Troubled at the sight of the tiny round red spots in your leg? You may be, in all probability, suffering from Petechiae, a unique medical condition. Read on to know all about Petechiae.
What is Petechiae? It is very easy to define Petechiae. Petechiae are round red spots appearing on the skin. The spots are initially red in color. In later stages, however, they may appear blue or purple in color. A single dot is called Petechia. A cluster of Petechia is known as Petechiae. The condition can apply to any of three purpuric skin ailments.
Petechiae are normally accompanied by external symptoms like the appearance of small round dots in the skin. Unlike rashes, which are raised spots on the skin, these are flat. This is because these are not formed over the skin but under it.
The spots are very tiny. Generally, each of them is less than 3 mm in diameter. These do not blanch when they are pressed upon.
In the early stages, the dots are red in color. But in advanced stages, the color can change to blue or purple. The spots generally appear on the leg, but they may get distributed in other parts of the body in later stages.

Petechiae may also happen if a body tissue comes under excessive pressure, as in case of using a compression bandage.
The condition may also arise if the person has recently suffered from a disease with fever. In such cases, it indicates the presence of bacteria such as Meningococcus in the bloodstream.
The red spots may also develop due to allergic reaction of the body against medications.
When a person suffers from an autoimmune disorder, the body starts producing antibodies which turn against its own tissues and other naturally present substances. This can lead to a damage of the tissues and leaking of blood.
Medical conditions such as Leukemia or other malignant conditions of the bone marrow can also lead to a reduction in the number of platelets and cause this disorder.
Infection by virus can sometimes lead to impaired blood clotting and the formation of this syndrome.
Certain drugs like Aspirin, Heparin, Cortisone and Warfarin can also cause this condition.
The condition may also arise as a side-effect of treatment by radiation and chemotherapy.

Low platelet count may be the reason behind the appearance of Petechiae in many cases. A transfusion of platelets is highly necessary for treating such patients.
If the patient suffers from a malignant disease like cancer or leukemia, surgery may be necessary in some cases.
Petechiae resulting from injury are not too dangerous and can be treated by pressing the affected area with an ice-pack from time to time. If treated like this, the spots normally take a day or two to vanish after the injury. This is usually a case of mild Petechiae.
