BACKGROUND: This case describes the youngest patient documented in the literature who presented with a giant hydatidiform mole, effectively addressed through conservative treatment.
METHODS: 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). We performed a surgical dilatation and curettage. The anatomopathological findings confirmed the presence of a complete hydatidiform mole (CHM). Following the established guidelines, we conducted weekly monitoring of human chorionic gonadotropin (hCG). Unfortunately, the patient discontinued the follow-up and became pregnant again before achieving hCG negativation.
CONCLUSIONS: This case suggests that conservative treatment is a viable option regardless of the size of gestational trophoblastic disease (GTD), especially when the preservation of fertility is a crucial consideration, as effectively demonstrated in our case.

BACKGROUND: Molar pregnancies, encompassing complete and partial moles, represent a rare and enigmatic gestational disorder with potential ethnic variations in incidence. This study aimed to investigate relations of ethnicity with risks of complete and partial molar pregnancies within an Israeli population while accounting for age differences.
METHODS: A retrospective study was conducted of data recorded during 2007-2021 in an academic medical center in Israel. The study population comprised 167 women diagnosed with complete or partial moles, for whom data were obtained through histological examination and P57 immunostaining. Maternal age and ethnicity were extracted from electronic medical records. Incidence rates were calculated per 10,000 live births, and a nested case-control study compared demographic characteristics and molar pregnancy incidences between Arab and Jewish women. Statistical analyses included age-adjusted comparisons, relative risk calculations and multivariate logistic regression.
RESULTS: The overall risk of molar pregnancy was 22 per 10,000 live births (95% confidence interval [CI] 18-25). Among Arab women, the overall risk was 21 (95% CI 17-25), and for PM and CM: 14 (95% CI 11-17) and 7 (95% CI 5-10), respectively. Among Jewish women, the overall risk was 23 (95% CI 18-29), and for PM and CM: 12 (95% CI 8-17) and 11 (95% CI 7-16), respectively. Among Arab women compared to Jewish women, the proportion of all the partial moles was higher: (65.3% vs. 51.6%, p = 0.05). The incidence of partial mole was higher among Arab than Jewish women, aged 35-39 years (26 vs. 8 per 10,000, p = 0.041), and did not differ in other age groups. After adjusting for age, the relative risk of partial moles was lower among Jews than Arabs (0.7, 95% CI 0.4-1.0, p = 0.053). For Arab compared to Jewish women, the mean age at molar pregnancies was younger: 31.0 vs. 35.1 years. However, other factors did not differ significantly between Arab and Jewish women with molar pregnancies. In multivariate analysis, Jewish ethnicity was significantly associated with a higher risk of complete molar pregnancies (OR = 2.19, 95% CI 1.09-4.41, p = 0.028).
CONCLUSIONS: This study highlights ethnic differences in molar pregnancy risk within the Israeli population. Jewish ethnicity was associated with a higher risk of complete molar pregnancies, while Arab women had a significantly higher risk of partial moles. These findings underscore the need to consider ethnicity when studying gestational disorders. Further research should seek to elucidate the underlying factors contributing to these differences.

OBJECTIVE: To systematically review the effect of contraceptive methods following gestational trophoblastic disease (GTD) on timing of beta-human chorionic gonadotropin (hCG) remission, risk of post-molar gestational trophoblastic neoplasia (GTN), risk of unintended incident pregnancy, and interactions between contraceptive methods and disease treatment.
METHODS: We conducted a search of primary literature with search terms related to GTD and contraception through April 2023 in PubMed and extrapolated our search to other platforms. Randomized controlled trials, observational studies and case reports were eligible for inclusion if they reported on patients with known GTD who received a contraceptive method for pregnancy prevention. Data was abstracted on our main outcomes of interest: timing of beta-hCG remission, risk of post-molar GTN, risk of unintended incident pregnancy, and interactions between contraceptive methods and cancer-directed systemic disease treatment (e.g., chemotherapy). At least two authors reviewed manuscripts at each screening stage with consensus reached before data extraction. Quality assessment checklists were used to assess risk of bias for the different study types.
RESULTS: Five thousand one hundred and five studies were identified in the database search, of which 42 were included for analysis. Eight thousand two hundred and ninety four participants were evaluated. Over half of the studies were case reports and only two were randomized controlled trials. While there was sparse data on all outcomes, no differences were noted in beta-hCG monitoring, risk of post-molar GTN or incident pregnancies between different contraceptive types. Interactions between contraceptive methods and cancer-directed systemic disease treatment (e.g., chemotherapy) or specific adverse events of contraceptive methods were not identified.
CONCLUSIONS: Data on contraceptive use following GTD is limited, but use of both hormonal and non-hormonal modern contraceptive methods appears safe. Counseling patients on the full range of contraceptive methods is important to help patients achieve their reproductive health goals and minimize the risk of disease progression through incomplete beta-hCG monitoring prior to future pregnancy.
CONCLUSIONS: Hormonal and non-hormonal contraceptive options may be used by patients following gestational trophoblastic disease without apparent changes in beta-hCG regression or risk of post-molar gestational trophoblastic neoplasia.

