Hemangioma is congenital benign tumor of blood vessels or vascular malformation, it is one of the common tumors of soft tissues, mostly occurring in infants and children, more than half of them occur in the head and neck. (I) Classification of hemangioma 1. According to the size, clinical and histological characteristics of hemangioma, it is divided into the following types (1) Neonatal spot: it is a kind of small area capillary plaque commonly seen in newborn babies between the eyebrows or occipital area. It often disappears after a few months and does not need treatment. (2) Spider nevus: It is a kind of capillary lesion shaped like a wheel, with a center and tiny capillaries radiating from it. It is most common on the face and is diverse. It does not disappear until the child is a few years old. (3) Capillary hemangioma: Capillary hemangioma is a tumor composed of endothelial cells. They occur mainly on the facial skin and are mostly found in infancy or after birth. They are generally divided into two types: one is dark red or purplish-red plaque, not protruding from the skin, with clear circumference, discoloration by pressure, and return to its original shape when pressure is removed, which is known as wine patch hemangioma; the other is papillary or polypoid, protruding from the skin, similar to prune-like, which is known as prune-like hemangioma. (4) Cavernous hemangioma: it occurs in cheek, tongue, neck, base of mouth, lip and other parts of head and neck, and it is common in infants, young children and children. When the location is superficial, the surface of the tumor is light blue or purple, and when the location is deep, the surface of the skin is normal in color and luster, with soft texture and unclear boundary, and the volume can be reduced by compression, and it will be restored to its original shape when it is removed. In some tumors, vein stones can be detected. The postural test is positive, and coagulated blood can be extracted by puncture. (5) Trapezoidal hemangioma: trapezoidal hemangioma is due to embryonic vascular malformation, not true tumor. It is commonly seen in young people, and it occurs in the region of the head and neck innervated by the superficial temporal artery. The skin color is normal, obvious blood vessels are seen to be tortuous in the form of rosary, obvious pulsation is detected, there is blowing-like vascular murmur on auscultation, and the local skin temperature is increased. (6) Central hemangioma of the jawbone: Central hemangioma of the jawbone is a benign tumor originating in the jawbone and characterized by vascular proliferation and dilatation. 2.According to the biological behavior of hemangiomas, they can be divided into: (1) True hemangiomas: Most of them appear about 1 month after birth, and there is a proliferative period lasting for about 3 months to a peak and then more stable, followed by a slow and almost complete degeneration. (2) Vascular malformations: usually appear at birth and grow with the child’s body. Vascular malformations can be a combination of capillaries, veins, arteries and lymphatic vessels. (II) Treatment 1. Hormonal treatment: It is suitable for cavernous or capillary hemangioma in infancy and childhood, with large lesions, which are difficult to be effectively treated by other methods. 2.Low-temperature freezing, laser and nuclide dressing treatment: mainly applied to superficial, subcutaneous and submucosal capillary hemangioma or cavernous hemangioma. 3.Sclerosing agent and paxillin intracavitary injection: applicable to cavernous hemangioma, mainly using sclerosing agent and paxillin injection, resulting in reactive hyperplasia of endothelium or formation of embolism, so as to make the lumen occluded and the hemangioma fibroblasted. 4.Surgery treatment: It is suitable for trapezoidal hemangioma, centralized hemangioma of jawbone, limited, and cavernous hemangioma which is ineffective to be treated by other methods, and the tumor is persistently enlarged, causing deformity, dysfunction, or serious bleeding.
