Keep looking.: Purpura is the result of blood leakage into the skin. It may represent a relatively benign condition or herald the presence of a significant underlying disorder such as low platelet levels, coagulation factor deficiencies, or a vascular defect. Testing should be continued until the cause is found, particularly if fever is also involved. ...Read more

Are single petechiae spots (not clusters) worrisome? I have 3 tiny (1mm) pink ones - 1 on thigh, 1 on buttock, 1 on lower leg. No bruises

Are single petechiae spots (not clusters) worrisome? I have 3 tiny (1mm) pink ones - 1 on thigh, 1 on buttock, 1 on lower leg. No bruises

Watchful waiting: What you described is not worrisome, however it is worth watching, i.e, keep an eye on such lesions to see if more are developing. At your next visit to your doctor you should ask her/him to look at the lesions, if any are present at the time. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex. ...Read more

Causes for Petechiae with platelets at 331? Occasional petechia spots on chest and legs... Diagnosed but doctor doesn't know what it could be

Causes for Petechiae with platelets at 331? Occasional petechia spots on chest and legs... Diagnosed but doctor doesn't know what it could be

Petechia normal CBC: Occasionally no cause can be found, in these cases is Indicated to perform: a "platelets function assay" as well request a capillary function, but the patient are very symptomatic.
Petechia refers to one of the three descriptive types of bleeding into the skin differentiated by size, the other two being purpura and ecchymosis. Petechiae are by definition less than 3 mm.
The term is almost always used in the plural, since a single lesion is seldom noticed or significant.
The most common cause of petechiae is through physical trauma such as a hard bout of coughing, holding breath, vomiting or crying, which can result in facial petechiae, especially around the eyes. Petechiae in this instance are harmless and usually disappear within a few days. Petechiae may be a sign of thrombocytopenia (low plateletcounts) when platelet function is inhibited (e.g., as a side effect of medications or during certain infections), or in clotting factor deficiencies.[1] They may also occur when excessive pressure is applied to tissue (e.g., when a tourniquet is applied to an extremity or with excessive coughing or vomiting).
If unsure, petechiae 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. Petechiae should be investigated by a doctor to rule out the more dangerous conditions.
The significance of petechiae in children depends on the clinical context in which they arise. Petechiae in children can occur with viral infections. In this instance, they do not necessarily signify a serious illness. However, they are a hallmark signal of some potentially serious illnesses, such as meningococcemia, leukemia, and certain causes of thrombocytopenia, of which meningococcemia can cause death within 48 hours of infection. Therefore, their presence should not be ignored.
Petechiae (in the face) may also be present in cases of asphyxiation. ...Read more