Point of care ultrasound (POCUS) is a useful modality to initially identify a molar pregnancy. In this case, we describe a 51-year-old perimenopausal woman who presented to the emergency department (ED) with vaginal bleeding. A transvaginal POCUS was performed, revealing findings concerning for a molar pregnancy. These findings led to prompt diagnosis and treatment.

BACKGROUND: Twin pregnancies consisting of a complete hydatidiform mole and a coexistent fetus (CMCF) are rare and associated with a high rate of maternal-fetal morbidity and mortality. Management of these pregnancies remains controversial and increasingly challenging following the Dobbs versus Jackson Women\'s Health decision given the viability of the coexisting twin fetus.
METHODS: This case looks at the diagnosis, management, and maternal-fetal outcomes of a viable fetus coexisting molar pregnancy at a large academic center in an abortion-restricted state.
CONCLUSIONS: CMCF pregnancies are associated with a high risk of morbidity and mortality and are increasingly difficult to manage following the Dobbs decision. Testing platforms, which identify genetic abnormalities in the first trimester, are increasingly important as access to abortion care in the United States is restricted.

The hydatidiform mole is a rare gynaecological condition originating from trophoblastic cells, with an incidence of 1-3 per 1000 pregnancies. Theca lutein cysts (TLCs) and an invasive mole are rarely observed in association with a partial mole. This case describes an unusual case involving a 17-year-old primigravida at 11 weeks of gestation. She presented with abdominal pain and was diagnosed with a molar pregnancy with post-evacuation rupture of TLC, presenting as an acute abdomen, subsequently undergoing laparoscopy. Post-molar pregnancies exhibit a highly variable course, ranging from recurrent pregnancy loss and stillbirths to preterm deliveries and recurrent molar pregnancies. Few studies are available on obstetric outcomes after a molar pregnancy; most available data originate from national databases and monocentric research.

BACKGROUND: Chemotherapy is crucial in treating gestational trophoblastic neoplasia (GTN), but its impact on gonadotoxicity is unclear.
METHODS: This case-control study included 57 GTN patients and 19 age-matched patients with molar pregnancies (MP) in 2012-2018. Multiples of the median (MoM) of the serum AMH levels were compared between the two groups, and between patients using single-agent and combination chemotherapy, at baseline, 6, 12, and 24 months after treatment. Their pregnancy outcomes were also compared.
RESULTS: There was no significant difference in the MoM of serum AMH between GTN and MP groups at all time points. Single-agent chemotherapy did not adversely affect the MoM. However, those receiving combination chemotherapy had lower MoM than those receiving single-agent chemotherapy at all time points. The trend of decline from the baseline was marginally significant in patients with combination chemotherapy, but the drop was only significant at 12 months (Z = -2.69, p = 0.007) but not at 24 months (Z = -1.90; p = 0.058). Multivariable analysis revealed that combination chemotherapy did not affect the MoM. There was no significant difference in the 4-year pregnancy rate and the livebirth rate between the single-agent and combination groups who attempting pregnancy, but it took 1 year longer to achieve the first pregnancy in the combination group compared to the single-agent group (2.88 vs. 1.88 years).
CONCLUSIONS: This study showed combination chemotherapy led to a decreasing trend of MoM of serum AMH especially at 12 months after treatment, but the drop became static at 24 months. Although pregnancy is achievable, thorough counseling is still needed in this group especially those wish to achieve pregnancy 1-2 years after treatment or with other risk factors.

