Tiny pink dots around your eyelid. A small black-and-blue galaxy on your thigh. Purple splotches down your back. Bruising is one of the most common symptoms of immune thrombocytopenia (ITP), a condition that causes low platelet counts and increases the risk of bleeding.
If you’re living with ITP and develop a bruise, you may wonder whether they’re from the condition, a normal response to sustaining an injury, or something else.
In this article, we’ll look at the different types of ITP bruises, what causes them, what they may look and feel like, and how you can manage them.
ITP is a disease that lowers the amount of platelets in your blood. Platelets are cell fragments that help blood clot. Fewer platelets lead to a number of ITP symptoms, including:
When you partake in normal activities, such as cooking, cleaning, or going out with friends, you may notice that you bruise more easily and severely than the average person. Most of the time, you may not even remember anything that may have caused it.
An increase in bruising may be a sign that platelet counts have dropped. The lower your platelets, the worse your symptoms may be. However, it’s important to keep in mind that many factors can worsen bruising, including the location and underlying causes of the bruise and your body’s ability to heal.
It’s important to monitor your symptoms and communicate any changes or concerns with your healthcare provider. The only way to know the severity of your ITP is through blood and other laboratory testing.
ITP treatments that can cause bruising include:
Most ITP treatments help reduce symptoms and bruising by increasing platelet counts or slowing down platelet destruction. However, long-term corticosteroid use can thin the skin and make bruising happen more easily. Newer ITP treatments like SYK inhibitors or BTK inhibitors can cause unusual bruising or bleeding for some people.
Other types of ITP treatment may cause skin symptoms that appear like bruising. For example, a platelet transfusion or IVIG may cause a rash in some people. A rash may look different from a bruise, but appearance and symptoms vary.
Speak to your doctor if you experience side effects of your ITP treatment or if you think that it’s not working well enough to control your symptoms.
Bruises caused by ITP generally look like other bruises. Depending on your skin tone, a new bruise may appear red, purple, blue, black, or darker than the surrounding skin.
As the body breaks down the blood trapped under the skin, the bruise often changes color over time. It may turn green, yellow, or brown before eventually fading away.
Because bruising may be harder to recognize on certain skin tones, pay attention to other possible signs, such as:
If you notice new or worsening bruising, especially along with other bleeding symptoms, contact your healthcare provider.
There are many kinds of bruises that are commonly found in people with ITP. Learning the different types can make it easier to discuss symptoms with your healthcare team.
Purpura is a type of bleeding under the skin that appears as purple, red, or brownish patches. It’s commonly seen in people with ITP and occurs when small blood vessels leak blood into the skin. Purpura can range from small spots to larger patches that are smaller than bruises.

Petechiae are tiny, red, purple, or brown pinpoint spots caused by bleeding from very small blood vessels. They’re often smaller than purpura, commonly appear on the lower legs, and may even resemble a rash.
People with more severe ITP may be more likely to develop petechiae, although it can still appear at any stage.

Ecchymosis, the medical term for bruises, occurs when bleeding collects under the skin, usually after a minor injury or bump. Everyone bruises at some point in their life, regardless of if they have ITP.
Ecchymoses are often larger than petechiae and may appear blue, purple, black, or brown depending on skin tone. They might also feel tender or sore, and in some cases, they may look raised or swollen.
People with ITP may develop ecchymoses more easily and from less force than people without low platelet counts.
Bruising in ITP can feel different for each individual. In general, bruises caused by low platelet counts from ITP may feel tender or sore to the touch like other bruises. The amount of pain or discomfort associated with a bruise can vary depending on the location, size, and severity of the bruise.
In addition to bruising, people with ITP may experience other symptoms related to low platelet counts, such as nosebleeds, bleeding gums, and heavy menstrual bleeding.
In severe cases, internal bleeding can occur, which can cause symptoms such as blood in the urine or black or tarry stool.

To prevent bruising while living with ITP, you can try the following:
If your symptoms are difficult to tolerate or are interrupting your life, talk to your doctor. There may be additional treatment options that could help reduce bruising and other symptoms. It’s important to communicate with your doctor about all potential symptoms and side effects.

I think blood thinners cause this!
I’ve had bruising over 7 yrs & Drs do nothing & don’t know why.
Have them check for ITP. Keep a record of your bloodwork, and check your platelets! I just finished 4 rounds of Retuximb infusions for low platelets ITP.
What blood test shows platelet count?
CBC Has always told me what my platelet count was. I have had ITP for 25 years, and my platelets always seem to stay in the danger zone. Around 25,000 or so ! 😒 But I have learned to live with it !!
It displays itself on my right side...arm and leg foll8wed by or pre-emted by ulcers. Bleeding leaves me weak and frankly in shock. I have SLE and am on medication. This is a devastating disease to live with for someone who has been a GI Jane and very active. I feel it is caused by inherent stress... from the womb thru childhood. And wondered if someone in the medical field couldn't do a census on this?
I have been experiencing this for over 3 years now. Sometimes Factor 8, 9 or 10 are abnormal but not consistently. RBC and WBC are typically low but Platelets are in normal range. I have been getting worse with the bruising, just rubbing a mosquito bite causes the little red dots to appear in that location because the huge bruising on my legs and body.
I have had Purpura for years, since I was 8 years old was dx with Henoch-Schonlein purpura, later dx with RF and then in my 30's with SLE and ANTIPHOSPHOLIPID ANTIBODY Syndrome. The new Rheumatologist has not seemed to be concerned at all and basically ignores the increase in the purpura, and bruising, The bruising appears out of nowhere and 24 hours hours later can be gone and back again in hours, I have had this before, sometimes accompanied by low grade fever. I will be 69 tomorrow and had PE last year and DVT 2times in the past. was on Plavix for several years and discontinued, now on Eliquis. It's been a struggle. Not to mention the AA with a stent I had in 2014. It seems my whole vascular system has been affected now they say I have early onset Vascular Dementia, mild. ( could it be all tied together? ) Platelets vary as well.
