Infantile haemangiomas are soft, raised swellings on the skin, often with a bright, red surface. They are a non-cancerous overgrowth of blood vessels in the skin. They are commonly known as 'strawberry birthmarks', 'strawberry naevi', or 'capillary haemangiomas'. They occur in five per cent of babies, with the majority appearing within the first few weeks of life, and reach their full size at about three to six months of age. The vast majority are uncomplicated and will shrink on their own by five to seven years of age and require no further treatment. However, some infantile haemangiomas may occur in high-risk areas (such as near the eyes and nose which can result in impairment to vision and airway obstruction, respectively) and some of them are disfiguring and psychologically distressing to the children and their parents. Some may also develop complications so early medical treatment may be necessary. Corticosteroids are currently the standard treatment; however, it is not known which of a variety of treatments is best.
