Solar purpura ("Senile purpura") is a skin condition characterized by large, sharply outlined, 1- to 5-cm, dark purplish-red ecchymoses appearing on the dorsa of the forearms and less often the hands. It is caused by sun-induced damage to the connective tissue of the skin.

Actinic purpura 是指血液渗入皮肤深层时发生的情况。这种情况更常见于皮肤变薄、血管脆弱的老年人,尤其是经常暴露在阳光下的人。 Actinic purpura results from the extravasation of blood into the dermis. This phenomenon is due to the skin atrophy and fragility of the blood vessels in elderly individuals, which is exacerbated by chronic sun exposure.
