Although phototoxic reactions to plants are common, photoallergic contact dermatitis to plants and plant products rarely occurs. Our objective was to review the importance of including diallyl disulfide in the evaluation of patients with suspected photosensitivity. Phototests for ultraviolet B, ultraviolet A, and visible light as well as patch tests and photopatch tests for 49 allergens from the New York University Skin and Cancer Unit Photopatch Test Series were performed. Three patients had positive photopatch-test results to diallyl disulfide, which is the allergen in garlic. The authors conclude that although photocontact allergy to diallyl disulfide is rare, this allergen should be included in photopatch-test series.
尽管对植物的光毒性反应很常见，但对植物及植物产品的光变应性接触性皮炎却很少发生。我们的目的是评估在疑似光敏性患者的评估中纳入二烯丙基二硫的重要性。我们进行了紫外线B、紫外线A和可见光的光试验，以及对纽约大学皮肤与癌症中心光斑贴试验系列中的49种变应原进行斑贴试验和光斑贴试验。三名患者对二烯丙基二硫（大蒜中的变应原）的光斑贴试验结果呈阳性。作者得出结论，尽管对二烯丙基二硫的光接触过敏很少见，但该变应原应纳入光斑贴试验系列中。
