I just went to Answer.com and this is what I found.
[quote]A petechia (IPA pronunciation: [pə'tiki.ə]), plural petechiae (IPA pronunciation: [pə'tiki.aɪ]) is a small red or purple spot on the body, caused by a minor hemorrhage (broken capillary blood vessels).
Petechiae are a sign of thrombocyt
openia (low platelet counts),
Petechiae in adults should always be quickly investigated. They can be interpreted as Vasculitis, an inflammation of the blood vessels, which requires immediate treatment to prevent permanent damage. Some malignancies can also cause petechiae to appear. In anyone over eighteen, petechiae should be investigated by a physician within a day or so to rule out the more dangerous conditions. Dermatologists can be the most helpful specialists in these conditions, because they can more easily identify if the condition is petechiae or some similar looking but less worrisome rash.
Also, at Medline Plus:
[quote]Petechiae are pinpoint-sized red dots under the surface of the skin (petechial rash). The dots are red because they contain blood that has leaked from tiny blood vessels (capillaries) into the skin. A petechial rash isn't a disease but a sign of an underlying problem that requires further evaluation. Petechiae can occur anywhere on the body.
A low platelet count (thrombocyt
openia) is a common cause of petechiae. Platelets play an important role in blood clotting. Causes of a low platelet count include:
* Autoimmune disorders, such as lupus or rheumatoid arthritis
* Viral infections, such as mononucleosis and measles (rubella)
* Side effect of certain medications, such as chemotherapy drugs
* Bone marrow disorders, such as leukemia
Treatment of petechiae depends on the underlying cause. If you develop a petechial rash, see your doctor promptly.Sorry I couldn't be more helpful.
Each day is a gift, make every one count.
