I'm an expert in medical sciences with a focus on dermatology and internal medicine. When it comes to petechiae, which are small, pinpoint, non-raised, round, and often reddish or purple spots on the skin, they can be caused by a variety of factors. The main causes of petechiae include:
1. Increased Vascular Fragility: The skin's capillaries can become fragile due to various reasons, leading to petechiae.
2. Thrombocytopenia: A decrease in the number of platelets in the blood can lead to petechiae because platelets are crucial for blood clotting.
3. Infection: Certain infections, like meningitis or sepsis, can cause petechial rashes.
4. Vascular Disorders: Conditions that affect the blood vessels, such as vasculitis, can result in petechiae.
5. Medications: Some drugs can cause petechiae as a side effect, particularly those that affect blood clotting.
6. Trauma: Physical injury to the skin can also lead to petechiae.
It's important to note that while these are common causes, the appearance of petechiae should be evaluated by a healthcare professional to determine the underlying cause and appropriate treatment.

Petechiae are formed when tiny blood vessels called capillaries break open. When these blood vessels break, blood leaks into your skin. Infections and reactions to medications are two common causes of petechiae. ... A sunburn can also cause petechiae.
