Hemangioma is a congenital malformation of the vascular development that can grow anywhere in the body, including the surface of the body and substantial internal organs. With the development of industrial society and the aggravation of environmental pollution, the incidence of hemangioma increases year by year, and patients with this disease are seen in every outpatient clinic. As a congenital disease, the cause of hemangioma is not completely clear, but most studies tend to suggest that too much estrogen is produced in the body of the child and that the liver of the newborn is weak in inactivating estrogen, leading to increased levels of hormones in the body and eventually leading to the disease. There may also be a relationship with environmental pollution. Capillary hemangioma: It can be divided into erythematous nevus (not higher than the skin surface, composed of abundant mature capillaries in the superficial dermis) and strawberry hemangioma (protruding from the skin surface, mainly composed of sinusoidal expansion of capillaries in the deep dermis); erythematous nevus is mostly on the face, but there are also those located on the trunk and extremities, which do not continue to develop after birth and exist for life, and most of them are asymptomatic, but with the growth of age, the color Most of them are asymptomatic, but as they grow older, their color gradually darkens, which affects their beauty and can cause distress to the patient’s heart. In a few cases, if the hemangioma grows in the facial area innervated by the ophthalmic branch of the trigeminal nerve, it may be accompanied by hemangioma in the temporal and occipital lobes, which may lead to epilepsy. Strawberry hemangioma has the highest incidence and can be found between birth and a few weeks after birth as a red spot that gradually increases in size and rises above the skin surface. It can fade gradually between 1-4 years of age, but there are also reports of patients who did not fade until adulthood, and can be left untreated. The affected area may feel heavy and sore. 3.Mixed capillary hemangioma: also known as capillary spongy hemangioma, it grows rapidly in the first 6 months after birth and can reach a large area, and is extremely invasive. As a result, dysfunction of breathing, eating, vision, hearing, etc. may occur. Large hemangiomas often retain and consume large amounts of hemangioma, coagulation factors and fibrinogen, resulting in disseminated intravascular coagulation, which is known as Kasabach-Merrit syndrome. 4.Tracheal hemangioma: It is caused by congenital malformation of blood vessels with multiple small multivessel fistulas, and tortuous and curved vascular pulsations can be faintly seen under the skin, and strip-like dilated vessels can be palpated.
