Ecchymosis is the medical term for what most people call a bruise, those dark blue, purple, or green patches that appear on the skin after small blood vessels under the surface break and leak blood. The color changes happen as your body gradually reabsorbs this blood during healing.
A bruise can show up anywhere on the body, including the arms, legs or face and usually fades on its own. However, frequent or unexplained bruising can sometimes be a sign that your body needs medical attention.
The definition of ecchymosis is a flat area of discoloration caused by bleeding underneath the skin, usually larger than 1 centimetre. Unlike minor spots called petechiae (tiny red dots) or purpura (mid-sized patches), ecchymosis covers a larger area and may change colors as it heals.
Petechiae, purpura, and ecchymosis are often discussed together because they all involve bleeding under the skin. The difference lies mainly in their size and causes.
Understanding these terms helps doctors identify possible bleeding disorders or underlying conditions.
Ecchymosis causes vary depending on your age, health, and daily activities. Most bruises occur after a bump, fall or minor injury. However, some appear without any apparent reason, especially as we age or when certain medicines affect how blood clots.
Common causes include:
If you notice bruises on your legs for no reason or frequent bruises on your body that take longer to fade, it's best to discuss this with your healthcare provider.
Periorbital ecchymosis, often called "raccoon eyes", refers to dark bruising around one or both eyes. It can occur after a head injury, facial trauma, or surgery, but sometimes signals a more serious condition such as a skull fracture or internal bleeding.
When bruising occurs directly on the eyelid or below the eye, commonly referred to as ecchymosis eye, it may simply result from a bump or cosmetic procedure. Still, persistent or severe discoloration should be checked by a doctor immediately.
If you notice swelling, vision changes, or pain with an eye bruise, seek prompt medical attention.
Although they may look similar, ecchymosis vs. hematoma describes two different things:
In short, all hematomas cause bruising, but not all bruises are hematomas. Ecchymosis tends to be more superficial, while a hematoma is deeper and may take longer to resolve.
Most bruises heal without any special care. However, see your doctor if:
Persistent or unexplained ecchymosis can sometimes be an early sign of a bleeding disorder or other health condition, so it’s always best to get checked if something feels unusual.
Ecchymosis treatment depends on its cause, but most bruises can be cared for at home with a few simple steps:
If your doctor identifies an underlying cause, treatment may include adjusting medications, improving diet or managing related medical conditions.
While not all bruises can be prevented, small changes can help protect your skin and blood vessels:
These small steps not only help prevent ecchymosis but also promote firmer, healthier skin overall.
Get in Touch with a Doctor
Yes, bruises can appear without obvious trauma, especially in older adults or those taking blood-thinning medications. Unexplained bruising should be discussed with a doctor to rule out underlying conditions.
Certain medications, like blood thinners, steroids, or some supplements, can make bruising more likely by affecting clotting or weakening blood vessels. Always consult your doctor if you notice frequent bruises.
For most bruises, apply a cold compress initially, elevate the area, use a warm compress after 48 hours, avoid massaging, and protect the area to help it heal safely and comfortably.
Ecchymosis refers to large, flat bruises under the skin, while petechiae are tiny red or purple dots caused by pinpoint bleeding. Size and appearance help doctors distinguish between them.
A deficiency in Vitamin C or Vitamin K can make blood vessels fragile, increasing the risk of bruising. Eating fruits, vegetables, and leafy greens usually helps prevent ecchymosis.
