What is Petechaie?

Petechiae are small red spots that appear on the skin and are typically red, brown, or purple. They are the result of tiny capillaries discharging blood underneath the skin. There are many reasons for the formation of petechiae. These reasons can fall anywhere in a wide spectrum of severity, from minor to very major.

Differentiating Petechiae

What is Petechaie?There are several characteristics unique to petechiae that can help to differentiate them from other skin irritations or rashes:

  • Size. Petechiae are typically around .05-1 mm in diameter and not more than 3mm.
  • Location. While petechiae can form pretty much anywhere on the body, they are most commonly found on the legs, face, ankles, back, thighs and shoulders.
  • Color. Petechiae initially begin usually with a red color and then turn to blue or purple.
  • Don’t fade with pressure. The greatest identifier is to apply pressure to the area. If the spots do not fade or lighten, they are most likely petechiae.

What Causes Petechiae?

There are a multitude of factors that can cause petechiae bleeding, for example:

  • Prolonged straining. Excess straining from coughing, vomiting or crying are the most common causes of petechiae. In these cases, the rash-like rupture spots usually form on the face, especially around the eyes. Childbirth and weightlifting are additional examples of strain-induced petechiae. These types of petechiae are typically harmless and disappear in a few days.
  • Specific medical conditions. There are several noninfectious and infectious medical conditions that cause the formation of petechiae. A few examples of the noninfectious roots of petechiae are:
    1. Thrombocytopenia - A blood platelet deficiency disorder
    2. Aplastic anemia - When bone marrow stops producing a sufficient amount of blood forming stem cells
    3. Leukemia - Cancer of the blood cells
    4. Vitamin K Deficiency - Heightens the risk of uncontrolled bleeding, since vitamin K plays a large part in the clotting of blood

What is Petechaie?

Petechiae can also be caused by infectious bacteria or viruses, such as:

    1. Strep throat - Bacterial infection that causes a severe sore throat
    2. Sepsis - Infection of the blood
    3. Infectious mononucleosis - Also called “the kissing disease,” a viral infection that can lead to an enlarged spleen
    4. Meningitidis - Severe bacterial disease that can lead to sudden fever and headache
    5. Rocky Mountain spotted fever - Bacterial infection passed by tick bites that can lead to serious kidney and heart damage
  • Specific types of injuries. Strangulation, smothering, biting and spanking can cause petechiae. Severe sunburns can also cause the formation of petechiae.
  • Medications. Petechiae can also form as a reaction to specific drugs. A few examples are:
    1. Warfarin
    2. Naproxen
    3. Heparin
    4. Cimetidine
    5. Carbamazepine
    6. Aspirin
    7. Cortisone

The best way to treat and manage petechiae is to correct the underlying cause.
