Petechiae

Petechiae are small, round, flat, dotted dark red spots caused by hemorrhages in the skin or mucous membrane. Petechiae occur, for example, during purpura. They are small hemorrhages in the upper layers of the skin or mucous membranes.

Petechiae are formed due to damage to small capillaries and the subsequent release of red blood cells into the tissue. The size of petechiae is usually 1-2 mm. They do not disappear with pressure, unlike rashes.

Petechiae can appear in various diseases and conditions, such as thrombocytopenia, endocarditis, sepsis, severe viral and bacterial infections. Petechial rash is especially common with meningococcemia.

Thus, the appearance of petechiae may indicate a serious illness and requires immediate medical attention to determine the cause and prescribe adequate treatment.

Petechiae: what is it and what are its causes?

Petechiae are small dark red spots that form on the skin or mucous membranes and are caused by hemorrhages. They can be single or in groups, range in size from a few millimeters to a centimeter, and do not disappear when pressure is applied to them.

Petechiae can occur for a variety of reasons, but most often they are associated with bleeding disorders or capillary damage. This can be the result of various diseases or physical stress.

One of the most common causes of petechiae is purpura. Purpura is a disease characterized by bleeding in the skin, mucous membranes and other organs. This may be the result of a malfunction of platelets, which play an important role in blood clotting. In this case, blood can leak from the capillaries and form petechiae.

Petechiae can also occur in other diseases such as thrombocytopenia, leukemia, sepsis, meningococcal infection, rheumatoid arthritis, vasculitis, etc. In addition, the use of certain medications such as aspirin and anticoagulants can also cause the appearance of petechiae.

If you experience petechiae, especially if there are a lot of them or they appear regularly, consult your doctor. The doctor will conduct an examination to find out the cause of petechiae and prescribe appropriate treatment.

In some cases, if petechiae are caused by a serious medical condition, hospitalization and special treatment may be required.

In conclusion, petechiae are small dark red spots that can be a sign of various diseases or physical stress. If you experience petechiae, consult your doctor for professional advice and treatment.

Petechiae: Causes, symptoms and treatment

Petechiae (Petechiae) are small round flat dotted dark red spots that are formed due to hemorrhages in the skin or mucous membranes. These spots can appear on various parts of the body, but most often they are found on the skin of the extremities, face, neck and upper torso. The appearance of petechiae can be associated with various reasons and can be a symptom of a serious disease.

One of the main causes of petechiae is a condition called purpura. Purpura is bleeding in the skin and mucous membranes that occurs due to damage to the capillary walls or low platelet counts in the blood. Purpura can be caused by a variety of factors, including thrombocytopenia (low platelet count), infections, autoimmune diseases, vascular disorders, and certain medications.

In addition to purpura, petechiae may be associated with other conditions and factors. Some of these include thrombocytopenic purpura, allergic reactions, bleeding due to damage to blood vessels, infections including meningococcal septic purpura, drug reactions, thrombocytopathies (platelet dysfunction), leukemia and other hematological diseases.

Symptoms of petechiae can vary depending on its cause and location of occurrence. In most cases, petechiae do not cause pain or itching, and they may go away on their own within a few days or weeks. However, if petechiae is accompanied by other symptoms such as fever, rapid heartbeat, weakness, or bleeding from other areas, you should see a doctor to get a diagnosis and determine the cause.

Diagnosis of petechiae usually includes a physical examination, patient history, and laboratory tests. Your doctor may order blood tests to determine your platelet count and check for other abnormalities related to circulation and clotting.

Treatment of petechiae directly depends on their cause. If petechiae are a symptom of an underlying disease, then it is this disease that needs to be treated. For example, if purpura is caused by an infection, then antibiotic therapy or antiviral drugs will be prescribed. Thrombocytopenic purpura may require platelet transfusion or treatment with immunomodulatory drugs.

In some cases, when petechiae are not the result of a serious illness and do not cause discomfort, special treatment may not be required. However, it is important to consult a doctor to find out the cause of petechiae and rule out serious diseases.

In addition to treating the underlying condition, there are some measures that can help prevent petechiae or reduce the risk of petechiae. It is important to avoid injuries and traumatic situations that can damage blood vessels. Regular consumption of foods rich in vitamin C and K can help strengthen the walls of blood vessels and improve blood clotting.

In conclusion, petechiae are small pinpoint spots caused by hemorrhages in the skin or mucous membranes. They can be a symptom of various conditions, including purpura and other hematological diseases. Diagnosis and treatment of petechiae are aimed at identifying and treating the underlying disease, as well as preventing recurrent hemorrhages. If you develop petechiae or are concerned about other symptoms, it is important to see your doctor for professional advice and diagnosis.
