Phytophotodermatitis (PPD) is a toxic reaction resulting from contact with a photosensitizing botanical chemical followed by exposure to solar or artificial UV light. It may present with bizarre patterns and linear streaks due to a phototoxic agent splashing onto various cutaneous sites; thus, it affects the skin at points of contact and exposure to UV light. Individuals typically experience symptoms within 24 hours of exposure. Children and adolescents seem particularly prone to developing PPD, as they tend to spend time in the sun and also may come into contact with common irritants such as wild parsley in lawn grass or beverages flavored with lime. However, PPD may be more than a recreational dermatitis; it also may represent a serious occupational dermatosis. In any case, the resultant acute dermatitis may be mild or severe with painful bullae and occasionally is more prominently evident as postinflammatory hyperpigmentation.
植物光毒性皮炎（PPD）是一种接触光敏植物化学物质后，再暴露于太阳或人工紫外线而引起的中毒反应。由于光毒性物质溅到不同的皮肤部位，可能会出现奇异的图案和线状条纹；因此，它会影响接触和暴露于紫外线的皮肤部位。个体通常在接触后 24 小时内出现症状。儿童和青少年似乎特别容易患上 PPD，因为他们往往会在阳光下度过时间，也可能会接触到常见的刺激物，如草坪草中的野生欧芹或带有酸橙味的饮料。然而，PPD 可能不仅仅是一种消遣性皮炎；它也可能是一种严重的职业性皮炎。在任何情况下，由此产生的急性皮炎可能是轻度或重度的，伴有疼痛性水疱，偶尔更明显的是炎症后色素沉着过度。
