Textile dye allergy is frequently caused by azo dyes, which can cross-react with structurally similar compounds, including paraphenylenediamine. A case of allergic contact dermatitis to azo textile dyes, presenting principally as a sock dermatitis, is presented. The patient also gave a history of an episode of scalp dermatitis consistent with contact allergy to paraphenylenediamine in hair dye. It is proposed that paraphenylenediamine sensitization from a temporary skin tattoo may have been the primary sensitizing event for these reactions.
纺织品染料过敏通常由偶氮染料引起，偶氮染料可与结构相似的化合物发生交叉反应，包括对苯二胺。本文报告一例对偶氮纺织品染料过敏的接触性皮炎病例，主要表现为袜子性皮炎。患者还曾有过一次头皮性皮炎发作史，符合对染发剂中对苯二胺的接触性过敏。有人提出，来自临时皮肤纹身的对苯二胺致敏可能是这些反应的主要致敏事件。
