    "abstract": "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.",
