Abstract:
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.
