Nevus erythematosus: commonly known as red birthmark, its lesion area is the dermis layer of the skin, seldom invades the subcutaneous layer, and is more frequent in the facial area, with the main appearance of red color, which will not be higher than the surface of the skin, and its size will become bigger as the child grows up. 2. Capillary hemangioma: the most common type of hemangioma, it can occur in all parts of the body, mainly appearing as round or oval, slightly above the skin surface, bright red, and will become bigger as the children grow up. 3. Cavernous hemangioma: its lesion is mainly located in the subcutaneous or muscular layer, with soft appearance and easy to be compressed. The surface is greenish-purple, and when the cavernous hemangioma grows on the head and face, the tumor will be swollen due to blood congestion when bending down, and it will return to its original state after standing upright. 4. Mixed hemangioma: it refers to a kind of mixed capillary hemangioma and cavernous hemangioma, the surface features are similar to capillary hemangioma, and the internal lesions are the same as cavernous hemangioma. The four kinds of hemangiomas have different forms, and the treatment is not the same, so you should go to the regular hospital.
