Introduction: Heterotopic pregnancy is a rare event. This type of pregnancy includes  simultaneous intrauterine pregnancy and ectopic pregnancy. Because of the high risk of rupture of ectopic pregnancy in this case, the diagnosis of this life-threatening condition is most important. So, this study was performed with aim to introduce a case of heterotopic pregnancy.
Case report: In this article, a 20 years old pregnant woman at 18 weeks of pregnancy with clinical symptoms of pelvic mass with a presumptive diagnosis of malignant ovarian tumor is introduced. Surgical report of the frozen section of pelvic mass detected ectopic pregnancy and after surgery, intrauterine pregnancy continued until the delivery of a healthy baby.
Conclusion: Although heterotopic pregnancy is a rare event, but we should consider the risk of heterotopic pregnancy in all pregnant women. Heterotopic pregnancy in case of lack of attention and inappropriate treatment can lead to emergency and critical situation.
