Hemangioma is the most common benign tumor in infants and children (the incidence of infants and children is 1%-2%, and the ratio of male to female is about 1:3), and is almost always found from birth to shortly after birth. Hemangiomas are most frequent on the head and face, with the rest on the limbs, trunk, and internal organs. Depending on the depth of distribution of the lesion, there are different signs and symptoms, and the more superficial ones (located in the papillary layer of the dermis) are often called “strawberry hemangioma”; those involving the deeper dermis, subcutaneous or intramuscular layers are often called “spongy capillary hemangioma”; when both exist together, they are called “mixed hemangioma”. When the two exist together, it is called “mixed hemangioma”. Vascular malformations are present at birth. Capillary malformations are often obvious at birth, while arterial and arteriovenous malformations are often not obvious in infancy (trabecular hemangioma). Vascular malformations have no natural fading characteristics during the growth of children, and can gradually worsen. 1.Capillary malformation (nevus): it is patchy, and the damage can be hypertrophic with age, and the surface is nodular and warty. 2, venous malformation: belongs to low-flow vascular malformation, manifested as a lump under the skin or mucous membrane or a purple-blue surface, mild vascular filling, varicose veins, easily compressed, changing with the change of body position (such as low hanging, crying or struggling to increase), soft texture, there are often venous stones within the lump, and emboli can be palpated.
