Abstract:
Objective To analyze the very high frequency(VHF)ultrasound features of mixed tumor of the skin(MTS),and to explore the diagnostic value of VHF ultrasound features for MTS.Methods A total of 63 cases of MTS confirmed by surgery and pathology in the Department of Dermatology of Hangzhou Third People's Hospital from January 2019 to March 2024 were selected as observation group,and 63 other benign skin tumors in the same period were used as control group.The VHF ultrasound features of MTS were retrospectively analyzed and summarized,and the diagnostic efficiency of VHF ultrasound features for MTS was evaluated.Results Compared with other benign skin tumors,there were no significant differences in the length diameter,transverse diameter,aspect ratio,presence or absence of calcification,cystic disease,blood flow grade and resistance index between two groups(P＞0.05).However,MTS had a more obvious pseudo-capsule,and most of the internal echoes were not uniform,and the posterior side was accompanied by a enhancing effect,and the blood flow was dominated by marginal blood flow,and the difference between two groups was obvious(P＜0.05).The receiver operating characteristic curve showed that the combination of pseudo capsule,internal echo,marginal flow and peripheral enhancement had the highest diagnostic efficacy,with an area under the curve of 0.772,a sensitivity of 77.8％ ,and a specificity of 71.4％ .Conclusion MTS have specific VHF ultrasound features,which can provide more assistance in the clinical diagnosis of MTS.
