What is a hemangioma? What is a hemangioma?

Hemangiomas can be essentially divided into two types: one is vascular malformation caused by abnormal angiogenesis during embryonic development, overdevelopment or abnormal differentiation of blood vessels (hamartoma), and the other is a true tumor caused by abnormal proliferation of vascular endothelial cells.

Hemangioma refers to a benign tumor that occurs in vascular tissue, which is formed due to the misartery and neoplasia of vascular tissue. It is divided into two types: primary and secondary, of which primary accounts for 75 and secondary accounts for about 25. Secondary forms are mostly present in infancy, a few in adulthood,** and are not known.

Primary, i.e., congenital viviparity, is formed by the proliferation of the vascular network in the human embryonic stage, which is present at birth, and can be asymptomatic when the hemangioma is small. Hemangiomas can occur in various parts of the body, on the face and exposed parts of the limbs, and can affect the appearance. It compresses and destroys the function and morphology of surrounding tissues and organs to varying degrees, affecting the growth and development of the human body.

Some can bleed and become infected repeatedly, and a very small number of people will have malignant transformation, even life-threatening.

Traditional Chinese medicine believes that hemangiomas are caused by heat poisoning, irritation of the heart, and abnormal blood flow, so that the qi and blood are vertical and horizontal, the veins are intertwined, and the formation is condensed, which is exposed to the skin or internal organs. Treatment: cool blood and stasis, dispel fire and nourish yin.

Hemangioma should be early**, the earlier it is, the better the efficacy and prognosis.

Tumors that arise from vascular tissue are called hemangiomas, and 80% of them are congenital. Hemangiomas are benign, grow slowly, and rarely become malignant.

Capillary hemangioma: It is formed by superficial telangiectasia, tortuous, and circuitous. Hemangiomas are more common in babies at birth (about 1 3) or shortly after birth (within 1 month).

It originates from residual embryonic vascular blasts. Its histopathological characteristics are that the tumor is rich in proliferative vascular endothelial cells, and there are angioblasts and mast cell aggregation. Hemangiomas occurring in the oral and maxillofacial areas account for about 60% of systemic hemangiomas, most of which occur in the face, neck**, subcutaneous tissues, and very few in the oral mucosa.

Deep and intramaxillary hemangiomas are currently considered to be vascular malformations. Red spots or small red spots can be found at birth, which gradually grow, and the red color deepens and rises. Capillary hemangiomas often grow faster than infants.

The tumor has a clear boundary, and it can fade slightly when pressed, and return to red after relaxation. It can be frozen** or surgically removed, or x-rays**.

Cavernous hemangioma: Usually made up of small veins and fatty tissue. Its shape and texture resemble a sponge, so it is called a cavernous hemangioma.

Most of them grow in the subcutaneous tissue, but they can also be in the muscles, and a few can be in the bones or internal organs. Subcutaneous cavernous hemangioma may cause a slight local bulge,** normal,** or a bluish-purple color, and the lump is soft and clear. **Ansosectomy should be performed as soon as possible.

Small cavernous hemangiomas may also be injected locally with an angiosclerosis agent (eg, 5 sodium cod liver oleate).

There are many types of hemangiomas, and patients often confuse bright red nevi with hemangioma, bright red nevus is not prominent**, it is light red and pink, and the area will expand and deepen with age; Hemangiomas, on the other hand, protrude**, start as small red spots and grow rapidly after that.

Bright red nevus: also known as microvenous malformation or wine-like nevus, manifested as one or several dark red or red patches, with irregular edges, not high above the skin surface, easy to fade when pressed, the head and neck are more common, often appear at birth, and can increase as the human body grows.

Strawberry-shaped hemangioma: presents as one or more red, soft, lobulated tumors, which do not fade under pressure, tend to occur on the head and neck, usually do not appear at birth, but appear within a few weeks of birth, enlarge within a few months, grow rapidly, and even reach several centimeters.

Hemangiomas are congenital benign tumors or vascular malformations that are formed by the proliferation of angioblasts during the embryonic period, and are commonly found in the infants 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.

Hemangioma is a congenital benign tumor and a vascular malformation. Hemangiomas are caused by small areas of genetic misformation during embryonic development. It is more common in babies born or shortly after birth.

Hemangioma disease is mainly the remaining embryonic angioblasts, those more active endothelioid germ will invade adjacent tissues, forming an endothelial like cord, which is formed by connecting with the remaining blood vessels after tubulation. Most hemangiomas occur in infants and children, and hemangiomas are mostly on the surface, subcutaneous tissues, as well as oral mucosa, such as tongue, lips, mouth and other tissues, and a small number of hemangiomas are affected in the inner and deep tissues of the jaw.

Hemangioma is caused by the proliferation of the vascular network in the embryonic stage, which is a common disease in children and can grow in any part of the body, with ** and subcutaneous tissues being more common.

