A 42-year-old woman acquired solar urticaria approximately ten minutes after exposure to sunlight. Urticaria developed from visible light emitted from a projector lamp after a similar time lag. Monochromatic rays between 400 and 500 nm induced immediate urticaria by irradiation, with four times the minimal urticarial dose. Urticaria that was induced by monochromatic rays of the projector lamp was completely inhibited by immediate reirradiation of test sites with light waves longer that 530 nm. Radiant heat exposure from an electric hair dryer at 50 degrees C had no suppressive effects on the development of urticarial lesions.
一名42岁女性在暴露于阳光后约十分钟患上日光性荨麻疹。在类似的时间间隔后，投影仪灯发出的可见光也引发了荨麻疹。400至500纳米之间的单色光线照射可诱发即刻性荨麻疹，其最低荨麻疹剂量为四倍。用波长大于530纳米的光波立即再次照射测试部位，可完全抑制投影仪灯单色光线诱发的荨麻疹。50摄氏度的电吹风辐射热暴露对荨麻疹皮损的发展没有抑制作用。
