A picture gallery displaying graphic images of purpura rashes is available at Healthline. Purpura presents itself with purple spots that range from small dots to larger patches, and they may appear on the skin, mucous membranes and internal organs.
Purpura is also known as blood spots or skin hemorrhages, and it occurs when small blood vessels burst under the skin, says the National Institutes of Health. Purpura spots that are less than 3 millimeters in diameter are called petechiae, while purpura spots exceeding 1 centimeter are called ecchymoses. Individuals displaying signs of purpura should consult a doctor for the best course of action.
