Heterotopic pregnancy is defined as the coexistence of intrauterine pregnancy (IP) and ectopic pregnancy (EP), regardless of its location. It is a type of bi-ovular dizygotic twin pregnancy, its occurrence in a spontaneous cycle is rare. This is a rare and serious pathology which may compromise maternal prognosis. We report two cases of heterotopic pregnancy treated in the Department of Gynecology and Obstetrics I at the University Hospital Hassan II of Fez, over a one-year period. Clinical, ecographic and therapeutic data of this pathology were reported. Pelvic pain was the main reason for consultation. The diagnosis of heterotopic pregnancy was suspected on ultrasound in both cases. The first patient underwent conservative treatment by laparoscopy while the second patient underwent salpingectomy by mini-transverse laparotomy. IP outcome was favorable both cases.
