[Heterotopic pregnancy: report of three cases]

The association of intra-uterine and extra-uterine pregnancy has increased steadily with the widespread use of infertility treatment. Diagnosis of extra-uterine pregnancy may be delayed as a result of visualization of an intrauterine gestation sac, leading to a less favorable diagnosis than for simple extrauterine pregnancy. The purpose of this report is to described three heterotopic pregnancies observed in a series of 25 simple extrauterine pregnancies managed in the Gynecology Department of the El Rapha Clinic in Libreville Gabon over an 18 months period. A review of the literature is included to provide more background on this association.
