47岁男,平素健康,因全身广泛性大疱疹形成10天入院。大疱开始出现时,患者并无服用任何药物,且病情迅速恶化。几乎整个身体表面均被红斑覆盖。这些斑块表面可见许多直径1cm至5cm的紧张性水疱和松弛性大疱(图A和B),其内充满黄色透明液体。陈旧性皮损边缘可见新发的皮损。胸部和背部皮肤有多处出现剥脱。口腔内可见面积较大的皮损。患者的脸部、双手和双脚均有累及。基于临床表现、皮肤活检(图C,HE染色)和直接免疫荧光法(图D)的结果,我们诊断为线状IgA大疱性皮肤病。该病是一种自身免疫性疾病,以表皮下大疱形成为特征,系自身IgA抗体直接攻击皮下和粘膜下基底膜带抗原所致。患者接受了氨苯砜和全身糖皮质激素治疗,3周后获得临床完全缓解。
