Question

Quizplus · Accepted Answer

The fact that the discoloration blanches temporarily with direct pressure indicates that the lesion is related to vessel dilation. This is because vessel dilation allows more blood to flow into the area, which causes the redness, and pressing on the area temporarily restricts blood flow and causes the discoloration to disappear. Painlessness and warmth may occur with other types of skin lesions, while the disappearance with elevation is more indicative of fluid buildup or inflammation.
