Infantile hemangioma
Infantile hemangioma
Clinical features Infantile hemangiomas (juvenile hemangioma, strawberry nevus) are the most common vascular tumors of the childhood affecting as many as 1/100 births1โ4 By definition the tumors do not present at birth but instead develop within the first weeks of life. Lesions can occur in any cutaneous region, although the head and neck are by far the most commonly involved (Figs 35.465 and 35.466). Females are affected more often than males.
The flat red or purple lesions, frequently less than 5โฏcm in diameter, gradually enlarge and develop a raised surface. Usually they are discrete but (less often) can be large, diffuse and disfiguring. Over a period of months or years, the vast majority involute spontaneously.
