Infantile hemangiomas are benign tumors characterized by the proliferation of vascular endothelial cells, with a prevalence of 3%-4% in children. Hemangioma involves growth, so it is important to grasp the principle of early diagnosis and early treatment. Its growth is characterized by a growth spurt from 3-6 months, slowing down after 6 months, stabilizing or even entering a receding phase after one year of age, and the receding time often lasts about 3-6 years. For treatment, there are various methods. For superficial hemangiomas, they can be treated with topical drops and laser. For deeper hemangiomas, they can be treated by local injections, surgery and other methods.
