Abstract: In this case, the patient had uterine adenocarcinoma with a huge necrotic mass prolapsed from the vagina, complicated by necrotic infection and massive bleeding. Based on ultrasound results preoperatively, uterine prolapse with infected necrosis was considered due to significant vaginal bleeding, prompting emergency surgery and blood transfusion. Postoperatively, pathology review indicated a misdiagnosis. This article aims to analyze the reasons for misdiagnosis through case review and literature review.
