Abstract: Uterine borderline leiomyoma is a group of uterine smooth muscle tumors with special pathological features. Its related pathogenic factors include age, birth history, surgery history, etc. The pathogenesis is not clear, and may be related to sex hormone levels, genetic factors, and abnormal gene expression in the body. Its clinical manifestations are similar to benign uterine fibroids and lack characteristics. The auxiliary examinations before surgery include ultrasound, CT, MRI, etc. The test results lack specificity and are not easy to distinguish from benign uterine fibroids and uterine sarcomas. Preoperative diagnosis is difficult, and the diagnosis mainly depends on postoperative pathological examination. At present, the main treatment method is surgery, and some need adjuvant drug treatment. However, the choice of surgical methods and the effects of drug treatment are still controversial and need further research. Most patients with uterine borderline leiomyoma have a good prognosis, but they are at risk of postoperative recurrence and long-term malignancy. Close follow-up is required after surgery.
