Hemangioma is a common congenital, vascular disease, most of which occurs in the facial skin and subcutaneous tissues, which not only brings about an impact on people’s appearance, but also poses a threat to their health. Hemangioma is a benign tumor that occurs in vascular tissues, and is formed due to the misshapen, verrucous proliferation of vascular tissues. Most of them appear in infancy, and a few are found in adulthood. Hemangiomas can occur in all parts of the body, and grow on the exposed parts of the face and limbs, which can affect the appearance. Some of them can bleed and get infected repeatedly, and very few of them can develop malignant changes, even life-threatening. Complications of hemangioma include ulcers, bleeding, infection, and nerve root compression symptoms, such as pain, sensory abnormalities, and visual impairment. There are many reasons for the development of hemangioma: genetic factors, women during pregnancy, external environmental pollution, external impact, drug stimulation and adverse factors leading to abnormal proliferation and expansion of the vascular network to form hemangioma. There are many causes of neonatal hemangiomas, and they grow at different speeds, and some of them even disappear automatically. For the sake of children’s healthy and happy growth, parents must pay attention to the growth of neonatal hemangioma and receive treatment as soon as possible.
