光泽苔藓的反射式共聚焦显微镜图像特征

摘要

Objective:To determine the characteristics of lichen nitidus under reflectance confocal micros-copy ( RCM) . Methods:The lesions of 30 patients ( typical lesions in 18 patients, atypical lesions in 12 pa-tients) who were preliminarily diagnosed as lichen nitidus were observed under RCM. The lesions in twelve pa-tients were atypical, which were taken histological examination. Results:The characteristics of the 30 patients under RCM were enlargement of some annular dermal papillas, melanophages with strong light refraction and various inflammatory cells with mild or weak light refraction, thin epidermal layer, obscure boundary between epidermis and dermis. The characteristics of lichen nitidus under RCM were similar to the pictures in histopa-thology. Conclusion:The anatomical structure of lichen nitidus can be observed under RCM, which helps for the diagnosis of lichen nitidus.%目的：：明确光泽苔藓的反射式共聚焦显微镜( RCM)图像的特征。方法：选择临床拟诊为光泽苔藓的患者30例(18例具有典型皮疹,12例皮损不典型),对其皮损进行RCM检测并对其中12例不典型患者行组织病理学检查以进一步明确诊断。结果：30例RCM均可见真皮乳头环扩大,其内见高折光单一核炎细胞及噬色素细胞浸润；扩大的真皮乳头处表皮层变薄,真、表皮交界不清。图像特征与光泽苔藓病理改变一致。结论：反射式共聚显微镜检查能反应出光泽苔藓患者病变皮损的微解剖结构,能为光泽苔藓的诊断提供有力的客观依据。
