Hemangioma is a congenital benign tumor or vascular malformation formed by the proliferation of angioblasts during the embryonic period, which is common in ** and soft tissues, and is more common at birth or shortly after birth. The residual embryonic angioblasts, active endothelioid germ, invade adjacent tissues to form endothelial cords, which are connected to the remaining blood vessels after catheterization to form hemangiomas, and the intratumoral blood vessels are self-contained and not connected to the surrounding blood vessels. Hemangiomas can occur throughout the body, with oral and maxillofacial hemangiomas accounting for 60% of total hemangiomas, followed by the trunk (25%) and extremities (15%).
Most of them occur on the face**, subcutaneous tissues, oral mucosa, such as the tongue, lips, floor of the mouth, etc., and a few occur in the jaw or deep tissues. It is more common in women, and the male-to-female ratio is about 1:3 1 4

At present, the most common methods for hemangioma are drugs, lasers and surgery, and there is no one method that can be used for all types of hemangiomas. It depends on factors such as the type, location, depth and age of the tumor. Commonly used methods are:
Surgical resection, radiation**, cryosurgery, sclerotherapy injection, laser irradiation, etc.
The principles are: prevention or**serious life- or function-threatening related complications; Prevention of malformations or facial defects after hemangioma regression; Prevent ulcers and infections, promote ulcer healing, reduce scarring, and relieve pain in patients who have already developed ulcers; Alleviate the psychological stress of children and their families; Avoid overdoing ** lesions that resolve spontaneously and have a good prognosis.

Hello, hemangioma is not a tumor in the traditional sense, but a condition caused by the local expansion of blood vessels, but if it is serious, it belongs to the same nature as the tumor, so it is hoped that the diagnosed patient will go to the hospital in time**.

The mechanisms of hemangioma formation are diverse, and the specific causes of their pathogenesis are unknown. Congenital dysplasia, autometabolic disorders, infectious factors, chemical drugs, radiation, hormones, etc. can cause abnormal development and proliferation of blood vessels, vascular malformations caused by abnormal vascular morphology and lumen caused by certain genres, as well as trauma and drug factors can lead to the formation of hemangiomas.

A hemangioma is a red or purple lump that appears on or elsewhere in the body caused by abnormal growth of blood vessels.
Hemangiomas in infants grow rapidly after birth and grow rapidly in size for the first 6 to 18 months, after which they begin to shrink. About 3 in 4 cases of hemangiomas disappear by age 7 years, although residual hemangiomas may be slightly heterochromia and scarring. Hemangiomas can also develop in middle age and beyond, especially in the trunk.
Infantile hemangiomas: they grow intradermally or subcutaneously. They cause **bulging, purple in color, and flesh-colored if the location is darker.
Although some are located in deep hemangiomas that are larger, most are in between. About half of them occur in the head and neck. Sometimes hemangiomas occur in internal organs, such as the liver.
Infantile hemangiomas are **, but occasionally rupture and bleed. Hemangiomas around the eyes can block vision when enlarged to a certain extent, which can lead to permanent blindness if not controlled. Hemangiomas can also block the nasal passages and throat, causing breathing problems.
Because infantile hemangiomas usually resolve on their own, doctors generally do not give them when they first appear** unless they grow too quickly, block vision or breathing, form ulcers, or have a cosmetic appeal.
Oral or injectable corticosteroids or lasers may be given when needed**. Surgical excision is generally not recommended because most lesions resolve spontaneously and leave little scarring. In older children, surgery may be used when the hemangioma has shrunk to its maximum, which may be helpful in improving aesthetics.
Superficial hemangioma: very common, also known as cherry hemangioma or strawberry hemangioma. It usually appears as raised, red vascular growths on the trunk, ranging from several to dozens of them. Superficial hemangiomas are harmless and can be removed with an electric needle or scalpel.
How can hemangiomas be **?
Whether hemangioma can be **, most of them can**, some patients with benign hemangioma can regress on their own, but the time of regression cannot be determined. There are many methods for hemangiomas, such as drugs, lasers, and surgeries, which can make most patients achieve good results. Which method to use, it is best to determine the method after diagnosis by a doctor.

Before hemangioma, it is necessary to make statistics according to the individual's location and type, as well as the depth and age of the hemangioma, and then according to different physical conditions and conditions, surgery**, or radiation**, or cryosurgery**, etc., can be carried out by laser irradiation**. It is important to have a detailed physical examination before you can take different measures for different situations.
Some cavernous hemangiomas are venous malformations, and the malformed blood vessels and the surrounding normal tissues are not cleanly resected. >>>More
Capillary hemangioma is a type of hemangioma, which is more common and belongs to vascular malformations. It can be divided into neonatal nevus, port-wine spots, spider nevi, strawberry capillary hemangioma, familial hemorrhagic telangiectasia, granuloma hemangioma. The clinical manifestations are as follows: >>>More
Hello, laser ** will not affect the development of brain, intelligence, etc., the biggest disadvantage of laser is to leave a scar, if it is a general ordinary laser, it will be painful, if it is an infant or young child, parents will definitely feel distressed, in addition, if the laser is not in place, hemangioma has the possibility of **, if there is only a laser in the local area, you can measure the situation of hemangioma, for example, the area of hemangioma, type, etc., if the area is very small, you can use laser**, a little slight scar, When the child grows up, it is not very obvious, but if the area is relatively large, the scar is more obvious, it is necessary to consider carefully, in addition, it is necessary to confirm what type of hemangioma it is, the laser can only ** hemangioma (strawberry hemangioma) on the surface of the skin, if it is a mixed or cavernous hemangioma, do not consider using a laser, because it can't**. In addition, if there are nuclides in the local area, you can consider using nuclides**, which are not painful, do not leave scars, and can easily ** strawberry hemangioma.
Hemangioma is formed by the continuous proliferation and telangiectasia of capillary endothelial cells due to the impaired development of blood vessels in the embryonic stage. Vascular malformations are formed due to congenital malformations of vascular development, resulting in flexion and dilation of local veins and lymphatic vessels. >>>More
