Hemangioma is usually a bright red tumor with clear boundary and unfading color that protrudes from the skin surface, including scalp, palm and foot center. Some hemangiomas also have blue surface, unclear boundary and downward spread. The method of confirmation is mainly through local ultrasound of skin; If the growth site of hemangioma is easy to be rubbed and the growth speed is fast, immediate treatment is needed. Hemangioma is a kind of reticular cavernous tumor formed by gene mutation of fetal blood vessels, abnormal hyperplasia of vascular endothelium and outward growth. When it grows inward, it can become the oppressor that compresses the underlying tissues and organs. Therefore, if it is suspected of hemangioma, the color ultrasound should be confirmed in time.
