Abstract

We report a patient with contact stomatitis due to combined sensitization to palladium and platinum. Patch testing showed strong and persistent allergic patch test reactions to palladium chloride (1% pet.), ammonium tetrachloroplatinate (0.25% pet.), and a palladium metal plate. A platinum metal plate showed a weaker reaction. Histological examination of a biopsy from the test site of palladium chloride (1% pet.) at D3 showed both eczematous and lichenoid changes.

摘要

我们报告了一名因对钯和铂联合致敏而患接触性口炎的患者。斑贴试验显示，对氯化钯（1% 凡士林）、氯铂酸铵（0.25% 凡士林）和一块钯金属板有强烈且持续的过敏性斑贴试验反应。一块铂金属板的反应较弱。在第3天对氯化钯（1% 凡士林）试验部位的活检组织进行组织学检查，显示有湿疹样和苔藓样改变。
