To report 2 cases of uterine tumors resembling ovarian sex cord tumors (UTROSCTs) and examine the clinical significance of these tumors found during hysteroscopic endometrial ablation despite benign preoperative endometrial biopsy analysis and imaging suggestive of leiomyoma.
Case report (Canadian Task Force classification III).
Tertiary care hospital.
Two patients with abnormal uterine bleeding.
Hysteroscopic endometrial ablation/resection.
Pathological analysis of intrauterine tissue/lesions obtained by curettage or resection identified 2 unexpected UTROSCTs masquerading as leiomyomas. Following hysterectomy, no residual UTROSCT was identified in the specimens, and both women are well, one at 1 year postsurgery and the other at 3 years postsurgery.
Obtaining additional tissue by routine curettage before endometrial ablation and/or endomyometrial resection, in conjunction with removal of any intrauterine lesions, can identify rare unexpected endometrial lesions not sampled by endometrial biopsy, not detected with ultrasound, and masquerading as leiomyomas during endometrial ablation.
报告 2 例类似于卵巢性索肿瘤的子宫肿瘤（UTROSCT）病例，并探讨尽管术前子宫内膜活检分析和影像学提示为子宫肌瘤，但在宫腔镜子宫内膜消融术中发现这些肿瘤的临床意义。
病例报告（加拿大任务组分类 III）。
三级保健医院。
2 例异常子宫出血患者。
宫腔镜子宫内膜消融/切除术。
刮宫或切除术获得的宫内组织/病变的病理分析确定了 2 例意外的 UTROSCT，表现为子宫肌瘤。子宫切除术后，标本中未发现残留的 UTROSCT，两名女性均恢复良好，1 例术后 1 年，另 1 例术后 3 年。
在子宫内膜消融和/或子宫内膜切除术之前通过常规刮宫获得额外组织，并结合清除任何宫内病变，可以识别子宫内膜活检未取样、超声未检测到、但在子宫内膜消融术中表现为子宫肌瘤的罕见意外子宫内膜病变。
