Lidocaine is one of the most widely used local anesthetics. It can be administered topically or parenterally. Allergic contact dermatitis from lidocaine is uncommon, but an increasing number of cases have been reported in recent years. We present the case of a 66-year-old man who presented with acute dermatitis on the pinna and left cheek after applying ear drops. Patch tests were positive for the product itself and for lidocaine in the ear drops, thereby confirming the diagnosis of contact dermatitis from lidocaine.
利多卡因是使用最广泛的局部麻醉剂之一。它可以局部给药或胃肠外给药。利多卡因引起的过敏性接触性皮炎并不常见，但近年来报告的病例越来越多。我们报告一例66岁男性，在滴耳后耳廓和左脸颊出现急性皮炎。斑贴试验显示该产品本身以及滴耳液中的利多卡因呈阳性，从而确诊为利多卡因引起的接触性皮炎。
