Abstract
Infantile hemangiomas (IH) are the most common tumor of infancy and have been estimated to occur in 4% of infants. While IH are typically absent at birth, they become noticeable within the first few weeks of life. Approximately one third of IH present shortly after birth, another third present in the first month and the remainder develop within the first six months of life.
Key words: infantile hemangiomas, tumor, lesions, vascular patches.
