Haemangiomas are benign tumours of the blood vessels. They are among the most frequent causes of consultation in children all over the world. Haemangiomas may result from vascular malformations or vascular proliferation. The most common vascular malformative haemangiomas are the mediofrontal and occipital haemangiomas of infants (stork bites) that spontaneously regress during childhood and the so-called port-wine stain, while the most frequent vascular proliferative haemangioma is the immature capillary haemangioma or strawberry haemangioma. Strawberry haemangiomas usually appear shortly after birth, grow rapidly for several months, sometimes ulcerate without bleeding, and spontaneously regress. Most strawberry haemangiomas only reach a few centimetres in diameter, but occasionally they may involve large areas of the skin. On the face, they may compromise sight, smell or taste.
Small haemangiomas should only be observed. If ulceration occurs, a mild antiseptic solution such as methylrosanilinium chloride (gentian violet; see Methylrosanilinium chloride) should be applied topically to prevent secondary infection. Patients with rapidly growing or large haemangiomas should be referred to a secondary- or tertiary-level health centre for evaluation and treatment.
