We describe an extremely rare case of a borderline tumor arising from an extragonadal giant endometrial cyst. A 41-year-old woman complaining of abdominal pain was referred to our hospital with a diagnosis of large ovarian tumor. Magnetic resonance imaging revealed a large cystic tumor approximately 27 cm × 9 cm in area. The cyst contents were largely removed by suction, and then the tumor was resected laparoscopically. Both adnexa were normal in size and location. The tumor did not originate from the ovaries, and it was adherent only to the bilateral uterosacral ligaments and uterine body. The postoperative histopathological evaluation confirmed the presence of endometrioid borderline tumor with transition from endometriosis. Staging laparotomy was performed, and no remnant tumor was detected. This case is extremely unusual because such a large cystic tumor originating from extragonadal endometriosis is very rare, as is endometrioid borderline tumor arising from endometriosis.
我们描述了一例极为罕见的起源于性腺外巨大子宫内膜囊肿的交界性肿瘤病例。一名41岁主诉腹痛的女性因诊断为巨大卵巢肿瘤被转诊至我院。磁共振成像显示一个面积约为27 cm×9 cm的巨大囊性肿瘤。通过抽吸大量清除了囊肿内容物，然后通过腹腔镜切除了肿瘤。双侧附件的大小和位置均正常。肿瘤并非起源于卵巢，仅与双侧子宫骶韧带和子宫体粘连。术后组织病理学评估证实存在由子宫内膜异位症转变而来的子宫内膜样交界性肿瘤。进行了分期剖腹手术，未检测到残留肿瘤。该病例极为罕见，因为如此大的起源于性腺外子宫内膜异位症的囊性肿瘤非常罕见，起源于子宫内膜异位症的子宫内膜样交界性肿瘤也很罕见。
