Abstract：Objective To explore the clinical characteristics,key points of differential diagnosis,causes of misdiagnosis and preventive measures of endometrial polyps(EP).Methods The clinical data of 10 patients with EP misdiagnosed as endometrial hyperplasia(EH)admitted from December 2021 to September 2024 were retrospectively analyzed.Results The patients in this group mainly presented with irregular vaginal bleeding and menstrual disorders for 3 to 4 months.Their vital signs were stable,and no abnormalities were found during gynecological physical examinations.Transvaginal ultrasound shows uneven thickening of the endometrium,hyperechoic space-occupying lesions in the uterine cavity accompanied by punctate or strip-like blood flow signals.The initial diagnosis was EH.After being treated with the levonorgestrel intrauterine contraceptive system,the effect was not satisfactory.The patient was later diagnosed with EP through hysteroscopy and endoscopic biopsy.The misdiagnosis period was 2 to 3 months.All the patients in this group were treated with hysteroscopic electroresection after diagnosis.The general condition of the patients after the operation was good.At 6-month follow-up,the patient's condition improved and there was no recurrence.Conclusion EP in women are more likely to be misdiagnosed as EH.Clinicians should enhance their understanding of atypical images of EP,conduct relevant examinations for patients at appropriate time in combination with their medical history,and perform hysteroscopy and endoscopic biopsy when necessary to reduce the rate of misdiagnosis.
