摘要 目的通过分析几组误诊单发结节的皮肤镜图像及病理特征,从而获取相关鉴别要点,提高诊断的准确性。方法收集近2年皮肤镜误诊的单发结节共18例,重点选取频繁出现的疾病,观察和描述其皮肤镜下表现特征及病理特征,总结鉴别要点。结果误诊疾病间皮肤镜下表现出相似的特征;与结节型基底细胞癌相比,毛发上皮瘤和角化棘皮瘤均有相对较细的血管;小汗腺汗孔瘤表现为血管外周白粉色晕,Spitz痣表现为淡粉色团块与白色相间;与寻常疣相比,脂溢性角化有特征性的蛙卵样结构。结论易误诊疾病在皮肤镜下的图像仍有不同的镜下特点,可辅助临床诊断。 Objective In order to obtain the key points of the dermoscopy images and pathological features of several groups of misdiagnosed solitary dermatoma,so that to analyze the relevant differences and improve the accuracy of diagnosis.Methods Eighty cases of solitary dermatoma misdiagnosed by dermoscopy in the past two years were collected.The frequently misdiagnosed diseases were selected to observe and describe their dermoscopic and pathological features,and the key points of difference were summarized.Results These misdiagnosed diseases showed the similar dermoscopic characteristics.Compared with nodular basal cell carcinoma,both trichoepithelioma and keratoacanthoma have relatively thin blood vessels.Eccrine poroma showed white and pink halo,and Spitz nevus showed pale pink mass with white interphase.Seborrheic keratosis has a characteristic oval-like structure compared with verruca vulgaris.Conclusion These misdiagnosed dieases have different dermoscopic features,which can be used to assist clinical diagnosis.
