Mucinous Borderline Ovarian Tumor with Malignant Transformation: A Case Report and Literature Review

目的：探讨卵巢粘液性交界性肿瘤(mucinous-BOT)恶变的临床病理特征、诊断、治疗及预后，以提高对该疾病的认识和诊治水平。方法：报道1例卵巢粘液性交界性肿瘤恶变的病例，并结合相关文献进行复习。结果：患者为卵巢交界性粘液性肿瘤，囊肿剥除术后复发恶变，预后差。治疗以手术为主，认为保留生育功能的手术应谨慎考虑，完成生育后应考虑行彻底的手术分期。结论：卵巢交界性粘液性肿瘤恶变虽罕见，但预后较差。临床应重视其危险因素，早期诊断和彻底手术是改善预后的关键，术后需密切随访。Objective: To explore the clinicopathological characteristics, diagnosis, treatment, and prognosis of malignant transformation in ovarian mucinous borderline tumors (mucinous-BOTs), aiming to enhance understanding and improve the management of this condition. Methods: A case of malignant transformation in an ovarian mucinous borderline tumor was reported, and a review of relevant literature was conducted. Results: The patient was diagnosed with an ovarian mucinous borderline tumor that recurred and underwent malignant transformation following cystectomy, resulting in a poor prognosis. Treatment primarily involved surgery, and it was concluded that fertility-sparing surgery should be approached with caution. Complete surgical staging should be considered after childbearing. Conclusion: Although malignant transformation in ovarian mucinous borderline tumors is rare, it carries a poor prognosis. Clinical attention should be given to its risk factors, with early diagnosis and thorough surgery being crucial for improving outcomes. Postoperative follow-up is essential.
