Summary We present a 29-year-old non-atopic male apprentice power lineman and recreational cowboy with a case of allergic contact dermatitis due to both occupational and recreational exposure. He presented with a 4-month history of a pruritic, steroid-responsive, intermittent hand, foot and leg dermatitis. Patch testing was positive for chromium, cobalt and a piece of leather from his cowboy boots. His leather work gloves, inner lining of work harness, work boots and cowboy boots were assessed for chromium and cobalt content with handheld fluorescence x-ray spectrometry. Upon replacement of all leather items including the items tested and his leather cowboy saddle, the rash resolved. This case demonstrates the clinical relevance of using a handheld fluorescence x-ray spectrometer to assess for chromium and leather content.

皮革铬钴的手持X射线荧光光谱评价

总结 我们介绍了一名 29 岁的非特应性男性学徒电力线卫和休闲牛仔，他因职业和娱乐接触而患过敏性接触性皮炎。他有 4 个月的瘙痒、类固醇反应性、间歇性手、足和腿皮炎病史。补丁测试对他的牛仔靴上的铬、钴和一块皮革呈阳性反应。他的皮革工作手套、工作安全带内衬、工作靴和牛仔靴采用手持荧光 X 射线光谱仪进行了铬和钴含量评估。在更换所有皮革物品（包括测试物品和他的皮革牛仔马鞍）后，皮疹消退了。该案例展示了使用手持荧光 X 射线光谱仪评估铬和皮革含量的临床相关性。
