Abstract：
Patch testing is the standard diagnostic test used for patients presenting with symptoms of allergic contact dermatitis. The grading of patch test results classically varies from 1 to 3. The assessment of these results begins with a visual inspection of the presence of erythema, vesiculation, and induration. This leads to a subjectivity in visual evaluation of a patch test. Positive patch testing results can present differently in patients with darker skin tones. A greater variety of images of allergic contact dermatitis in patients with darker skin phototypes can better guide the diagnosis of this condition in skin of color. People with darker phototypes are historically underrepresented in dermatologic images and texts; thus, identifying erythema in darker phototypes may be more difficult for dermatologists, whether or not they were trained in areas of decreased phototype diversity. In this article, we present positive patch testing findings on several different phototypes, with the intention of contributing to images of phototypes underrepresented in dermatology literature.
摘要：
斑贴试验是用于出现过敏性接触性皮炎症状的患者的标准诊断试验。补丁测试结果的等级通常从1到3不等。对这些结果的评估从目视检查红斑的存在开始，囊泡形成,和硬结。这导致在补丁测试的视觉评估中的主观性。阳性斑贴测试结果在肤色较深的患者中可能会有所不同。在皮肤颜色较深的患者中，过敏性接触性皮炎的图像种类更多，可以更好地指导皮肤颜色中这种情况的诊断。历史上，在皮肤病学图像和文本中，具有较深色照片的人代表性不足；因此，对于皮肤科医生来说，在较暗的光型中识别红斑可能更困难，无论他们是否在光型多样性下降的地区接受训练。在这篇文章中,我们对几种不同的光型提出了积极的斑贴测试结果，目的是为皮肤病学文献中代表性不足的光型图像做出贡献。
