光线性角化病

定义

日光性角化病（AKs）是由长期暴露于紫外线辐射诱发的角质细胞异常增殖和分化的局部区域。白皮肤个体过度暴露于阳光下非常常见。最初为扁平鳞屑性丘疹，由于产生致密的附着性角蛋白，或由于不规则细胞增殖，而从皮肤表面显著升高，从而发展成为原位癌或浸润性鳞状细胞癌。

Actinic keratoses (AKs) are focal areas of abnormal keratinocyte proliferation and differentiation induced by chronic exposure to ultraviolet radiation. They are very common on sun-exposed skin of fair-skinned individuals who have had excessive exposure to sunlight. Initially flat scaly papules, they may become significantly elevated from the skin surface by producing dense adherent keratin or as a result of unregulated cellular proliferation which may progress to frank carcinoma in situ or invasive squamous cell carcinoma.
