OBJECTIVE
To describe a rare extrauterine mass of an unknown origin that was composed of smooth muscle with a central cavity lined by endometrium, which resembled a uterus.
DESIGN
Case report.
SETTING
Academic teaching hospital.
PATIENT(S): A 17-year-old girl with severe dysmenorrhea was found to have a uterus-like mass composed of smooth muscle and lined by endometrium in the left broad ligament.
INTERVENTION(S): Abdominal surgery.
RESULT(S): The mass was successfully removed surgically, and her dysmenorrhea resolved. Histopathological examination revealed that the uterus-like mass was composed of smooth muscle with a cavity lined by endometrial glands and stroma.
CONCLUSION(S): The histogenesis of a uterus-like mass is theorized to be a Müllerian system anomaly, metaplastic change, and/or heterotopia. We believe metaplasia is the most likely cause in this case. Alhough rare, it should be considered in the differential diagnosis of dysmenorrhea of uncertain etiology.
目的
描述一种罕见的、起源不明的子宫外肿块，其由平滑肌组成，中央有腔，内衬子宫内膜，类似于子宫。
方法
病例报告。
地点
学术教学医院。
患者
一名 17 岁女孩，因严重痛经，在左侧阔韧带中发现一个由平滑肌组成、内衬子宫内膜的类似子宫的肿块。
干预
腹部手术。
结果
肿块成功地通过手术切除，她的痛经得到缓解。组织病理学检查显示，类似子宫的肿块由平滑肌组成，中央有腔，内衬子宫内膜腺体和基质。
结论
类似子宫的肿块的组织发生理论上被认为是米勒管系统异常、化生改变和/或异位。我们认为在这种情况下，化生最有可能是原因。虽然罕见，但在不明原因痛经的鉴别诊断中应考虑到这一点。
