diagnosis is very difficult, confusing and challenging. Delay in diagnosis or misdiagnosis is potentially life threatening for mother. Case Report: In this report, a 27-year old woman complaining of abdominal pain and bleeding spotting with 3 weeks delay was referred to hospital. Diagnostic evaluations showed corneal heterotopic pregnancy. Corneal and oviduct was removed and the site was restored. Intrauterine pregnancy was aborted after a few days. Conclusion: Because cornual pregnancies are located at the most richly vascularized area, any rupture can cause heavy bleeding, acute shock and death. So, cornual pregnancies need accurate diagnosis and urgent treatment. Keywords: Pregnancy, Ectopic pregnancy, Heterotopic corneal pregnancy.
