Purpura, also called blood spots or skin hemorrhages, refers to purple-colored spots that are most recognizable on the skin. The spots may also appear 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.
Purpura rash. The rash that is associated with purpura is sometimes referred to as either skin hemorrhages or blood spots. You will find them all over your skin in various parts of your body but mostly in your arms and lower legs. They are usually smalls dots that tend to blister and are reddish-purple in color.
Purpura is characterized by small purple spots on the skin, typically 4-10 millimeters in diameter. Some people develop larger patches of 1 centimeter or greater. These are called ecchymoses. Sometimes the spots can appear on mucous membranes, for instance, inside the mouth. Purpura tends to occur in clusters...
Purpura are patches of blood trapped under the skin, outside of a blood vessel. Because the blood is not inside an artery or vein and has nowhere to go, when you press it, it does not blanch or change color.
Purpura is a skin rash usually characterized by small, purplish-red spots on skin. There are different types of purpura with varying causes. Purpura rashes are not an independent condition, but rather a symptom of another health issue.
Signs and Symptoms of Yellow Spots on skin. Purpura on your skin can show up as flat spots, patches or raised bumps that range in size from pinpoint sized to largely visible marks. Raised purple spots are usually blood-filled blisters that can develop on the surface of the skin.
Solar purpura (also known as "Actinic purpura," and "Senile purpura") is a skin condition characterized by large, sharply outlined, 1- to 5-cm, dark purplish-red ecchymoses appearing on the dorsa of the forearms and less often the hands. The condition is most common in elderly people of European descent. It is caused by sun-induced damage to the connective tissue of the skin. No treatment is necessary. The lesions typically fade over a period of up to 3 weeks.
A petechia is a small (1–2 mm) red or purple spot on the skin, caused by a minor bleed from broken capillary blood vessels.Petechia refers to one of the three descriptive types of bleeding into the skin differentiated by size, the other two being purpura and ecchymosis. Petechiae are by definition less than 3 mm. The term is almost always used in the plural, since a single lesion is seldom noticed or significant.
Purpura is a condition of red or purple discolored spots on the skin that do not blanch on applying pressure. The spots are caused by bleeding underneath the skin secondary to platelet disorders, vascular disorders, coagulation disorders, or other causes. They measure 0.3–1 cm (3–10 mm), whereas petechiae measure less than 3 mm, and ecchymoses greater than 1 cm. Purpura is common with typhus and can be present with meningitis caused by meningococci or septicaemia. In particular, meningococcus (Neisseria meningitidis), a Gram-negative diplococcus organism, releases endotoxin when it lyses. Endotoxin activates the Hageman factor (clotting factor XII), which causes disseminated intravascular coagulation (DIC). The DIC is what appears as a rash on the affected individual.
