Petechiae and Ecchymoses

July 25, 2007

The former is petechiae-small size(pinpoint areas).
The latter is ecchymoses-bigger size.
http://www.netdoctor.co.uk/diseases/facts/purpura.htmIn few days after I wrote that post I had a question from the www.usmleworld.com question bank, and according to them, the differences between petechiae, purpurae and ecchymoses are based on their size. For some reason I tought that both petechiae and ecchymoses are some kind of purpura, because of their color. Too busy to check that facts. May be later on, and also I trust usmleworld, these guys really rock.
Yes, I did quick check. That is right.
1.petechiae-less than 0.5 cm
2.purpurae-from 0.5 to 1 cm
3.ecchymoses-more than 1 cm

    I have the same condition. What can I do to help it? It hurts and I have numbness. I’ve been at many Doctor’s office (dermatologist, neurologist and cardioologists.

      Try going to an acupuncturist. They can determine and treat the cause of your condition. Good luck!
