Hemangioma can be divided into benign hemangioma, junctional hemangioma, malignant hemangioma and other types, and the performance of different types of hemangioma has some differences. The main manifestations are skin color change, morphology change, etc. 1. Benign hemangioma (see 1, 2, 6 as examples): (1) Infantile hemangioma: skin changes as bloody, abrasion-like or capillary dilatation patches are dominant, and the tumor body can proliferate rapidly in the first 6 months after birth, which is obviously higher than the skin surface. (2) Spindle cell hemangioendothelioma: it develops in the skin nodules of the limbs, accompanied by the production of vein stones. (3) Congenital hemangioma: it can exist at birth, mainly manifested as purplish-red elevation or plaque, with clear boundary, irregular shape, and discoloration when pressed. (4) Plexiform hemangioma: the size of the lesion is 2-5cm, common in infants and young children, preferably occurring in the upper part of the neck and trunk, as the dark red spots and papules with unclear boundary. (5) Epithelioid hemangioma: single or multiple red nodules gradually develop into red hard swelling, and even ulcerate and bleed. (6) Pyogenic granuloma: a kind of benign swelling of skin with rich blood vessels, mostly formed after trauma, with rapid growth and easy bleeding. (2) Junctional hemangioma: the performance is more diversified, it can appear purplish red nodules or plaques on the skin and mucous membrane, which can be accompanied by varicose veins on the surface of the skin, elevated temperature of the skin, purpura, petechiae, pain and other symptoms. 3. Malignant hemangioma: common metastatic sites include liver, lung, bone and brain metastasis, which cause dysfunction of metastatic organs, such as impaired liver function, dyspnea, dizziness and headache, or pain in bone metastatic sites. Once the above abnormalities occur, attention should be paid to consult the hospital in time.
