Purpura, also called blood spots or skin hemorrhages, refers to purple-colored spots that are most recognizable on the skin. The spots could also be located on organs or mucous membranes, including the membranes on the inside of the mouth. Purpura occurs when small blood vessels burst, causing blood to pool under the skin. This can create purple spots on the skin that range in size from small dots to large patches. Purpura spots are generally benign, but may indicate a more serious medical condition, such as a blood clotting disorder.
