Abstract

Heterotopic pregnancy with interstitial pregnancy is a rare condition with fatal consequences if diagnosis is delayed. Hence, previous reports have focused on criteria and tools that can expedite obstetricians’ diagnosis. While early diagnosis is important, other differentials should also be kept in mind. Herein, we report a case of a patient who underwent resectoscopy and diagnostic laparoscopy with cornual mass resection under the diagnosis of heterotopic pregnancy (missed abortion of intrauterine pregnancy with interstitial pregnancy). Histopathologic examination revealed that suspected interstitial mass was leiomyoma that underwent cystic change. We hope this case will emphasize the importance of considering benign uterine mass with cystic formation for differential diagnosis of interstitial pregnancy
