Purpose of investigation: To determine the rates of hydatidiform mole (HM) cases at extreme reproductive life in a developing country. Methods: A descriptive study was performed to assess the number of pregnancies and deliveries in Turkey, from 1932 to 2000, based on nationally or internationally published data from different university and state maternity hospitals. Results: A spectrum of prevalence rates in different hospitals were depicted. Almost all of represented data were hospital-based. Percentages of all HM cases < 19 years old and > 40 years old compared to the total number of HMs in each study were not mentioned. In addition, the number of HM compared to total number of deliveries and pregnancies in those age groups were not provided in those studies. Conclusion: There appears to be a need for further descriptive studies on a national basis, in regard to assess total number of HM cases per total pregnancies and deliveries for those age groups.
