Subcutaneous hemorrhage on the child's face

There are subcutaneous hemorrhage spots on the child's face, which is mainly caused by rupture of capillaries. There are many causes, including medication and allergies. For example, mosquito bites often lead to such symptoms. Of course, we should also pay attention that allergic purpura can also cause such symptoms. Children's subcutaneous bleeding must be taken seriously and go to the hospital for examination in time.

Subcutaneous hemorrhage on the child's face

The main cause of subcutaneous bleeding is damage to the blood vessel wall, which causes blood to seep out of the blood vessel. The diameter of the bleeding spot is 3-5 mm, which is called purpura. Diseases that cause purpura include allergic purpura, allergic purpura caused by sulfa drugs, and allergic purpura after insect bites is also common. The elasticity of blood vessels in the elderly decreases and their fragility increases, so even a slight collision will cause subcutaneous bleeding.

Young women often have purpura, which disappears on its own without treatment. The cause of purpura is unknown. Any other factors that increase the fragility of blood vessel walls can cause subcutaneous bleeding, such as bacterial or viral infection, malnutrition, vitamin C deficiency, and rare hereditary hemorrhagic telangiectasia. In addition to the above-mentioned vascular damage factors, it is also related to thrombocytopenia or poor platelet quality.

There are many diseases that cause changes in platelet quality, such as idiopathic thrombocytic purpura. It can also be caused by lesions in the hematopoietic bone marrow depot, such as aplastic anemia, leukemia, and myeloma. Physical and chemical factors destroy the megakaryocytes that produce platelets, such as radiation, anti-cancer chemotherapy, etc.

What to do if a child has subcutaneous bleeding on his face

What should you do if a child has subcutaneous bleeding on his face? First, you need to find out the cause. If the situation is serious, it is best to go to the hospital for a routine blood test.

In daily life, we often find "black and blue patches" on the body surface, which are medically called purpura. This is a sign of subcutaneous bleeding. This bleeding can be like a pinhole, called a petechiae; it can also be a large area, which is the overflow of blood in the blood vessels. The color is bright red at first, and turns into yellow-brown old bleeding after 2-3 days. Petechiae, purpura and ecchymosis all indicate subcutaneous bleeding, but the amount of bleeding and the size of the bleeding range are different. If subcutaneous bleeding is accompanied by significant swelling of the skin, it is called hematoma.

When children have subcutaneous bleeding on their face, they should pay attention to their platelet count, especially bleeding spots caused by thrombocytopenia and the possibility of diseases such as scurvy. It is recommended to further check the platelet count and coagulation time. Pay attention to avoid fatigue, eat more vegetables and fruits, actively supplement vitamin C, and seek further examination when necessary.
