Many parents notice lumps on their babies at birth or after birth. These lumps can appear anywhere on the body, but they are most common on the face. There are single bumps and multiple bumps; the color is red and purple; the size is small like a needle point and large like a strawberry; some are flat to the touch and some are long and bulging; some turn white when pressed and some do not respond to pressure; some change in size significantly with body position and some do not; some grow quickly and some grow slowly… …what exactly is this disease? Parents often panic. This kind of mass is what we often call in popular parlance as hemangioma. Hemangioma is the most common benign tumor in infants, with an incidence of about 4-10%, usually more common in girls than in boys, about 3-5 times. They occur more frequently in whites than in yellows and are less common in blacks. The incidence of preterm low birth weight (less than 1 kg at birth) is as high as 25%, while the incidence of twins is also higher. However, medically, Mulliken divided the originally defined hemangiomas into true hemangiomas and vascular malformations based on the biological behavior of the vascular endothelium and the origin of the abnormality. True hemangiomas are formed by abnormal proliferation of endothelial cells, whereas vascular malformations are anatomical malformations that occur without abnormal endothelial cell proliferation. This classification can be a good way to help us solve the question of whether and how to treat hemangioma. Therefore, parents should not panic when they find that their babies have hemangioma, and they should not rush to the doctor. The right treatment path can get the best treatment effect at the least cost.
