Abstract：
The concurrent presentation of a low-grade appendiceal mucinous neoplasm (LAMN) and a borderline Brenner tumor (BT) of the ovary are exceedingly rare. Brenner tumors stand out as a particularly uncommon form, making up only around 5% of all benign epithelial tumors of the ovary. Among the ovarian Brenner, the borderline subtype is even rarer. Appendiceal neoplasm (LAMN) and right ovarian BT cannot be distinguished due to their anatomical position. LAMN is often an incidental finding and at later stages when left undiagnosed may lead to pseudomyxoma peritonei (PMP). This case describes a postmenopausal woman in her 50s experiencing abdominal pain and bloating for a week. Elevated carcinoembryonic antigen (CEA) levels and imaging suggested a potential right ovarian tumor. Interestingly, it revealed a unique combination of borderline Brenner tumor of the right ovary and low-grade appendiceal mucinous neoplasm.
摘要：
同时出现低级别阑尾黏液性肿瘤（LAMN）和卵巢交界性布伦纳肿瘤（BT）极为罕见。布伦纳肿瘤是一种特别罕见的形式，仅占所有卵巢良性上皮性肿瘤的5%左右。在卵巢布伦纳中，边缘亚型甚至更罕见。阑尾肿瘤（LAMN）和右卵巢BT由于其解剖位置而无法区分。LAMN通常是偶然发现，在后期未确诊时可能会导致腹膜假性黏液瘤（PMP）。该病例描述了一名50多岁的绝经后妇女经历了一周的腹痛和腹胀。升高的癌胚抗原（CEA）水平和影像学提示潜在的右卵巢肿瘤。有趣的是,它揭示了右卵巢交界性Brenner肿瘤和低级别阑尾黏液性肿瘤的独特组合。
