Laser use in infantile hemangiomas, when and how.

Infantile hemangiomas (IHs) are proliferating embrional tumors which can stem from placented tissue and are constituted by endothelial cell hyperproliferation. The management of the IHs is always challenging for all the specialists because of the heterogeneous behavior of these lesions. The factors leading to an aggressive position are essentially these: the prevention or reduction of aesthetic risks, the prevention or treatment of ulcerated hemangiomas, the prevention or impairment of functional risks and pain, and the removal of life-threatening risks. The treatment of vascular lesions is one of the mostly sought and performed cutaneous laser procedures, and in the field of IH treatments the more used laser devices certainly are pulsed dye lasers. Early laser therapy is able to reduce the possibility that the lesion will reach its full size, preventing several complications, connected to the hemangioma's growth, and providing psychological relief for pediatric patients and their parents.
