Profile: Petechiae
Definition:
A small, flat, pinpoint spot that is violet, red, or brown, located under the skin or on the mucous membranes (mouth, eyelids), which is neither raised nor bumpy. It is caused by the rupture of blood capillaries, leading to bleeding under the skin. Petechiae typically appear on the arms, legs, stomach, and buttocks. They can sometimes appear in clusters, resembling a rash, but it is not one.
Internal and external causes:
Bacterial or viral infection, injury, reaction to a medication (antibiotics, antidepressants, and blood thinners), vasculitis.
How to reduce or eliminate:
Taking antibiotics to treat a bacterial infection; taking corticosteroids to reduce the swelling of blood vessels
Preventative steps to take:
Avoid the medication causing petechiae; regularly wash your hands with water and soap.
