CASE REPORT
A 57‐year‐old white nonatopic man was referred for evaluation of a chronic face rash. He would develop itchy, oozing, crusted red plaques, and patches on the face where his continuous positive airway pressure (CPAP) mask would rest (Swift FX; Resmed, Australia; Figure 1A). He routinely cleaned the mask with dilute vinegar only. He had similar reactions from the frame of his plastic reading glasses.
Patch testing was performed in the typical fashion.1 The patient was tested to a standard, supplemental, rubber, plastic/glue, and acrylate series. In addition, he was tested to shavings of the plastic frame from his eyeglasses and a piece of his silicone CPAP mask. To reduce in‐person clinic exposure amidst the ongoing SARS‐CoV‐2 (severe acute respiratory syndrome coronavirus 2) pandemic, the assessment was limited to a single delayed reading performed at day 5. Positive reactions were seen to his silicone CPAP mask (++, Figure 1B) and to his reading glasses (++, Figure 1C). Additional positive reactions were to linalool (+), drometrizole (+), and 2‐hydroxyethyl methacrylate (+). All other patch tests were negative.
The patient was counselled to wear only metal eyeglasses. The mask manufacturer denied that any of the chemicals found on patch testing were present in the CPAP mask. Manufacturer information for the glasses was not available. The patient declined further investigation of his reactions with patch testing as he found an alternative mask that did not cause a reaction.

持续气道正压面罩对硅胶过敏性接触性皮炎
案例报告
一名 57 岁的非过敏性白人男性被转诊评估慢性面部皮疹。他会在脸上长出发痒、渗出、结痂的红色斑块,并在他的持续气道正压通气 (CPAP) 面罩放置的地方出现斑块(Swift FX;Resmed,澳大利亚;图 1A)。他经常只用稀醋清洁面膜。他对塑料老花镜的镜框也有类似的反应。
补丁测试以典型的方式进行。1对患者进行了标准、补充、橡胶、塑料/胶水和丙烯酸酯系列测试。此外,他还接受了眼镜塑料镜框碎屑和一块硅胶 CPAP 面罩的测试。在持续的 SARS-CoV-2(严重急性呼吸系统综合症冠状病毒 2)大流行期间,为了减少面对面的诊所暴露,评估仅限于在第 5 天进行的一次延迟读数。对他的硅胶 CPAP 面罩(+ +,图 1B)和他的老花镜(++,图 1C)。其他阳性反应是芳樟醇 (+)、屈美唑 (+) 和甲基丙烯酸 2-羟乙酯 (+)。所有其他斑贴试验均为阴性。
建议患者只戴金属眼镜。面罩制造商否认在贴片测试中发现的任何化学物质存在于 CPAP 面罩中。眼镜的制造商信息不可用。患者拒绝通过贴片测试进一步调查他的反应,因为他发现了一种不会引起反应的替代面罩。
