摘　　要：目的阐述绒毛叶状分割性子宫平滑肌瘤的临床、影像及病理特点。方法报告1例绒毛叶状分割性子宫平滑肌瘤的临床、影像及病理资料。结果患者体检偶然发现盆腔包块,超声:左宫旁低回声包块,范围约77mm×70 mm×50 mm;MRI:宫旁实性肿物,考虑子宫肉瘤可能;病理:左侧宫壁内和宫旁阔韧带、输卵管系膜内多发球茎状肿物;镜下:普通子宫平滑肌瘤广泛黏液变性。术中预诊子宫平滑肌肉瘤,行子宫及左侧附件切除。术后随访10个月无复发。结论绒毛叶状分割性子宫平滑肌瘤是一种罕见的子宫良性平滑肌瘤,因其奇特的形状临床及影像学均易误诊为子宫肉瘤,显微镜下组织学表现为普通子宫平滑肌瘤广泛黏液变性,无恶性肿瘤特点。Objective To explore the clinical imaging and pathological features of cotyledonoid dissecting leiomyoma of the uterus.Method The clinical data of one patient with cotyledonoid dissecting leiomyoma of the uterus was retrospectively analyzed.Results Irregular mass was detected incidentally in a 32-year-old woman with a provisional diagnosis of sarcoma.A multinodular fungating tumor adhering to the left wall of the uterus and extending into the broad ligament was discovered,which was composed of fascicles and nodules of smooth muscle cells with prominent peri-nodular hydropic degeneration.Coagulative necrosis,mitoses and nuclear atypia were absent.The patient underwent total hysterectomy and left salpingo-oophorectomy,no recurrence was found during the follow-up of 20 months.Conclusions Cotyledonoid dissecting leiomyoma of the uterus is a rare benign tumor with a bizarre gross appearance confused with malignant neoplasm.Increasing awareness of the disease can help us to avoid wrong treatment.
