title: [A woman with red-purple blotches].
abstract: A 56-year-old woman presented with red-purple blotches on both forearms which had suddenly appeared without any pain, pruritus or trauma. Laboratory investigation showed no abnormalities. Histopathology revealed non-inflammatory actinic purpura. These purpura are frequently seen in older people due to a weakened collagen framework.
