They are the most common soft-tissue tumors of infancy. The appearance of hemangiomas is defined by the lesion’s depth, location, and stage of evolution. A superficial hemangioma lies in the upper dermis and often originates as an erythematous macular patch, a pale macule, or a localized telangiectasia with a pale halo. The lesion grows and becomes vascularized during the first 2 months of life. The classic presentation is a bright red, slightly raised, noncompressible plaque. It commonly regresses by 2 to 3 years of age but may persist throughout life. Hemangiomas can also affect the airway, eyes, and liver or cause high-output cardiac failure if sufficiently large. The most important local complication is ulceration, which can be exquisitely painful. The differential diagnosis includes vascular malformations, malignant vascular neoplasms, pyogenic granulomas, and giant melanocytic birthmarks.
