A 62-year-old man, with a 20-year history of seborrhoeic dermatitis, presented with a worsening of his dermatitis. He had previously been demonstrated to be allergic to various topical corticosteroids, so he had been using an emollient cream (Sebclair), containing piroctone olamine and various anti-inflammatory substances, for 6 months, with good effect. Patch testing to the cream and its ingredients revealed positive reactions to both propyl gallate and pentylene glycol. A positive reaction to propylene glycol was also detected, whereas patch testing to butylene glycol was negative. Complete remission followed avoidance of the offending substances.
一位 62 岁男性，脂溢性皮炎病史 20 年，此次因皮炎加重就诊。此前，他被证实对各种外用皮质类固醇过敏，因此使用含有吡罗克酮乙醇胺和各种抗炎物质的保湿霜（Sebclair）已有 6 个月，效果良好。对该乳膏及其成分进行斑贴试验显示对没食子酸丙酯和戊二醇均呈阳性反应。还检测到对丙二醇的阳性反应，而对丁二醇的斑贴试验呈阴性。避免接触致敏物质后皮损完全消退。
