Hi, The most common cause of petechiae is through physical trauma such as a hard bout of coughing, vomiting or crying, which can result in facial petechiae, especially around the eyes. Petechiae in this instance are harmless and usually disappear within a few days. If unsure, petechiae should always be quickly investigated. They can be interpreted as vasculitis, an inflammation of the blood vessels, which requires immediate treatment to prevent permanent damage. Some malignancies can also cause petechiae to appear. Petechiae should be investigated by a doctor to rule out the more dangerous conditions. Dermatologists can be the most helpful specialists in these conditions because they can more easily identify if the condition is petechiae or some similar looking but less worrisome rash. Petechiae in children can occur with viral infections. In this instance, they do not necessarily signify a serious illness. However, they are a hallmark signal of some potentially serious illnesses, such as meningococcemia, leukemia, and certain causes of thrombocytopenia, of which meningococcemia can cause death within 48 hours of infection. Therefore, their presence should not be ignored. You should consult your doctor for other investigations if petechiae is not subsiding. There certainly be some bleeding problem secondary to other illness. Do consider a positive feedback as a credit to my work Let me know if you have any further questions.
