The scientific name for hemangioma is strawberry hemangioma, also known as capillary hemangioma or simple hemangioma. They usually appear less than 1 month after birth and are often small at first, but then grow and expand rapidly to become bright red or purplish-red patches that are round, hemispherical, lobulated or irregularly shaped, with a surface like a strawberry, which is how strawberry hemangioma got its name. Hemangiomas can grow very large, and large hemangiomas can even cover one side or an entire limb. This rapid growth consumes a lot of oxygen, resulting in necrosis and ulceration of the hemangioma itself due to lack of oxygen, causing tissue destruction and even perforation of organs such as the nose and ear in severe cases. However, after the child is 1 year old, the hemangioma will enter the receding stage, when white streaks appear in the middle of the hemangioma, the pale area gradually expands, and the tumor gradually shrinks and slowly disappears, a process that usually takes several years. When many parents find out that their child has strawberry hemangioma, they are eager to get treatment, but not all hemangiomas need to be treated. So when should hemangioma be treated? And how should they be treated? For children under the age of one, early treatment is generally recommended to stop the growth of hemangioma, prevent spontaneous ulcers and damage to organs (such as the eyes and nose), and promote early regression of the hemangioma. The main means of treatment are lasers and drugs. Pulsed dye laser (wavelength 595nm) and long pulse width Nd:YAG laser (wavelength 1064nm) are very effective lasers with few side effects as their advantages; in many cases, after 4-5 treatments, the growth of hemangioma can be stopped. Oral glucocorticosteroids are also a major treatment for hemangioma. The dose should be measured according to the child’s weight and should be taken for 6-8 weeks, which can shrink most of the hemangiomas. The dose is also measured according to the child’s weight and is very effective, but may cause adverse reactions such as lower blood pressure and slower heart rate in children, so hospitalization is required for observation. For severe uncontrollable hemangiomas, laser and drugs can also be combined to take advantage of the combined treatment. For children over the age of 1, hemangiomas have basically stopped growing and have entered a receding phase, at which point they can be dynamically observed and wait for them to recede on their own. Of course, if you want them to recede faster at this point, you can also give some laser treatment. Finally, it is worth mentioning that hemangiomas are easily confused with some other vascular malformations, and the latter are sometimes referred to generically as hemangiomas, but their nature and treatment are different, so a correct diagnosis is important.
