子宫内膜间质肿瘤27例临床病理分析
【摘要】 目的:探讨子宫内膜间质肿瘤的临床、病理及免疫组化特征。方法:收集2007年3月-2016年3月笔者所在医院收治的27例子宫内膜间质肿瘤的临床及病理资料。结果:27例子宫内膜间质肿瘤患者中子宫内膜间质结节4例、低度恶性子宫内膜间质肉瘤17例,高度恶性子宫内膜间质肉瘤3例,未分化子宫肉瘤3例。免疫组化结果示CD10、PR在子宫内膜间质结节、低度恶性子宫内膜间质肉瘤、高度恶性子宫内膜间质肉瘤、未分化子宫肉瘤中表达逐渐减弱,而Ki-67则逐渐增强。结论:子宫内膜间质肿瘤组织病理形态多样,可伴多成分分化,易被误诊或漏诊,细致的观察、免疫组化等有助于诊断。

【Abstract】 Objective:To investigate the clinical features,clinicopathology,immunohistochemistry of endometrial stromal tumors.Method:A retrospective analysis of clinical data was conducted in 27 patients with endometrial stromal tumors who were admitted in our hospital from March 2007 to March 2016.Result:There were 4 cases of endometrial stromal nodule,17 cases of low grade endometrial stromal sarcoma,3 cases of high grade endometrial stromal sarcoma,3 cases of undifferentiated uterine sarcoma.Immunohistochemical results of CD10 and PR in endometrial stromal nodule,low grade endometrial stromal sarcoma,high grade endometrial stromal sarcoma,undifferentiated uterine sarcoma were gradually decreased,but Ki-67 gradually increased.Conclusion:Endometrial stromal tumors are various in pathological morphology,can be associated with multiple components differentiation,easy to be misdiagnosed or missed diagnosis,careful observation and immunohistochemistry can be helpful in diagnosis.

子宫内膜间质肿瘤(endometrial stromal tumours)由类似正常增生期子宫内膜间质的肿瘤细胞组成,来源于原始多潜能性间质细胞。子宫内膜间质肉瘤(endometrial stromal sarcoma,ESS)是一种罕见恶性肿瘤,年发病率1/100万~2/100万,约占全部子宫恶性肿瘤的0.2%,占子宫肉瘤的10%~15%[1],良性的子宫内膜间质结节(Endometrial stromal nodule, ESN)发病率更低。子宫内膜间质肿瘤病理形态多样,易被误诊或漏诊,本研究收集笔者所在医院27例子宫内膜间质肿瘤患者,对其临床、病理诊断及鉴别诊断、免疫组化特征进行分析及探讨。
