Abstract： 口腔材料引起的过敏反应时有发生,主要为金属和丙烯酸酯类[1],钴过敏较少见,现报道钴铬合金烤瓷冠及钴铬合金根管桩修复后钴过敏1例.1.病例资料:患者,男性,30岁,怀疑钴铬合金烤瓷冠过敏就诊于山东大学校医院口腔科.患者否认系统性疾病病史及药物过敏史.8个月前于外院行右下第二前磨牙钴铬合金根管桩及钴铬合金烤瓷冠修复,自觉患牙无不适症状.冠修复5d后手部出现成簇的粟粒大小水疱,破溃后结痂,双手病损呈对称分布,反复交替出现(图1,2).于当地医院皮肤科诊断为"手癣",给予抗真菌药物局部涂擦1个月余,自觉症状加重,手部溃疡面出现黄白色假膜.6个月前真菌检查结果示,真菌感染阴性.后根据右手无名指活检病理检查结果,诊断为"湿疹状皮炎",给予夫西地酸乳膏局部涂擦,同时服用盐酸非索非那定片,曲安西龙片(维持量),30 d后手部创面基本愈合,患者自行停药.
