目的探讨高频彩色多普勒超声对良、恶性皮肤实性肿瘤鉴别诊断的价值。方法收集我院经病理证实的皮肤实性肿瘤患者的资料,分析良、恶性组肿瘤的临床及超声图像特征的差异。结果共512例患者,527个病灶,超声发现率99.43%,定位准确率99.02%;良性及恶性组肿瘤在平均年龄、多发病变比例、分布部位、累及皮肤层次、皮肤层情况、平均最大径线、内部回声、钙化比例、血流情况、后方及周围回声、是否提出病理诊断和定性诊断准确率的差异有统计学意义(P<0.05)。结论高频超声对于皮肤实性肿瘤具有极高的发现率,能准确定位累及皮肤层次,良性及恶性皮肤肿瘤在多项临床及超声表现上有差异。
Objective To investigate the value of high-frequency color Doppler ultrasound in the differential diagnosis of solid tumors of malignant and benign skin. Methods The data of patients with pathologically confirmed solid tumors in our hospital were collected to analyze the clinical and ultrasonographic features of benign and malignant tumors. Results A total of 512 patients and 527 lesions were detected by ultrasound. The detection rate was 99.43% and the localization accuracy was 99.02%. The average age, the proportion of multiple lesions, distribution sites, skin layers, skin layer, , Internal echo, calcification ratio, blood flow, posterior and peripheral echoes, whether the pathological diagnosis and qualitative diagnosis accuracy rate were statistically significant (P <0.05). Conclusion High-frequency ultrasound has a high detection rate for solid tumors of the skin and accurately locates and affects skin layers. There are differences in clinical and ultrasound manifestations between benign and malignant skin tumors.
