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 កើតឡើងនៅពេលឈាមហូរចូលទៅក្នុងស្រទាប់ជ្រៅនៃស្បែក។ វាកើតឡើងជាញឹកញាប់ចំពោះមនុស្សវ័យចំណាស់ដែលមានស្បែកស្តើង និងសរសៃឈាមផុយស្រាយ ជាពិសេសបើពួកគេត្រូវពន្លឺព្រោះអាទិត្យច្រេន។ 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.
