Bleeding under the skin can occur from broken blood vessels that form tiny pinpoint red dots (called petechiae). Blood also can collect under the tissue in larger flat areas (called purpura), or in a very large bruised area (called an ecchymosis).

Ecchymoses; Skin spots - red; Pinpoint red spots on the skin; Petechiae

Aside from the common bruise, bleeding into the skin or mucous membranes is a very significant sign and should always be checked out by a health care provider.

Redness of the skin (erythema) should not be mistaken for bleeding. Areas of bleeding under the skin do not become pale (blanch) when you press on the area. The redness of erythema decreases when you apply pressure to it and returns when release the pressure.
