There are many small red spots on the child's legs

Parents are very worried when their children have many small red spots on their legs. There are many reasons why children have many small red spots on their legs. If there are no special symptoms, don’t worry about it, the red spots will slowly disappear. If the fever persists, it should be taken seriously. If a child has many small red spots on his legs, it may be caused by leukemia. It is best to go to the hospital for a check-up. Also, be careful not to let your child come into contact with substances that may cause allergies.

The reason why children have many small red spots on their legs

1. Allergic purpura: If a child has many small red spots on his legs, the first disease to be considered is allergic purpura. Experts point out that the lower limbs of the human body are a high-incidence site for allergic purpura, especially children are more susceptible to this disease. However, the red spots caused by allergic purpura are mainly bright red in color at the beginning, and will fade after pressing. They may be accompanied by mild pain symptoms. As time goes by, they will gradually darken, turn yellow and disappear. If not treated in time, these red spots will reappear.

2. Leukemia: When small red spots appear on children's legs accompanied by nose bleeding, bleeding gums, and recurrent fever, symptoms of acute leukemia should be considered. This is mainly because children with acute leukemia have reduced coagulation factors, abnormal and reduced platelet function, which can lead to capillary bleeding throughout the body, thus manifesting as red spots and bruises on the skin. Once this happens, you need to go to a regular hospital for examination and treatment in time.

3. Mosquito bites: Some children will not develop hard lumps on their legs after being bitten by mosquitoes, but small red dots will appear. Especially when the weather is hot, the number of mosquitoes in the environment increases, and they will be bitten by mosquitoes if they are not careful. If a child's skin only develops a small red dot after being bitten by a mosquito, it is generally not accompanied by itching symptoms, so special treatment is usually not required.

Testing for childhood leukemia

It mainly includes blood picture, bone marrow picture, immunohistochemical staining, bone marrow cell immunotyping, leukemia fusion gene detection, IgH and TCR gene rearrangement detection, chromosome karyotype analysis, etc.

Imaging examinations. Abnormal changes in blood test data show that most children have leukocytosis, ranging from tens of thousands to hundreds of thousands, and significant proliferation of bone marrow leukocytes. In a few patients, the white blood cell count may be reduced. The proportion of immature cells in the classification varies depending on the time of consultation and the typing, and even immature cells cannot be detected in the blood picture.
