The concept of hemangioma is a benign tumor that occurs in the vascular tissue and is formed due to the misshapen, tumor-like proliferation of vascular tissue. It is most common in children, with an incidence of about 1%-2%, of which 70%-90% are seen in newborns <1 month of age. The incidence is up to 23% in premature infants. Girls are more common than boys, about 5:1, and most hemangiomas are solitary, but about 1 in 5 cases are multiple. There are two types of hemangiomas, primary and secondary, of which primary accounts for 75% and secondary for about 25%. Most secondary hemangiomas appear in infancy, but a few are found in adulthood, and the cause is unknown. Primary, or congenital fetal, hemangiomas are formed by the proliferation of the vascular network during embryonic life and are present at birth. Hemangioma can occur in all parts of the body, and can affect the appearance of the face and exposed parts of the limbs. They can affect the appearance of the face and the exposed parts of the limbs. They can compress and destroy the function and shape of the surrounding tissues and organs to varying degrees, and affect the growth and development of the body. Some can repeatedly bleed and become infected, and in a very small number of cases, they can become malignant and even life-threatening. The common clinical classification is according to its structure: (1) Capillary hemangioma: Mostly seen in female infants, red dots or red spots on the skin are seen at or after birth, gradually increasing in size and elevation, with clear boundaries, fading when pressed, and returning to red after relaxation. (2) Spongiotic hemangioma: It is mostly found in the subcutaneous tissue, but also in the muscles, showing local elevation or muscle hypertrophy, and the surface may be blue-purple and the limbs are tense. (3) Trapezius hemangioma: Besides occurring in subcutaneous and muscle, it often infiltrates into bone tissue and has a larger scope, even more than one limb, with obvious compressibility and swelling sensation. The harm of body surface hemangioma 1, affect the beauty, body surface hemangioma can occur in all parts of the human body surface, but the jaw, neck, trunk, limbs and other parts of the common, because its color is mostly red, black, green and irregular shape or convex, or varicose, or sinuous, etc., seriously affect the beauty, causing great harm to patients physically and mentally. 2.Affected by external impact and pressure, causing hemorrhage resulting in more blood flow. 3.Destruction of the surrounding tissues, causing deformity and affecting the function. 4.Affect the growth and development of bones. 5.Ulceration of the tumor body occurs. 6.Serious deformation of limbs. 7.Heredity to the next generation. Hazards of visceral hemangioma (hepatic hemangioma is common): 1.When the tumor gradually increases or compresses the stomach and intestines, it causes upper abdominal discomfort, bloating, abdominal pain, nausea and other symptoms, and in serious cases, it leads to deformation of normal organs such as spleen and stomach of patients and destroys their functional forms. 2.Large hemangioma located on the surface of liver may rupture by itself, causing abdominal hemorrhage and endangering life. 3.It can be transformed into malignant hemangioma. 4.Pain in liver area and psychological stress. Diagnosis of hemangioma 1.Characteristics of tumor appearance (wine-spotted or prune-like, etc.). 2.Discoloration or shrinkage by pressure. 3.positive postural meta-test, palpation and venous stone, puncture and extraction of coagulated whole blood (sponge type), palpation with pulsating sensation, auscultation with wind-like murmur, pressure closure of blood supply artery and murmur disappearance (trapezoid type). 4.Angiography shows contrast concentration or vascular malformation in the tumor area. 5.Pathological histological examination to confirm the diagnosis. Treatment of hemangioma (early treatment of hemangioma is recommended, the earlier the treatment, the better the efficacy and prognosis) 1.Sclerotherapy: Sclerosing agent is injected into the hemangioma to make it shrink and disappear. This method is simple and easy to implement, and the efficacy is exact. 2.Cryotherapy: applying liquid nitrogen freezing technology can make capillary embolism and tumor shrink. 3.Microwave heat-transfer therapy: Applicable to sponge type hemangioma. 4.Hormone therapy: applicable to a wide range of capillary hemangioma. 5.Embolytic therapy: Interventional technology is used to inject sclerosing agent into the hemangioma. 6.Radiation and isotope posting: It is no longer used due to the late effects on the children and environmental hazards. 7.Surgical treatment: It is possible to remove the hemangioma simply by surgery, and larger hemangiomas can also be embolized by intervention and then removed by surgery.
