7. Connective Tissue Damage Induced by the Sun
• Sun-induced damage to the connective tissue of the dermis may result in solar purpura, particularly in older white men and women.
• The patches and macules of solar purpura usually are purple and irregularly shaped. They often occur on a background of dermatoheliosis (lichenification, stellate white pseudoscars, and sallow skin color).
• The lesions usually are found on the extensor surfaces of the forearms and the dorsa of the hands at sites of minor trauma and may occur on the neck. They typically resolve over 1 to 3 weeks.
