I have a petechiae question

I have a question I can't seem to find any clue about online. I noticed ONE CLUSTER of petechiae on my upper thigh, maybe about 7 dots in all. It fits all descriptions of petechiae, so I'm pretty sure that's what it is. However, all the information that I read about doesn't say if this small amount is a concern and should be checked out. I have it now for 2 days and it isn't fading. There was no trauma to the area. The only other symptom(s) that MAY be related is excessive fatigue and muscle pain along my arms and legs.
So my questions is, is this small amount of petechiae a concern, with or without my other symptoms?

Thanks to anyone that can help.
Not sure I can answer that question for you, but I'll provide some information from which may help you figure it out yourself.

Petechiae are small red dots or spots caused by burst capillaries.

Petechiae are common in leukemia patients because the proliferation of leukemic cells in their bone marrow is crowding out the production of various forms of good cells, including platelets. Therefore, there are only a few platelets around to fill in the "hole in the dam" when a capillary bursts and clot it up quickly.

Therefore, one of the signs of leukemia is petechiae. However, your blood doesn't lack platelets just in one small area, with a few petechiae. Your platelets are low throughout your body.

In my son's case, when he was diagnosed, he had THOUSANDS of petechiae all over his extremeties. When we got to the hospital, his platelets were down to about 20,000 (instead of the normal range of around 200-400,000).

So, are 7 small spots in one little area a concern? I don't know.
Thank you for your time and response, Djlawman

So I definitely know that it is petechiae. They are pinhead sized purplish red dots. I actually have a few more now around the same area, but nowhere else (yet) that I can tell. I hear what you're saying about it not really being a localized thing. Is it possible that it will spread so-to-speak? Or is it something that for the most part shows up all at once?
OR is it possible that it's localized and is pointing to some other disease/condition other than something drastic like leukemia?

Just a little nervous so I'm trying to see where I stand here and what to expect if and when I do go to see a physician. Which, btw, who would I see? A general practitioner? Dermatologist?

Again, thanks for your time.

I'd go to the doc and get a CBC (complete blood count) and go from there.

Hi R,

I agree with Djlawmans remarks regarding petechiae. Seven spots seem like a low number to throw the alarm switch. It certainly deserves monitoring. However, to be on the safe side, you can always phone your doctors office to see if he thinks you need to be examined right away.

Your question brings up a very good question: why dont doctors be more explicit in telling us what symptoms to watch for? It would be a simple matter for a doctor to give more detailed information that could help us make better decisions on when to seek help. If the situation is complicated, perhaps patient friendly cancer organizations could produce brochures that would be sufficiently detailed.

In my case, I am neutropenic; I was told to be forever watchful for fevers. Of course, I do not want to run to the hospital for any old fever. This seems ridiculous. Hence, I began to ask my doctors questions like: how high of a fever, how long above a certain temperature and should there be accompanying symptoms? I was very surprised at how reticent doctors were to be more explicit in telling me how to differentiate between nothing to worry about and something to rush to the nearest hospital.

This is not an academic point for me. I recently came down with a fever and chest cough. I had a fever for two days before I decided to go to the hospital. They took tests for a bacterial infection and sent me home. Two days later I got an urgent call that told me to go immediately to the nearest hospital because I had serious bacterial infection in my lungs.

Best of luck and tell us how things work out.


I would agree with Tex and get it checked out by your doc.

My son has been through aml and everytime his platelet count would drop below 20,000 he would develop petechiae on his thigh, ribs, or sternum. Most of the time in small clusters in one particular area.

But, petechiae can occur in response to a virus. I am a school nurse and sent a child home the other day because she had petechiae on her hand. Her mother took her to the doc, who agreed it was petechiae, but felt it was viral and chose to wait it out. It did subside.

There are also other causes of petechiae such as certain antibiotics that lower the platelet count. I have seen this while working in the hospital.

So numerous things can cause it, but I would certainly get it checked out by the family physician not the dermatologist. Most docs will see you immediately if you tell them you are concerned because you have petechiae. Wishing you the best.

Thank you all for your responses.

Being that I know for sure it isn't an allergic reaction (I'm not on any medication of any sort) and as I've mentioned previously it follows every description for petechiae, I will have it checked out by my PCP and take it from there.

Good luck and best of health to all.

For me, petechiae were the last thing to come up, but when it did, it was almost instantaneously all over- my wrists, knees, beltline, underarms, jawline, elbows and tops of my feet. I also had some very serious bruising- that's what got myu attention. I think that the low platelet count reached some decreasing level and then symptoms erupted everywhere, and not just petechiae. I hope that it's nothing serious, keep us posted.
HI. Do the petechiae fade or stay? I have them but they are not forming a "rash" or bruise... almost think they are like tick bites when they come up. But they just fade into small red dots that don't go away, almost like minute freckles. I am on watch and wait for MDS
petechia fades. there are other small red dots that look a lot like petechia that women can get (something to do with hormones) but they don't go away.

with petechia there will be hundreds and thousands of red dots that appear almost overnight and are pin-prick size and can grow larger/spread, etc. typically, once platelets normalize or are infused, the petechia fades and turns a rusty brownish/orange color before dissappearing entirely. when i had petechia it took about two months for the red dots to completely fade.
