An atypical presentation of Retain Product of Conception in the Cervix

Background: Retained product of conception (RPOC) occurs when fragments of the placenta or decidual tissues are retained in the uterus, often leading to postpartum hemorrhage. Early and accurate diagnosis, aided by ultrasonography, is essential for appropriate management and prevention of complications. Case presentation: We reported a case of a 22 years old woman admitted to our tertiary medical department with irregular vaginal bleeding and abdominal pain and no past medical history. Her abdominal ultrasonography revealed a normal-sized uterus and homogenous myometrial echogenicity. an heterogenous echogenic mass containing considerable vascularity and feeding vessels from the endometrial cavity was observed in the cervix. Additionally, the patient’s beta human chorionic gonadotrophin (Beta-HCG) concentration was positive despite her claiming to be a virgin. Subsequently, the patient underwent hysteroscopy, and the infected and malodorous lesion was removed from the uterus with the diagnosis of RPOC. In the follow up she had no complications. Conclusion: Assuming the expected location of RPOC, which is in the endometrial cavity, no case of RPOC in the cervix has been reported heretofore. The purpose of this study is to report our experience in considering the differential diagnosis of RPOC as a cervical lesions and the importance of ultrasonography in early pregnancy.
