Have you ever noticed tiny red or purple spots on your skin that don’t fade when you press them? These spots, known as petechiae, may seem harmless at first, but they can be signs of serious underlying conditions.

In this blog, we’ll explore what petechiae are, what causes them, how to differentiate them from other skin issues, and when to seek medical help. Understanding petechiae is essential for timely diagnosis and appropriate treatment, especially when they are symptoms of serious conditions like infections, blood disorders, or autoimmune diseases.

What Are Petechiae?

Petechiae (pronounced puh-TEE-kee-ee) are small, pinpoint-sized, flat spots on the skin, typically red, purple, or brown in color. They result from minor bleeding under the skin due to the rupture of small blood vessels (capillaries). Petechiae often appear in clusters and may resemble a rash.

What makes petechiae unique is that they don’t blanch (fade) when pressed, unlike other skin discolorations. They can appear anywhere on the body but are most commonly found on the arms, legs, stomach, buttocks, and inside the mouth or eyelids.

Petechiae vs. Purpura vs. Ecchymosis

It’s important to distinguish petechiae from similar skin conditions:

ConditionSizeColorBlanching on PressureCommon Cause
Petechiae< 2 mmRed/purpleNoCapillary rupture
Purpura2–10 mmPurpleNoPlatelet disorders, vasculitis
Ecchymosis> 10 mmBlue/purpleNoBruising, trauma

Symptoms of Petechiae

Petechiae themselves are not painful or itchy, but they are indicators of an underlying issue. Depending on the cause, petechiae may be accompanied by:

If you experience petechiae with any systemic symptoms, it could be a medical emergency.

Causes of Petechiae

Petechiae can result from both non-serious and serious causes. They typically indicate bleeding under the skin due to low platelet count, capillary fragility, or blood clotting disorders.

  • To detect blood or infection

4. Imaging

  • Chest X-ray or CT scan: If infection has spread

5. Bone Marrow Biopsy

  • In cases of suspected leukemia or aplastic anemia

Treatment of Petechiae

Pregnant Women:

  • Can be a sign of HELLP syndrome, thrombocytopenia, or liver dysfunction

Complications of Untreated Petechiae

Ignoring petechiae can lead to severe complications, depending on the underlying cause:

  • Internal bleeding

  • Septic shock

  • Organ failure

  • Death (especially in meningococcal infections or DIC)

Hence, timely diagnosis and treatment are critical.
