摘　　要：目的:探讨小汗腺螺旋腺瘤(eccrine spiradenoma,ES)的超声特征,评估超声诊断效能。方法:选取2011年10月至2021年10月3所三级甲等医院经病理证实为ES的19例患者(24个病灶)作为研究组,另选取同期经病理证实的常见自发性疼痛及触痛的46例患者(46个软组织肿块)作为对照组。分析两组病变的声像图征象,包括解剖层次、形态、边界、内部回声、回声分布、钙化、后方回声、血流分级等,比较两组病变的声像图征象差异。采用多因素Logistic回归分析筛选ES的危险声像图征象;以手术病理结果作为金标准,计算危险声像图征象诊断ES的敏感性、特异性。结果:两组病变的分叶状形态、边界、内部回声及后方回声声像特征差异有统计学意义(χ^(2)=32.65、15.65、5.77、13.63,均P<0.01)。多因素Logistic回归模型分析显示,分叶状形态、后方回声增强是ES的危险声像特征。分叶状形态诊断ES的敏感性和特异性为79.17%、89.13%,后方回声增强诊断ES的敏感性和特异性为95.83%、47.83%;分叶状形态+后方回声增强征象组合诊断ES的敏感性和特异性为79.17%、97.83%。结论:分叶状形态、后方回声增强是ES重要的超声特征,具有较高的超声诊断效能。Objective To investigate the ultrasonic characteristics of eccrine spiradenoma(ES)and to analyze the diagnostic value.Methods Nineteen ES patients with 24 lesions confirmed by pathology in 3 grade-A tertiary hospitals from October 2011 to October 2021 were enrolled as study group,and in the same time,46 patients with 46 masses in the skin and muscular tissues with clinical features of automatic pain and/or tenderness were selected as control group.The ultrasonographic characteristics of the two groups were analyzed retrospectively,including anatomical location,shape,boundary,internal echogenicity,echogenic distribution,calcification,posterior acoustic effect,and vascularity.The ultrasonographic characteristics of the two groups were compared,and the risk sonographic characteristics of ES were obtained by multivariate logistic regression analysis.The sensitivity and specificity of ultrasound characteristics for the diagnosis of ES were calculated.Results The ultrasonic characteristics of the two groups had significant differences in lobulated shape,boundary,internal echogenicity and posterior acoustic effect(χ^(2)=32.65,15.65,5.77,13.63;all P<0.01).Multivariate logistic regression analysis showed that lobulated shape and posterior acoustic enhancement were the risk ultrasonic characteristics of ES.The sensitivity and specificity of lobulated shape and posterior acoustic enhancement characteristics in the diagnosis of ES were 79.17%,89.13%,95.83%and 47.83%,respectively;and the sensitivity and specificity of the combination of lobulated shape and posterior acoustic enhancement characteristics in the diagnosis of ES were 79.17%and 97.83%,respectively.Conclusions The lobulated shape and posterior acoustic enhancement characteristics are important for the identification of ES,which have higher diagnostic efficacy for ES.
