Mature teratomas account for approximately 20% of all ovarian tumors identified in pathological studies. Benign or malignant somatic neoplasms developing within teratomas can arise from any tissue in up to 2% of mature cystic teratomas, including low-grade malignant mucinous neoplasms. This report presents the case of a 34-year-old woman with no previous gynecological or general health issues, who was admitted to our Hospital after an asymptomatic pelvic mass was detected during a routine exam. A transvaginal ultrasound revealed a unilateral pelvic mass in the left adnexal region, measuring 8 cm. The CT scan showed a cystic-appearing formation measuring nearly 12 cm, which indented the bladder dome. Final diagnosis indicated a mucinous carcinoma arising from a mucinous borderline lesion within the context of a mature ovarian teratoma. No other involvement or lymphadenopathies were detected on 18FDG-PET CT scan, and the patient is now well and free of recurrences.
成熟畸胎瘤约占病理研究中所有卵巢肿瘤的20%。在畸胎瘤内发生的良性或恶性体细胞肿瘤，在高达2%的成熟囊性畸胎瘤中可源自任何组织，包括低级别恶性黏液性肿瘤。本报告介绍了一名34岁女性的病例，该女性既往无妇科或全身健康问题，在一次常规检查中发现无症状盆腔肿块后入住我院。经阴道超声显示左侧附件区有一个单侧盆腔肿块，大小为8厘米。CT扫描显示一个近12厘米的囊性结构，压迫膀胱顶部。最终诊断为成熟卵巢畸胎瘤背景下由黏液性交界性病变引起的黏液癌。18FDG-PET CT扫描未发现其他受累情况或淋巴结病变，患者目前情况良好，无复发。
