorionic bump with a partial mole pregnancy in a 37-year-old G3P2 woman. The differential diagnosis of a partial mole was considered after transvaginal ultrasonography revealed a chorionic bump. Subsequent pathological analysis confirmed the diagnosis.

Molecular Basis of Hydatidiform Moles-A Systematic Review.

Gestational trophoblastic diseases (GTDs) encompass a spectrum of conditions characterized by abnormal trophoblastic cell growth, ranging from benign molar pregnancies to malignant trophoblastic neoplasms. This systematic review explores the molecular underpinnings of GTDs, focusing on genetic and epigenetic factors that influence disease progression and clinical outcomes. Based on 71 studies identified through systematic search and selection criteria, key findings include dysregulations in tumor suppressor genes such as , aberrant apoptotic pathways involving (B-cell lymphoma), and altered expression of growth factor receptors and microRNAs (micro-ribose nucleic acid).

Hypermethylated RASAL1's promotive role in chemoresistance and tumorigenesis of choriocarcinoma was regulated by TET2 but not DNMTs.

Background: Patients with choriocarcinoma (CC) accompanying chemoresistance conventionally present a poor prognosis. Whether ras protein activator like-1 (RASAL1) functions as a tumor promoter or suppressor depends on tumor types. However, the role of RASAL1 in process of chemoresistance of CC and underlying molecular mechanism remain elusive.

Tubal ectopic molar pregnancy: A case report.

Background: Ectopic molar pregnancy (EMP) is a rare form of gestational trophoblastic disease that occurs when a hydatidiform mole implants outside the uterus.

Case Presentation: We describe a 35-yr-old woman with mild abdominal pain, delayed menstruation for 2 months, and high beta-human chorionic gonadotropin levels. Sonography revealed a heterogeneous hyperechoic mass in the left adnexa and fluid in the endometrial cavity, suggestive of a tubal EMP.

Reappraisal and refined diagnosis of ultrasonography and histological findings for hydatidiform moles: a multicentre retrospective study of 821 patients.

Aims: Specific identification of a hydatidiform mole (HM) and subclassification of a complete hydatidiform mole (CHM) or partial hydatidiform mole (PHM) are critical. This study aimed to reappraise the diagnostic performance of ultrasonography and histology with a refined diagnosis.

Methods: This was a retrospective, multicentre cohort study of 821 patients with histologically suspected HM specimens.

Diandric triploid partial mole versus digynic nonmolar triploidy: is morphological assessment sufficient for the diagnostic distinction?

Aims: Diagnostic separation of diandric triploid gestation, i.e. partial mole from digynic triploid gestation, is clinically relevant, as the former may progress to postmolar gestational trophoblastic neoplasia.

Analysis of Fertility Prognosis and Risk Factors in Patients Post-Gestational Trophoblastic Disease.

To retrospectively analyze the fertility outcomes and prognosis of gestational trophoblastic disease (GTD) patients, providing a basis for targeted fertility guidance and counseling. 82 GTD patients of childbearing age who received treatment at the Obstetrics and Gynecology Department of Lanzhou University First Hospital from January 2016 to January 2023 were stratified into re-pregnancy (n = 20) and non-re-pregnancy (n = 33) cohorts based on their pregnancy outcomes. The impacts of various factors on pregnancy outcomes were subsequently evaluated, encompassing the rates of subsequent pregnancies, live births, miscarriages, ectopic pregnancies, and ongoing pregnancies.

Placental Mosaicism in Multiple Gestation: Complete Hydatidiform Mole with Coexisting Twin Fetus.

Hydatidiform mole coexistent with a live fetus (CMCF) is a rare entity occurring in 1:20,000 to 1:100,000 pregnancies. Three mechanisms of this type are possible: (1) a singleton pregnancy consisting of partial mole with a triploid fetus, (2) a twin gestation consisting of an androgenic complete hydatidiform mole with a biparental diploid fetus, and (3) a twin gestation consisting of a biparental diploid fetus with a normal placenta and a partial hydatidiform mole (PHM) with a triploid fetus. The abnormal triploid fetus in a partial mole tends to die in the first trimester while the fetus coexisting with a complete or partial mole in the dizygotic twin pregnancy has a chance to survive.

Mixed Gestational Trophoblastic Tumors-Challenging Clinicopathological Presentations.

Mixed gestational trophoblastic tumors are exceptionally rare and have variable clinicopathological presentations. We report 3 such tumors with different combinations of choriocarcinoma (CC), placental site trophoblastic tumor (PSTT), and epithelioid trophoblastic tumor (ETT). The patients' age ranged from 38 to 44 years.

Heterotopic pregnancy: a case report of intrauterine hydatidiform mole with tubal pregnancy.

We herein report a rare case of simultaneous intrauterine molar pregnancy and tubal pregnancy. A woman of childbearing age who had never been pregnant underwent an ultrasound examination 70 days after the onset of menopause. She had a history of ovulation induction.

Giant complete hydatidiform mole: a case report and review of the literature.

Background: This case describes the youngest patient documented in the literature who presented with a giant hydatidiform mole, effectively addressed through conservative treatment.

Case Presentation: Our department received a 20-year-old Caucasian patient who was admitted due to significant metrorrhagia in an undisclosed pregnancy. During examination, we identified a massive, highly vascularized hydatidiform mole measuring 22 cm (cm).
