皮肤镜在化脓性肉芽肿诊断中的评估

Application value of dermoscopy in the diagnosis of pyogenic granuloma

目的探讨化脓性肉芽肿皮肤镜特征及皮肤镜在化脓性肉芽肿诊断中的应用价值。方法对31例疑似化脓性肉芽肿的31处皮损,先由临床经验丰富的皮肤科医生进行临床诊断,随后由皮肤镜医生进行皮肤镜检查,同时对皮损进行组织病理检查,对比诊断结果。结果31例疑似皮损中,皮肤镜检查确诊25例,组织病理检查确诊27例。以组织病理检查为金标准,皮肤镜检查的灵敏度为93%,特异度为75%。化脓性肉芽肿患者的皮肤镜特征以红色均质区最多见(25/27,93%),其次为白色领圈样结构(18/27,67%)。常见皮肤镜模式为红色均质区+白色领圈样结构+白色条带(7/27),其次为红色均质区+白色领圈样结构(6/27)、红色均质区+白色领圈样结构+血管结构(4/27)。结论皮肤镜可以作为化脓性肉芽肿的辅助检查和诊断方法。

Objective To evaluate the dermatoscopic features of pyogenic granuloma and the application value of dermatoscopy in the diagnosis of pyogenic granuloma.Methods 31 suspected pyogenic granuloma lesions from 31 patients were first clinically diagnosed by experienced dermatologists,followed by dermatoscopic and histopathological examinations of the lesions,with a comparison of the diagnostic results.Results Among the 31 suspected lesions,dermatoscopy diagnosed 25 cases,while histopathological examination confirmed 27 cases.With histopathological results as the reference standard,the dermatoscopy exhibited a sensitivity of 93%and specificity of 75%.The dermatoscopic features of pyogenic granuloma were most commonly red homogeneous areas(25/27,93%),followed by white collar-like structures(18/27,67%).The common dermatoscopic patterns were red homogeneous areas+white collar-like structures+white band(7/27),followed by red homogeneous areas+white collar-like structures(6/27),and red homogeneous areas+white collar-like structure+vascular structure(4/27).Conclusion The dermoscopy is a valuable tool for the diagnosis of pyogenic granuloma.
