How can you best describe actinic purpura?

1. Small raised lesions on the skin

2. Flat, purple discolorations without trauma

3. Rash associated with viral infection

4. Scar-like formations from previous trauma

The correct answer is: Flat, purple discolorations without trauma

Actinic purpura is best described as flat, purple discolorations on the skin that occur without any notable trauma. These lesions are caused by the fragility of blood vessels that become more prominent with age and are often seen in areas of the skin that have been exposed to the sun, such as the arms and hands. The condition arises from the breakdown of collagen and the connective tissue supporting the vascular structures in the skin, making them more susceptible to rupture. This results in blood leaking into the surrounding tissue, leading to the characteristic purplish-colored spots known as purpura. While other descriptions may refer to different skin conditions or changes, actinic purpura is specifically characterized by its flat nature and lack of associated trauma, distinguishing it from other skin lesions that may be raised, scarring, or related to infections.
