Local anesthetics are widely used in clinical practice, and adverse effects are not uncommon. Delayed hypersensitivity reactions are among the most common effects, but immediate-type reactions may also occur. Patch testing should be considered in patients with hypersensitivity reactions. We present a case of allergic contact dermatitis to benzocaine that was detected incidentally by patch testing and highlight the importance of correctly interpreting patch test results when there are concomitant positive reactions.
局部麻醉药在临床实践中广泛应用，不良反应并不罕见。迟发型超敏反应是最常见的反应之一，但速发型反应也可能发生。对于有超敏反应的患者应考虑进行斑贴试验。我们报告一例通过斑贴试验偶然发现的对苯佐卡因的过敏性接触性皮炎病例，并强调当同时出现阳性反应时正确解读斑贴试验结果的重要性。
