Solar elastosis (actinic elastosis)
Clinically, solar elastosis presents as yellow, thickened, coarsely wrinkled skin in a photodistribution. Depending on the degree and amount of cumulative sun exposure, the findings can start to be observed in the third decade with gradual progression over the years. Individuals with lighter skin phototypes and a significant history of sun exposure are the highest risk group.
There are many clinical variants of solar elastosis, including cutis rhomboidalis nuchae, Favre-Racouchot syndrome, colloid milium, actinic comedonal plaque, actinic granuloma, elastotic nodules of the ear, arcus senilis, striated beaded lines, keratoelastoidosis marginalis, diffuse elastoma, and elastotic bands.
Solar elastosis is often associated with other signs of photodamage (such as lentigines, poikiloderma, and facial telangiectasias), actinic keratoses, and skin cancers.
