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 የሚከሰተው ደም ወደ ቆዳው ጥልቅ ሽፋን ሲገባ ነው። ብዙ ጊዜ ይህ በቆዳው እየሳሳ እና ደካማ የደም ቧንቧዎች ባለች አረጋውያን ላይ ተከስቷል፣ በተለይም ብዙ የፀሐይ መጋለጥ ካጋጠሙት ይኖራል። 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.
