What term describes the escape of a small amount of blood resulting in pinpoint spots?

1. Petechiae

2. Ecchymosis

3. Telangiectasia

4. Induration

The correct answer is: Petechiae

The term that best describes the escape of a small amount of blood that leads to pinpoint spots on the skin is "petechiae." Petechiae are tiny, round spots that appear as a result of bleeding under the skin. They can range in color from red to purple and are often a sign of various medical conditions, indicating possible issues with blood clotting or capillary fragility. Understanding petechiae is essential for identifying underlying health issues, as they can be symptomatic of conditions like thrombocytopenia or infections. In contrast, ecchymosis refers to larger bruises that result from bleeding underneath the skin but represent a more extensive area of discoloration than petechiae. Telangiectasia refers to small dilated blood vessels near the surface of the skin, giving a different appearance, more like small red lines or spider veins. Induration is a term that describes a hardening of tissue, often due to inflammation or infection, and does not refer to any bleeding into the skin. Each of these terms describes distinct phenomena related to blood vessels and bleeding, with petechiae being the specific term for small pinpoint spots.
