Changing Trends in the Clinical Presentation and Incidence of Molar Pregnancy in Saudi Arabia: A 30-Year Retrospective Analysis.

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.
