INTRODUCTION AND IMPORTANCE: Polypoid endometriosis (PE) is a rare entity, but it is important to recognize because it represents a huge diagnostic challenge due to rarity. On the other hand, it presents as a mass, so it can mimic multiple medical conditions like tumors or abdominal ectopic pregnancy, just like our case.

CASE PRESENTATION: In our case, we present a 16-year-old pregnant woman who was admitted to a rural hospital with amenorrhea and an acute abdomen. Finally diagnosed with PE by accidentally!

CLINICAL DISCUSSION: The patient underwent an emergency surgery under suspicion of an ectopic pregnancy. During the operation, a mass arising from Douglas pouch was found, which was suspected to be an abdominal ectopic pregnancy. The patient was referred to our hospital for further management due to lack of surgical resources. We removed the mass and sent it for histology, which revealed benign PE.

CONCLUSION: Our goal through this case is to shed light on these conditions so that they are not misdiagnosed.
