Which term refers to a red-purple discoloration of the skin caused by multiple minute hemorrhages?

The correct term that refers to a red-purple discoloration of the skin caused by multiple minute hemorrhages is purpura. Purpura encompasses a broad range of skin lesions characterized by larger patches of purple or red discoloration, typically resulting from bleeding underneath the skin due to various causes, including clotting disorders, vascular issues, or trauma.

In contrast, petechiae refer to very small, pinpoint-sized hemorrhages that do not typically form larger areas of discoloration. Ecchymosis is often used to describe larger bruises that occur due to trauma and are caused by the accumulation of blood outside vessels but is generally not used to refer to minute hemorrhages. Hyperemia is the increased blood flow to a particular area, resulting in redness and warmth, but it does not indicate bleeding into the skin. Therefore, purpura accurately reflects the symptoms described in the question.
