Petechia - red dots on the face

Petechiae are spotted hemorrhages in the mucous membranes or skin. As a result, small spots are formed, the diameter of which is about two millimeters. This phenomenon is due to the fact that red blood cells penetrate the walls of the capillaries.

When the disease is just beginning, these points have a bright red color. Over time, they brown. Such formations are at the same level with the skin and are not palpable. From petals, petechiae differ in that they do not disappear when you press them with your finger.

Petechia can look like red dots on the face. They can appear in typhus, purpura, septicemia, smallpox, verhlophic disease, scurvy. When examining patients with these diseases, red dots on the face were always observed, which had a pink color and did not disappear after pressing with a finger, and after a time they acquired a brown color.

Petechias are primary and secondary. At primary red currents on the face disappear after a few days. First, their outlines become blurred, the color dims, and then they completely cease to be visible.

Sometimes the red dots on the face can acquire a greenish tinge and become covered with pus with pus. This is typical for recurrent fever and is rare.

The size of the petechiae is smaller than the rose-osseous spots, and do not appear so intensely. Sometimes the red dots on the face of a child can be mistaken for insect bites. But an experienced doctor immediately recognizes petechiae. They are accompanied by a hemorrhage of the vessels in the skin without ruptures, so often such a symptom is not taken into account.

Secondary petechiae are characterized by the fact that blood cells leak into adjacent tissues. This phenomenon does not disappear if you press your finger. Thus, the roseous stains always turn into secondary petechiae. People of all ages can suffer from this phenomenon. Getting rid of petechiae is as easy as getting rid of pores on your face, it will not work if they do not go away by themselves. In this case, only surgical intervention will help.

This procedure is of a cosmetic nature and can not give a complete guarantee of excluding the reappearance of petechiae.

Most often, petechiae appear due to injuries and strokes. On the face they can arise because of a strong cough, vomiting. This is quite common in children. To serve as the reason for the appearance of red spots can also be strong pressure, the laying of a tourniquet. In these cases, petechiae pass alone for a few days. They are not a symptom of the disease and are not dangerous to health.

However, in some cases, petechiae can talk about thrombocytopenia. This condition may be due to the taking of specific drugs or the presence of an infection in the body.

Red spots can also form due to blood clotting disorders. Such diseases as systemic lupus erythematosus, rheumatoid arthritis, Ehlers-Danlos syndrome, Wegener's granulomatosis, infective endocarditis, periarteritis, hypercorticism, scurvy may also be accompanied by the appearance of petechiae.
