Petechiae – http://id.who.int/icd/entity/262492020
Petechiae result from focal leakage of blood from dermal capillaries into the adjacent dermal connective tissue. They present as multiple pin-point non-blanching red or purple macules. The many underlying causes range from the innocuous (e.g. coughing or straining) to life-threatening conditions (e.g. meningococcal septicaemia).
