Petechiae
Petechiae or Petechial rash is a spot of red or purple color caused due minor hemorrhage. These spots usually occur on legs which may appear like rash initially but actually they are in clusters. These are small rashes of less than 3 mm diameter.
Petechial rash appear when blood vessels (capillaries) bleed and this blood is leaked into the skin. A number of factors like medical conditions, infections, trauma etc. can cause these capillaries to bleed. Petechial rashes are not harmful and disappear on their own within few days.
There are certain features of Petechiae that will help in early detection and differentiate these rashes from other diseases.

There are certain medications too that can cause petechial rash. Some of these medicines include:
Also, Petechial rash on the skin and inner surface of mouth can be a result of infectious diseases. Following are some of the viral, bacterial and fungal infections that may cause petechial rash:
Petechial rash can also be caused due to noninfectious medical conditions like Hemolytic uremic syndrome, Vitamin deficiency, infantile scurvy, Idiopathic thrombocytopenic purpura and vasculitis.
There are many causes of petechial rash in children but some of them can be serious. Therefore it is imperative to seek medical care if rashes are caused by some serious condition:
Meningococcal infection: Often it starts as balanced rash and child may also have fever. In this condition rash may appear before eyes and can be very serious.
Idiopathic thrombocytopenia purpura: The child may develop large bruises caused due to low platelet count. Mostly, this condition resolves on its own but sometimes treatment may be required.
Leukemia: leukemia is a cancer of bone marrow that causes low blood cells. In this condition the child becomes pale and develops rash.
Infections: Any severe infection is likely to interfere with normal body clotting system.
The symptoms of Petechiae depends on underlying condition along with petechiae spots. Infections which may lead to rash are often accompanied by malaise, fever and flu.

- The size of the Petechial rash ranges from 0.3 mm to 3 mm. Usually it is of 0.4mm to 1mm in diameter. Petechiae spot is tiny hemorrhagic spot and its larger form is known as purpura.
- Typically Petechiae can appear on any part of the body but it is most common in the areas like face, legs, thighs, ankles, back and shoulder.
