Broken blood vessels
Bleeding into the skin can appear as small dots, called petechiae, or in larger, flat patches, called purpura. Some birthmarks can be mistaken for bleeding into the skin. Normally, when you press your skin it becomes pale, and when you let go, the redness or color returns. When there is bleeding into the skin, the skin will not become pale when you press down on it.
Bleeding beneath the skin often results from a minor occurrence, such as bruising. The bleeding can appear as a small dot the size of a pinprick or as a patch as large as an adult hand. Bleeding into the skin may also be the sign of a serious medical condition. Always see a doctor about bleeding into the skin that is not related to an injury.
