Hemangioma is a common benign congenital tumor in infants and young children, with high morbidity rate. Foreign countries report that the morbidity rate of newborns is about 2%~3%, and the morbidity rate of infants within 1 year old reaches 10%. The incidence rate of preterm and low-birth-weight infants is even higher, reaching 20%; the etiology and pathogenesis of hemangiomas are unknown so far, and they can occur in any position of the body, such as the head, face, neck, limbs, body, etc., and even the internal organs. Some people have multiple hemangiomas in various parts of the body at the same time. Most hemangiomas grow on the skin and look dark red and wrinkled like strawberries, so some people call them “strawberry hemangiomas”. A typical “strawberry hemangioma” is not very obvious at birth, or is just a small red dot, as if it were a rash or a mosquito bite. It slowly appears or gets bigger with age, usually changing the most rapidly at 4 to 5 months, and becoming the largest at 6 months, which is when parents are most nervous about going to the doctor. Another characteristic of this type of hemangioma is that there is a distinct period of proliferation (usually the first five months to one year of age) and a period of natural regression. This strawberry hemangioma is pathologically classified as the so-called capillary type, which belongs to the true tumor type of hemangiomas, and most of them are composed of proliferating capillary endothelial cells. Since capillaries are very small, blood flow in them is slow, so embolism may occur, and some hemangiomas are self-committed due to embolism and ischemia. Capillary hemangioma mainly affects the appearance, but it may affect the function if it grows in more important parts, such as in the eyelids, it may affect the eye closure; if it grows in the nostrils or the respiratory tract, it will affect the respiration; in the mouth, it will affect the eating; in the anus, it will affect the defecation. Some hemangiomas also grow in the muscles, internal organs, and inside the skull, and their symptoms are highly dependent on their location. In addition to affecting the appearance, larger hemangiomas may cause heart failure due to high blood flow, which may result in overloading the heart; they may also destroy platelets, causing low platelets and bleeding. The classification of hemangioma, in addition to the common true tumor-like hemangioma, there are also vascular malformations, which include vascular malformations and lymphatic malformations, and color Doppler and MRI examinations are of great help in diagnosis. The latter, unlike tumor-like hemangiomas that go away on their own, usually require surgical removal to cure. Treatment of hemangiomas depends on size, location, age and type. Tumor-like hemangiomas must be watched intensively because they change rapidly and dramatically in the first few months. Hemangiomas that grow in important areas, such as the face, face, eyelids, mouth, anus and genitals, must be treated early for a favorable outcome. If it affects the vision or seriously affects the appearance, or affects other functions, it must be treated aggressively. As for vascular malformation type hemangioma, since its development law is to develop with age for life, and the older the age, the faster the development speed, so it should be treated as early as possible from the development law of this type of hemangioma itself, but its treatment generally requires surgical resection, which requires that at the same time to consider the patient’s tolerance to the surgery, and the younger the patient is, the lower the tolerance to the surgery is. Considering these two factors, the timing of treatment of this kind of hemangioma should be as early as possible according to the specific situation when the patient can tolerate the surgery, and it is generally advocated that the treatment can be carried out after the age of 1 year.
