The exact cause of vascular tumor of skin is not always clear, but they are thought to result from abnormalities in the development of blood vessels during fetal growth. There are two main types of vascular tumors: infantile hemangiomas and vascular malformations. Infantile hemangiomas typically appear shortly after birth and grow rapidly, reaching their peak size at around 1 year of age before gradually shrinking and often disappearing by adolescence. Vascular malformations, on the other hand, are present at birth and tend to grow proportionally with the child and may not regress on their own.
