Keep looking.: Purpura is the result of blood leakage into the skin. It may represent a relatively benign condition or herald the presence of a significant underlying disorder such as low platelet levels, coagulation factor deficiencies, or a vascular defect. Testing should be continued until the cause is found, particularly if fever is also involved.
