At present, there are many inappropriate concepts and classifications of hemangioma in China, which are divided into two categories abroad: tumor and vascular malformation. Tumor type hemangioma is the most common and best treated type of hemangioma, which has a typical process of occurrence, development and regression (generally speaking, the growth period is within one year old, and the growth is fast in the first few months of the growth period, and the older the child is, the slower the growth of the tumor is. After one year of age, the growth gradually stops and the tumor gradually disappears. In general, these tumor-like hemangiomas will eventually recede, but if they are left to develop naturally without treatment, the final outcome will be different, because the severity of the disease varies and the speed of development varies. However, most of the complications do not occur, but the enlargement and thickening of the tumor makes it difficult to recede in the future, and leaves cosmetic defects such as scars, skin folds, pigment residues, etc. after receding. Therefore, we advocate early treatment during the growth phase of hemangioma, so that it can stop growing as soon as possible and turn into the receding phase, in order to achieve the effect of elimination and more beautiful as soon as possible. Urea is a normal metabolic product of human body, which is effective and has few side effects. This type of hemangioma should not be treated with surgery, freezing, isotope, hormone, etc. to avoid adverse consequences; vascular malformation (domestic called cavernous hemangioma, mixed hemangioma, etc.) is congenital. In principle, surgical treatment is required for complete cure (we usually treat with local urea injection and sclerotherapy before surgical excision), and other treatment methods are difficult to achieve ideal treatment effect (or even effective). The timing of surgical treatment should be determined by considering the specific condition, location, treatment effect and other factors.
