简介：目的研究抗FcεRⅠα自身抗体在慢性自发性荨麻疹（Chronicspontaneousurticaria,CSU）中的表达及临床意义。方法采用酶联免疫吸附法（ELISA）检测CSU患者中抗FcεRⅠα自身抗体的表达,并分析抗FcεRⅠα自身抗体与CSU患者的病程、荨麻疹活动性评分（UAS）评分、风团数目、瘙痒程度、生活质量评分、单一抗组胺药疗效的临床相关性。结果CSU患者组抗FcεRⅠα抗体水平较正常对照组明显升高（P〈0.05）,抗FcεRⅠα抗体水平与病程、荨麻疹活动性评分（Urticariaactivityscore,UAS）、风团数目评分、瘙痒程度评分、生活质量评分无明显相关性（P〉0.05）,单一抗组胺药使用有效者其血清抗FcεRⅠα抗体滴度低于单一抗组胺药治疗无效者（P〈0.05）。结论抗FcεRⅠα抗体在CSU发病中有重要的作用,抗FcεRⅠα抗体滴度较高的CSU患者可能对常规抗组胺药治疗抵抗。

简介：乳房外Paget病（EMPD）是一种罕见的，发生于乳房外的一种表皮内存在Paget细胞的湿疹样癌。可发生于外阴、阴囊、腹股沟、阴茎、肛周等大汗腺丰富的部位，常常与表皮内肿瘤和内脏肿瘤有关，由于表现多种多样易出现误诊。在病理上应与Bowen病，浅表型恶性黑色素瘤区别，发生于外阴的乳房外Paget病在临床上更易误诊为湿疹，脂溢性皮炎。本文介绍了2例被误诊的Paget病，同时复习了国内外有关本病的一些诊断和治疗方面的进展。
