Hematoma vs. Bruise | Complete Details

Follow us

The human skin, our largest organ, not only covers the body in order to protect the internal structures but also signals if anything goes wrong inside it. By noticing a change in the color or texture of the skin, many health issues can be primarily identified. Similarly, the skin expresses bruises, hematomas, or other colored painful spots which appear on it due to varying reasons. But what is the difference between a hematoma and a bruise? How to differentiate them? Once identified, how should I give primary care? This article answers many of these frequently asked questions regarding hematomas as well as bruises. So let’s dive in.

What is a hematoma?

A hematoma is the extravascular accumulation of blood under the skin due to the bursting of a blood vessel. This results in bulging or inflammation at the target site.

Causes of a hematoma

The common causes of hematoma formation in the body include:

  • Presence of aneurysms
  • Bone-related injuries
  • Use of certain medicines
  • Presence of viral infections in the body such as chickenpox, mumps, rubella, HIV, or hepatitis C
  • Recent phlebotomy i.e. puncturing of blood vessel with the aim to draw blood or administer a fluid or a drug
  • Presence of a disease e.g. leukemia

Symptoms of hematoma

Now if you are thinking, ‘What does a hematoma look like?’ here is the answer. The following are the symptoms of a hematoma which help to identify them:

  • Redness as well as tenderness of the skin
  • Pain and inflammation
  • The feeling of warmth at the affected site

How to diagnose a hematoma?

For the diagnosis of a hematoma, your physician might first look at your symptoms which can give away a soft tissue hematoma. However, if there is an indication of a severe hematoma, then any of the following tests can be recommended for confirmation:

  • CT scan
  • X-rays
  • Ultrasound
  • MRI

How to treat a hematoma?

For the treatment of a hematoma, simple home remedies and some rest can indeed work like magic. These include putting ice cubes on the affected area and self-medicating with painkillers such as Tylenol or Advil. Painful hematoma can be managed by practicing the RICE method which includes:

  • Rest and protect the affected site
  • Ice or a cold pack which is to be put onto the hematoma
  • Compression was applied to the affected area by wrapping the site
  • Elevating or supporting the injured site

However, if the hematoma does not subside by doing these, it is best to consult your physician.

Are you at risk of hematoma formation?

Individuals with any of the following are more prone to hematoma formation than others:

  • Progressing age
  • Traumatic experiences in the recent past
  • Use of blood thinning medications i.e. anticoagulants

What is a bruise?

A bruise, often termed a contusion, is a painful outgrowth on the skin which is formed as a result of the microscopic rupture of the blood vessels due to a recent trauma or an injury.

Causes of a bruise

The following may be the causes of bruising in the body:

  • Bumps or accidents
  • Tearing of the blood vessels adjacent to the skin
  • Thinning of the skin due to old age
  • Bleeding disorders

Symptoms of bruising

The appearance of the following may indicate the presence of a bruise:

  • Purplish or bluish appearance of the skin at the affected area
  • Pain and tenderness around the affected site

Changing the colors of a bruise over time

Diagnosis of a bruise

The diagnosis of a bruise is easy as compared to a hematoma because the individual can self-identify the changes in the skin texture and color. If it is severe, then it is advised to consult a physician who might want to go for an X-ray. However, if the bruising is frequent, it is better to run some tests to rule out the possibility of a bleeding disorder or, in another case, to confirm it.

How to treat a bruise?

A hematoma and a bruise, however different, can be treated by similar methods. The employment of the RICE method is also recommended in case of a bruise.

Are you at risk of bruising?

If you have any of the following health conditions, you may be at risk of experiencing bruising:

  • Prolonged vitamin C deficiency
  • Presence of bleeding disorders
  • Use of anticoagulants

A hematoma, like a bruise, is a modification in the color and texture of a skin patch. Although both occur due to different reasons, it is possible to identify them and provide primary care at home. In most cases, this initial care is enough to get rid of a hematoma or a bruise but if not effective, it is advised to consult a physician for proper therapy.
