Actinic damage of dermal tissues produces several distinct clinical patterns. Three patients are described as having discrete, soft, cordlike bands on the forearms that extend from dorsal areas of actinic damage and senile purpura to greatest prominence in flexural regions with less solar damage. Histochemical analyses and light and electron microscopy studies of the plaques showed changes consistent with solar elastosis. The clinical variants of actinic elastosis and the possible origins of the abnormal elastic fibrils found in the dermis of chronically sun-damaged skin are discussed. Solar elastotic bands are an unusual form of actinic degeneration.
皮肤组织的光化性损伤会产生几种不同的临床模式。描述了三名患者，他们的前臂有离散的、柔软的条索状带，从光化性损伤和老年性紫癜的背部区域延伸至弯曲区域最为突出，而这些弯曲区域受阳光损伤较少。对斑块进行的组织化学分析以及光镜和电镜研究显示出与日光性弹力组织变性一致的变化。讨论了光化性弹力组织变性的临床变体以及在长期受阳光损伤皮肤的真皮中发现的异常弹性纤维的可能来源。日光性弹力组织变性带是光化性退变的一种不寻常形式。
