Nowadays, along with environmental pollution, food and drugs, hemangioma has become more common in recent years. As parents of children do not understand this disease, it often leads to misdiagnosis and delays the best treatment time for their children, thus adding difficulties to the later treatment and bringing great harm to the normal health of children, affecting their normal development and growth. Hemangioma is a benign congenital tumor that can occur in any part of the body, with skin and oral mucosa being the most common. The face, neck and extremities are the most common sites, while muscles, bones and internal organs are less common. There is no clear cause of hemangioma, and it is more common in female than male infants. In the past, hemangiomas were classified into: capillary hemangioma, cavernous hemangioma, mixed hemangioma, trapezius hemangioma , and the old classification is not helpful for the diagnosis and treatment of hemangioma. Now, according to the new classification drawn up by the International Society for the Study of Vascular Diseases, hemangiomas are mainly classified into: hemangiomas and vascular malformations. According to the new classification, hemangiomas are seen in infants and young children, mostly as mosquito bites or pinpoint red dots, or they may be flaky at birth. Most expand peripherally within the first few months of life; growth can be rapid or slow, with some children presenting as multiple, generalized lesions. Early intervention may be needed if the growth is rapid or if the hemangioma is around the eyes, mouth, or nose. This is to prevent irreversible effects on physical appearance. In addition, there is a special case of infantile hemangioma, namely Kaposi’s syndrome, which is associated with a decrease in platelets, and the child may experience severe bleeding, which must alert parents. Once this type of disease is considered, it must be diagnosed and treated early. Vascular malformations mainly include capillary malformations, venous malformations, and arteriovenous malformations. 90% of them exist at birth, but they may have no clinical signs and grow with age later and do not fade away on their own. 1.Venous malformations are soft subcutaneous masses with unclear borders, which can be reduced after squeezing and can present blue, dark red or purple lesions under the skin. 2.Wine colored spot: it is a flat and less elevated plaque, pink, flat, clear boundary, fading with pressure, darkening, reddening and purple with age. 3. Arteriovenous malformation: It shows that there are thick and pulsating blood vessels in the area around the hemangioma in the shape of candles or cords. The surface temperature is higher than normal skin, and continuous tremor can be palpated and continuous wind-like murmur can be heard locally. Treatment: A combination of medication, surgery and laser treatment can be considered for both hemangioma and vascular malformation. Experts suggest that “individualized” treatment plans should be adopted according to different types, periods, ages, locations and growth characteristics of hemangiomas.
