An Unusual Case of Rising Serum βhCG in the Setting of Retained Products of Conception: A Case Report

Retained products of conception (RPOC) is defined by persistent trophoblastic tissue inside the uterine cavity. This can be present after a vaginal or cesarean birth, miscarriage, or termination. Patients with RPOC often present with abnormal or persistent bleeding per vagina, abnormal vaginal discharge, or pain. The presence of RPOC can be associated with a positive serum beta human chorionic gonadotropin hormone (βhCG), which is expected to remain stagnant until resolution of the RPOC. This case report outlines a presentation wherein an inappropriately rising βhCG was found to be attributed to RPOC. This diagnosis was confirmed by histopathology collected during surgical management.
