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 は、血液が皮膚のより深い層に漏れたときに発生します。皮膚が薄くなり、血管がもろくなった高齢者に、特に日光に多くさらされた場合によく起こります。 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.
