Hemangiomas are most commonly seen in infants and young children in the skin of the mouth, face and neck or oral mucosa. The course of the disease can be divided into a proliferative phase, a regressive phase and a regressive completion phase. The proliferative stage is usually around 4 weeks and 4 months of age. The regression phase usually begins after the age of 1 year, with more than half of the children completely regressing within 5 years, and the regression is complete around the age of 10 years. In view of the fact that after the regression of hemangioma, some children may be left with local sequelae such as hyperpigmentation, scarring and skin laxity. Therefore, when a hemangioma is detected, one should consult a doctor in time and choose an appropriate individual treatment plan according to the different cycles and changes of the hemangioma in order to minimize the sequelae. For the treatment of hemangioma in infants and young children, it needs to be judged according to the age of the child and other comprehensive judgment. The current treatment methods mainly include oral medication, local sclerosing agent injection or dressing, etc., all of which can receive good results. It is worth noting that no matter drug treatment or sclerotherapy and other treatments, they must be used and treated under the guidance of experienced doctors.
