Hemangioma consists of a large number of proliferating blood vessels and is a common congenital soft tissue tumor in children, with an incidence rate of about 1% to 2%. Most hemangiomas are found in infants and children after birth. The development of hemangioma can be generally divided into three phases: 1, proliferative phase: after birth, hemangioma keeps proliferating and expanding, and rapidly invades to the surrounding skin and deep tissues, and the general time of proliferative phase of hemangioma is 6 to 10 months. 2.Stabilization period: the growth rate of hemangioma is gradually slow, with the growth of young children, the hemangioma grows slowly, but the growth rate is still faster than the growth of children, the proliferation and degeneration of hemangioma alternates, the general time is 3～6 months. 3.Degeneration period: Generally, the growth rate of hemangioma will be slowed down after 1 year of age, some capillary hemangiomas will begin to degenerate, and the fibrous fat tissue inside the hemangioma will increase, and a small number of children can be completely degraded when they are 5 years old. In the process of degeneration, the color of capillary hemangioma changes from purplish red or deep red to light purplish red, and then the color gradually becomes lighter to grey, and the shape changes from full and bulging to flat and wrinkled, and the skin tissue is fibrotic. After the regression of hemangioma, capillary dilatation and pigmentation may remain in the skin at the lesion, and generally no scar is left. Cavernous hemangiomas regress very slowly and only a very small number of children can regress naturally, while the vast majority of cavernous hemangiomas do not regress naturally. Most mixed hemangiomas, trapezoidal hemangiomas, orange-red spots, wine-colored spots and other hemangiomas will not subside naturally. Only some strawberry hemangiomas and capillary hemangiomas can subside naturally within 5 years of age, and very few of those over 5 years of age subside completely. For infants and young children with hemangioma, the type of hemangioma, site of occurrence, surface color, morphology and size, the extent of lesion involvement, whether it is higher than the skin, etc., should be recorded in detail according to the size of the measurement with a planogram, and generally reviewed once a month. If the growth rate of hemangioma is too fast (sometimes capillary hemangioma can grow 1~2mm per day), the patient should be re-examined once a week, and the result should be compared with the last examination. If the scope of hemangioma lesion is reduced, the color of the surface becomes lighter, and the height of the skin elevation is flattened, it means that the hemangioma lesion is in the period of stabilization or regression, so the patient can continue to wait for the regression under observation. If the scope of hemangioma is enlarged, the surface color is dark purple or dark red, and the skin elevation on the surface is aggravated, it means that the hemangioma is in the proliferative stage, and active treatment measures should be taken. If the hemangioma lesion is in the head, face, hands and feet and grows rapidly, special attention should be paid to it, and it should be treated in time, so as not to lose the best time for treatment when it grows too big, resulting in facial deformity or limb disability. There are many kinds of treatment methods, such as laser, freezing, surgery, injection of anticancer drug “pingyangmycin” into the tumor, and nuclear medicine beta-ray dressing treatment, etc. Comparatively speaking, nuclear medicine beta-ray dressing treatment may be the best choice.
