Petechiae are small (1-2mm) red or purple spots on the body, caused by a minor hemorrhage (broken capillary blood vessels).

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.
