One case of allergic contact dermatitis caused by polyvinyl chloride identification bands is reported. Patch tests in this case were positive for three of four bands tested, resorcinol monobenzoate, and benzoyl peroxide. Manufacturers could not confirm the presence of resorcinol monobenzoate and benzoyl peroxide in their respective bands. It is concluded that the patient's reaction was allergic and due to an unknown chemical(s) in the bands. Additives may comprise a significant portion of polyvinyl chloride bands. These components may be leachable, and thus lead to contact sensitization with subsequent allergy. Although patch testing is an excellent first step in determining the offending allergen, specialized chemical analysis may be required for exact identification.
报告了1例由聚氯乙烯识别带引起的过敏性接触性皮炎病例。该病例的斑贴试验显示，所测试的4条识别带中的3条、间苯二酚单苯甲酸酯和过氧化苯甲酰呈阳性。制造商无法证实各自识别带中存在间苯二酚单苯甲酸酯和过氧化苯甲酰。结论是，患者的反应是过敏反应，由识别带中一种未知化学物质引起。添加剂可能占聚氯乙烯识别带的很大一部分。这些成分可能会被浸出，从而导致接触致敏并引发后续过敏。尽管斑贴试验是确定致病过敏原的出色第一步，但可能需要进行专门的化学分析才能准确识别。
