慢性湿疹和接触性皮炎在反射式共聚焦显微镜(皮肤三维CT)中的影像学特征研究

摘要

Objective:To describe and summarize the imaging images of chronic eczema and contact dermatitis by reflectance confocal microscopy(RCM).Methods:42 chronic eczema cases and 25 contact dermatitis cases were examined by RCM.Chronic eczema patients must be performed by histopathological examination.Using x^2 test for some skin RCM image characteristics were analyzed.Results:1.1RCM mainly showed corneous layer thickening,hyperkeratosis,spinous layer thickening,epidermal prominence was significantly longer,dermal layer telangiectasia,inflammation of small blood vessels around the cell infiltration in 42 cases of chronic eczema;1.2 RCM mainly showed epidermal cell and(or)intracellular edema,may haue spinous layer formation and(or)corner layer under blister,dilated vessels in the dermal papilla in 25 cases of contact dermatitis.Conclusion:Chronic eczema and contact dermatitis showed different RCM features.This result will provide the diagnosis clues for clinicians.%目的:对慢性湿疹和接触性皮炎在皮肤三维CT中的影像学图像进行描述及总结.方法:对临床诊断为慢性湿疹的42名患者和接触性皮炎的25名患者行皮肤三维CT检测.同时慢性湿疹患者进行组织病理检查,明确临床诊断.并用卡方检验对某些皮肤三维CT图像特征进行分析.结果:1.1慢性湿疹皮肤三维CT主要表现为角质层增厚,角化过度,棘层增厚,表皮突显著延长,真皮浅层毛细血管扩张,小血管周围常有炎性细胞浸润,呈慢性非特异性炎症改变;1.2接触性皮炎皮肤三维CT主要表现为表皮细胞间和(或)细胞内水肿,可有棘层内和(或)角层下水疱形成,真皮乳头血管扩张.结论:慢性湿疹和接触性皮炎患者皮肤三维CT影像学特征各有其特异性表现,可为临床医师提供诊断和鉴别诊断方面的依据.
