Bleeding into the skin
Ecchymoses; Skin spots - red; Pinpoint red spots on the skin; Petechiae
Bleeding into the skin can occur from broken blood vessels that form tiny 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).
Purpura
Purpura is purple-colored spots and patches that occur on the skin, and in mucus membranes, including the lining of the mouth.
Considerations
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 paler (blanch) when you press on the area, like the redness from erythema does.

Home Care
Protect aging skin. Avoid trauma such as bumping or pulling on skin areas. For a cut or scrape, use direct pressure to stop the bleeding.
If you have a drug reaction, ask your provider about stopping the drug. Otherwise, follow your prescribed therapy to treat the underlying cause of the problem.
When to Contact a Medical Professional
Contact your health care provider if:
- You have sudden bleeding into the skin for no apparent reason
- You notice unexplained bruising that does not go away
What to Expect at Your Office Visit
Your provider will examine you and ask questions about the bleeding, such as:
- Have you recently had an injury or accident?
- Have you been ill lately?
- Have you had radiation therapy or chemotherapy?
- What other medical treatments have you had?
- Do you take aspirin more than once a week?
- Do you take Coumadin, heparin, or other "blood thinners" (anticoagulants)?
- Has the bleeding occurred repeatedly?
- Have you always had a tendency to bleed into the skin?
- Did the bleeding start in infancy (for example, with circumcision)?
- Did it start with surgery or when you had a tooth pulled?
The following diagnostic tests may be performed:
-
Coagulation
tests including INR and prothrombin time
Coagulation
Bleeding time is a medical test that measures how fast small blood vessels in the skin stop bleeding.
