The common benign skin tumors in childhood are hemangiomas, such as nevus of bright redness (also known as capillary dilatation nevus), strawberry hemangioma, and cavernous hemangioma. They are large red or greenish-red patches, several bright red soft lobulated tumors above the skin surface, and large lobulated purple-red soft subcutaneous masses, respectively. The bright red nevus can often fade on its own if it occurs in the middle of occipital area and forehead, while other parts gradually expand and deepen without natural fading. However, clinically it is difficult to estimate whether the hemangioma will recede naturally or not. Will the hemangioma continue to grow? In addition, the current pulsed dye laser treatment for hemangioma is less painful and has fewer side effects, does not leave scars, and can be safely used for infants and children who are only about 10 days old, and the cost of treatment is proportional to the size of the lesion and the pain time is less.
