【摘要】 目的探讨慢性光线性皮炎(CAD)的临床特点及作用光谱。方法回顾性分析20例CAD患者临床资料及光试验结果。结果20例CAD患者,男女之比为5.67∶1;中位年龄61岁;集中于春夏季发病,50%的发病或加重与日晒有关;皮损主要发生于暴露部位,表现为红斑、丘疹、浸润肥厚性斑块;病理示慢性湿疹样皮炎。光试验:16例患者长波紫外线最小红斑量(UVA-MED)降低,范围6.46~35.98 J/cm2;10例患者中波紫外线最小红斑量(UVB-MED)降低,范围9~53.48 mJ/cm2;8例患者单一UVA-MED降低,2例患者单一UVB-MED降低。结论光试验是诊断CAD的主要依据,CAD的作用光谱有待于更大样本量的研究。更多还原

【Abstract】 Objective To study the clinical feature and spectral range of ultraviolet in chronic actinic dermatitis(CAD).Methods Clinical data of 20 cases with chronic actinic dermatitis were analysed retrospectively.Rusults The male:female ratio was 5.67:1.The average age of onset was 61 years.The onset often took place in spring and summer.50% of the cases were found with a light exacerbating history.Lesions were distributed primarly on the exposed skin and included erythema,populs and thicked plaques.Pathologic histology showed chronic eczematoid dermatitis.A lower UVA-MED was found in 80% of the cases,ranging from 6.46 J/cm2 to 35 J/cm2.While a lower UVB-MED in 50%,ranging from 9 mJ/cm2 to 53.48mJ/cm2.40% were found to be sensitive to UVA alone,and 10% UVB alone.Conclusions Diagnosis of chronic actinic dermatitis depends mainly on Results of photobiological test.The action spectrum is expected to be studied in a larger sample.更多还原