A hydatidiform mole (HM), often known as molar pregnancy, is a type of prenatal trophoblastic illness that develops in the placenta and has the potential to spread. HMs are caused by genetic issues with either the egg or the sperm. They are typically discovered in the first trimester of pregnancy. Abnormal bleeding is one of the initial symptoms, which can seldom be accompanied by the passage of hydropic villi. Theca lutein cysts, absent fetal heart tones, enlarged uterus more than anticipated for gestational age, pregnancy-induced hypertension in the first trimester, hyperemesis, and increased levels of human chorionic gonadotropin (HCG) for gestational dates are other characteristic symptoms and signs. A rare type of follicular cyst known as a theca lutein cyst is a benign ovarian disease caused by natural overstimulation of follicles, also known as hyperreactio lutealis (HL). This is linked to choriocarcinomas, multiple gestations, and prenatal trophoblastic illness (molar pregnancy). Unless exacerbated by torsion, rupture, or bleeding, the majority of theca lutein cysts are treated conservatively. Theca lutein cysts do not impact the course of pregnancy and spontaneously recede following delivery. However, HL may mistakenly be diagnosed by doctors as a cancer during pregnancy if it has the potential to look like one. Frequently, inappropriate surgical intervention is caused by the fear of failing to diagnose malignancy. These treatments may therefore result in decreased fertility in the future. Here we present a case of a young unmarried female with an HM and cysts.

Gestational trophoblastic disease comprises hydatidiform mole (HM) (complete or partial) and gestational trophoblastic neoplasia (GTN). Complete and partial moles have different karyotypes, gross and microscopic histopathology, clinical presentation, prognosis, and chances of progress to GTN. Ultrasonography (USG) and human chorionic gonadotropin (hCG) quantification are commonly used to diagnose molar pregnancy and further follow-up until resolution. Our case reports two patients, one with a complete mole and another with a partial mole, who were evaluated and followed up with serial beta hCG as per protocol and were found to have persistent disease and referred for chemotherapy until complete resolution. Fifteen to 20% of the patients with complete moles and about 1-5% of patients with partial moles developed GTN, which is primarily invasive. Hence, proper follow-up and chemotherapy assure 100% curability.

Background Molar pregnancy (MP) incidence and clinical presentation vary significantly worldwide. Recent trends show changes in its clinical representation and incidence, particularly with the adoption of early diagnosis using first-trimester ultrasonography, which has reduced the prevalence of classical second-trimester presentations. This study aimed to analyze the changes in clinical presentation and incidence of MP among the Saudi population over the past 30 years. Methods In this retrospective study at King Fahad University Hospital, 121 complete mole (CM) pregnancy cases diagnosed and pathologically confirmed were reviewed. This included 87 cases from 2007 to 2022 (recent group) and 34 cases from 1992 to 2006 (older group). Cases of CM diagnosed before January 1992 and other diagnoses such as PM, invasive mole, or choriocarcinoma were excluded; thus, this study is focused on CM in particular. We compared patient age, gravidity, parity, abortion history, gestational age at diagnosis, hyperemesis gravidarum symptoms, anemia symptoms, and hemoglobin levels. Classical symptoms and signs related to CM were also reviewed. Data were analyzed using Microsoft Excel 2021 (Microsoft Corporation, Redmond, Washington, United States) and presented as mean, frequency, and percentage, with chi-squared tests for categorical variables; p<0.05 was considered statistically significant. Results The incidence of CM declined from 2.1 per 1,000 deliveries to 0.9 per 1,000 deliveries. Vaginal bleeding was the most common presentation in both the older (91.9%) and recent (67.6%) groups. Hyperemesis gravidarum prevalence was similar in both groups. Theca-lutein cysts were more frequent in the older group (27.5%) than the recent group (8.8%). A significant difference was observed in the occurrence of a large-for-date uterus between the older (63.20%) and recent (23.5%) groups. Notably, 14.7% of patients in the recent group were asymptomatic at diagnosis. Anemia was present in 46 cases (52.8%) of the older group but absent in the recent group, and preeclampsia occurred in 10 cases (11.4%) of the older group but not in the recent group. Conclusions Advancements in ultrasound technology, including transvaginal probes with Doppler capabilities, have enabled earlier pregnancy diagnosis, as early as five to six weeks of gestation. Many MP are now diagnosed in the first trimester without the classic clinical symptoms or \"snow-storm\" ultrasound appearance. The availability of sensitive beta-human chorionic gonadotropin assays has led to the early termination of these pregnancies, marking a significant shift in the management of MP.
