We report a case of contact dermatitis of the ear canal due to rubber earplugs. A 31-year-old Japanese woman had a 2-year history of eczema confined to her ears. Applications of various topical steroids had shown no beneficial effect upon her lesions. Considering contact dermatitis as a possible diagnosis we performed patch tests. Positive eczematous patch test results were obtained with mercaptobenzothiazole, tetramethylthiuram disulfide and her rubber earplugs, which she had used whenever she took a bath. The eruption cleared after the patient stopped using the rubber earplugs.
我们报告一例因橡胶耳塞导致的外耳道接触性皮炎病例。一名31岁的日本女性有两年局限于耳部的湿疹病史。使用各种外用类固醇对其皮损均无有益效果。考虑到接触性皮炎可能是诊断结果，我们进行了斑贴试验。巯基苯并噻唑、二硫化四甲基秋兰姆以及她每次洗澡时使用的橡胶耳塞斑贴试验结果呈湿疹阳性。患者停止使用橡胶耳塞后皮疹消退。
