Are contusion and ecchymosis the same thing?

How do you differentiate a hematoma?

The most obvious difference between a hematoma and a hemorrhage is that a hemorrhage may bleed externally. Hemorrhages may also bleed internally and this would not be visible. Hematoma symptoms may include bluish or purplish discoloration of the skin (a bruise) or a lump under the skin.

What is a Haematoma?

A hematoma is a bad bruise. It happens when an injury causes blood to collect and pool under the skin. The pooling blood gives the skin a spongy, rubbery, lumpy feel. A hematoma usually is not a cause for concern. It is not the same thing as a blood clot in a vein, and it does not cause blood clots.

What is an example of ecchymosis?

Like bruising, it is most common on legs and arms, and it often results from minor injuries sustained, for example, by bumping into furniture. Ecchymosis also frequently appears in areas where the skin is thin, such as the eyelids or lips.

What is the difference between petechiae and ecchymosis?

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).

Is ecchymosis a bruise?

How can you tell the difference between an extradural and subdural hematoma?

Extradural haematoma (EDH) is a blood clot that forms on the outside of the natural covering of the brain (‘dura mater’), while acute subdural haematoma (ASDH) refers to a blood clot on the inner surface of the dura that appears within the first few days of head injury.

What is difference between purpura and petechiae?

Petechiae are small (1–3 mm), red, nonblanching macular lesions caused by intradermal capillary bleeding (Figure 181-1). Purpura are larger, typically raised lesions resulting from bleeding within the skin (Figures 181-2 and 181-3).

What is the difference between a contusion and a hematoma?
