Hemangiomas are the most common congenital lesions in children, some of which are true hemangiomas and others are vascular malformations. The incidence is about 3-8%. Hemangiomas can be found in all parts of the body, especially in the skin and subcutaneous tissue, followed by the oral mucosa, muscles, and can also occur in bones, internal organs, brain and other systems. Traditionally, hemangiomas are classified as capillary hemangiomas, cavernous hemangiomas, and trapezoidal hemangiomas. The majority of capillary hemangiomas (70-80%) disappear on their own, but it takes a long time. A larger percentage of patients will not go away and may continue to develop, affecting their appearance or function. Cavernous hemangiomas, as well as trapezoidal hemangiomas, are vascular malformations that do not disappear on their own. The growth of hemangiomas is most gross=apparent in the first three months of life, and then enters the stabilizer phase and regresses. Although hemangiomas are benign and have the potential to disappear on their own, they can destroy surrounding tissue, and some hemangiomas show infiltrative growth, resulting in cosmetic defects in children. In addition it can lead to dysfunction. In rare cases, hemangiomas have the potential to become malignant again. During the growth of hemangiomas, many complications can occur such as ulceration, bleeding, infection, etc., even endangering the life of the child. The diagnosis of hemangioma is generally not difficult, but its treatment is still not completely solved, especially large cavernous hemangioma and arterial hemangioma are still a big problem in medicine. For hemangiomas that have shown improvement, continued observation should be taken, and on the contrary, early intervention should be made. For cavernous hemangioma and all kinds of vascular malformations, early intervention should be active. Because there are still many shortcomings in the research of hemangioma, resulting in many defects in the treatment of hemangioma, it is very important to actively adopt individualized treatment in the treatment of hemangioma.
