What are petechiae?

Large hemorrhages under the skin

Small hemorrhages under the skin

Petechiae are defined as small hemorrhages that appear as tiny red or purple spots on the skin. They occur when small blood vessels, called capillaries, break and leak blood into the surrounding tissue. The size of petechiae is typically just a few millimeters, which distinguishes them from larger types of hemorrhages, such as ecchymoses or hematomas. Understanding petechiae is important in clinical settings, as they can indicate a variety of underlying medical conditions, including clotting disorders, infections, or trauma. In summary, the correct answer emphasizes the small size and specific nature of these skin manifestations, making it essential to recognize their significance in a medical assessment.
