Do you have a rash on your skin that is causing you concern? If so, it is important to seek medical attention right away. While there are many types of rashes, one type in particular that you should be aware of is palatal petechiae. Petechiae are small, red spots on the skin due to bleeding underneath the surface. In this blog post, we will discuss petechiae, what causes them, and what they may indicate about your health.
What is Petechiae?
Petechiae are small, red, or purple dots on your skin. They occur when tiny blood vessels called capillaries burst and leak under the skin. Petechiae usually appear on your arms, petechiae on legs, stomach, and buttocks. On people with lighter skin, petechiae often look like a rash. But on people with darker skin, may look more like bruises.
The dots are usually less than three millimeters (mm) in diameter and don’t blanch when you press on them. Petechiae can appear as a few spots scattered across your body, or they can cluster together to form a larger patch of discolored skin.

Causes of Petechiae
The most common causes of petechiae are:
- Chronic Diseases
Leukemia, idiopathic thrombocytopenic purpura (ITP), and other blood disorders can cause petechiae. In these cases, the petechiae are often signs of a more serious underlying condition.
Other chronic diseases that may cause petechiae include:
- Autoimmune diseases
- Vitamin C or B12 deficiency
- Endocarditis (inflammation of the heart)
- Hypertension (high blood pressure)
Infections are a common cause of petechiae. Viral infections that can cause petechiae include:
- Scarlet fever
- COVID-19 Infections that cause petechiae can also be bacterial, such as:
- Other Factors
Other factors that can cause petechiae include:
- Allergic reactions
- Chronic coughing
- Straining during a bowel movement
- Sneezing hard
Physical trauma, such as car accidents or sports injuries, can also cause petechiae. If the force is great enough, it can break blood vessels and cause bruising and internal bleeding. Petechiae usually don’t cause any other symptoms.
Symptoms of palatal petechiae
Most of the time, petechiae doesn’t cause any symptoms. If they do, it’s usually because of the underlying condition. For example, if you have a viral infection, you might also have:
- a fever
- body aches
If you have petechiae on legs, ankles, or feet, you might also notice:
- bleeding from your gums or nose
- easy bruising
- tiny red dots on your skin that turn brown over time (petechiae vs purpura)
- bloody stool
You might also experience lightheadedness and trouble breathing if the condition is severe. This could be a sign of internal bleeding and requires immediate medical attention.
What does Skin Discoloration Signify?
The word “petechiae” comes from the Greek word petichion, meaning “spot.” Petechiae often appear in clusters and may look like a petechial rash. They may be found on the face, neck, chest, legs, or anywhere else on the body. The skin discoloration is a result of bleeding beneath the skin.
When to see a Doctor?
palatal petechiae can be a symptom of a severe underlying condition, so it is important to seek medical attention if you have any concerns. If you have petechiae, make an appointment to see your doctor as soon as possible.
In some cases, petechiae may resolve on their own without treatment. However, if the rash does not go away or gets worse, it may be a sign of a more serious condition and require treatment. Treatment for petechiae will depend on the underlying cause.
If you have petechiae, your doctor will likely perform a physical examination and ask about your medical history. They may also order blood tests to check for conditions that can cause petechiae or other symptoms. Follow your doctor’s instructions and call them if you have any questions or concerns.
Treatment for Palatal petechiae
There is no specific treatment for palatal petechiae. If the cause is unknown, your doctor may order a blood test to rule out a more severe condition. Treatment will focus on resolving the underlying problem if the cause is known and it’s due to an injury or infection. In some cases, petechiae may go away on their own without treatment.
The Bottom Line
Petechiae usually occurs when tiny blood vessels called capillaries break open and leak blood into your skin. Petechiae typically appear on your arms, legs, stomach, and buttocks. While they’re not a cause for concern, petechiae can sometimes signify a more serious medical condition. If you have petechiae or a petechial rash, see your doctor, find out what’s causing it, and get treatment.
