189 Atypical Presentation of Endometrial Adenocarcinoma as Non-Puerperal Uterine Inversion in a Young Patient

Introduction/Objective Uterine inversion is a rare condition in which the uterus becomes displaced through the cervix and vagina, sometimes even exiting the body. Non-puerperal uterine inversion can also occur, and is an extremely rare condition, typically associated with uterine tumors and occurs at a mean age of 46 years. Malignant causes, including endometrial carcinoma, are uncommon. Methods/Case Report A 29-year-old woman presented for a routine exam, reporting metrorrhagia and pelvic pain. On exam, a large friable cervical mass was protruding into the vagina. She underwent total hysterectomy. Intraoperatively, complete uterine inversion was identified. Pathologic examination revealed FIGO grade 1 endometrioid adenocarcinoma involving the uterine fundus, lower uterine segment, and superficial cervix. No lymphovascular invasion or extrauterine spread was present. Results NA Conclusion This case illustrates a rare presentation of non-puerperal uterine inversion secondary to endometrioid adenocarcinoma in a young patient. It underscores the importance of considering uterine malignancy in the setting of a cervical mass and atypical vaginal bleeding. This report highlights the critical role of pathology in identifying rare clinical entities and guiding oncologic treatment strategies in gynecologic practice. To date this patient remains disease free.