Tumors that occur in vascular tissue are called hemangiomas, which are benign, slow growing, and rarely malignant. This kind of tumor is mainly congenital, often manifested as local discomfort, or abnormal appearance, although it is a benign tumor, but it also needs to be detected early**, the main method is laser**, the effect is better, and the trauma is relatively small. If the site of hemangioma growth is not treated in time, it will often lead to damage to the organs in the area, and finally it can be life-threatening, so it needs to be treated as soon as possible.

Surgery can also be taken**, and the surgical site must be iced or cooled ** after surgery to keep ** moist. It is advisable to do so under the guidance of a medical professional.

Hemangiomas are tumors that occur from vascular tissue, and hemangiomas in the body are generally asymptomatic at the beginning, and when the tumor enlarges, it can compress and move to nearby organs, causing various symptoms. The use of surgery or high-frequency electrodes can be completely **, high-frequency electrodes are purely physical** methods, do not have any effect on growth and development, and **will not** later**. Hemangiomas will gradually grow, and the bigger they grow, the more difficult it will be.

Hemangioma is a change in the shape of a normal blood vessel, local enlargement and expansion, forming a change similar to a balloon, just like a bead on a line, hemangioma is benign, just a change in the shape of blood vessels, as long as the size is stable, there is no short-term enlargement or obvious discomfort, don't worry about it, it will not have any impact on people, rest assured, as long as it is checked regularly!

Hello, hemangioma bright red nevus, also known as flame nevus, telangiectasia nevus and wine nevus, strawberry hemangioma, also known as capillary hemangioma or simple hemangioma, cavernous hemangioma, mixed hemangioma. Hope mine is helpful to you.

Hemangioma will have certain genes, but there is no inevitable heritability, and now it is found that there is also a hemangioma on the umbilical cord, so it must be carefully considered.

Hemangioma is generally a benign tumor caused by local capillary hyperplasia and dilation, and is generally due to vascular dysplasia or vascular malformation caused by excessive development and differentiation of blood vessels. Hemangiomas mainly include the proliferation of blood vessels, lymphatic vessels, walls and their surrounding tissues. There are generally three types of factors that contribute to the formation of hemangiomas:

Genetic factors form hemangiomas.

Hemangioma is formed by traumatic factors.

Intrinsic hormonal factors form hemangiomas.

Hemangioma is a common benign tumor or vascular malformation, which is caused by vascular hyperplasia, commonly longer than soft tissues such as blood vessels and internal organs, and is also diverse, and there are many types of hemangioma, so in general, hemangioma is not dangerous, because the greatest possibility is the rupture of blood vessels leading to bleeding. If it is a capillary hemangioma or a disease that is not very serious, and there is no rupture and bleeding of the hemangioma in the important organs, it will not have a particularly big impact on the human body, and the positive ** can control the bleeding. If it is an abdominal aortic hemangioma or an aortic dissection hemangioma, once it ruptures and bleeds, hemorrhagic shock will occur in a short period of time, which can be life-threatening.

If the hemangioma occurs in the brain, rupture and hemorrhage will cause cerebral hemorrhage, affect the movement of the patient's limbs and even leave sequelae, and some patients will occur in the center of life, which will also endanger the patient's life. If a hemangioma is found to have a special site, it needs to be actively treated, including surgery, conservative, surgery, which is mainly divided into open surgery and interventional surgery, and it is necessary to decide which method according to the specific condition of the patient.

If you still have relevant questions, you can go to the official website for consultation.

Hemangioma is a very common disease and a relatively serious disease. Hemangiomas are mostly seen in infants and children, and usually grow in a more conspicuous area, which can seriously affect the child's appearance. Therefore, the development of hemangioma must be timely and allowed to develop for a long time, which will have a great impact on the child's psychology and affect the child's physical health and psychology.

More seriously, hemangiomas can bring many complications, and the impact of these complications should not be underestimated.

Tubular tumors refer to abnormal angiogenesis or vascular malformations, which can be roughly divided into three categories, including capillary hemangiomas, cavernous hemangiomas, and cranoid hemangiomas. The onset and mode of onset of the three classifications are different. Capillary hemangiomas mostly occur in infants and young children, and with the physical development of infants and young children, capillary hemangiomas can often regress on their own, so most capillary hemangiomas do not need **; Cavernous hemangiomas are the most common type of hemangiomas that can occur in limbs, muscles, and even internal organs.

If there is an indication for this type of hemangioma, surgery or intervention is required.

It is the excessive proliferation of blood vessels, the formation of tumor-like changes (better understood is a lump), and the risk is related to the location and size of the body, etc., and there are also differences.

It's very dangerous, I only know the fur, I don't dare to talk nonsense, you have to ask the doctor for details.

The pathogenesis and pathogenesis of hemangioma are still unclear, and it is mainly believed that it is closely related to "angiogenesis" and "abnormal proliferation of blood vessels", and in recent years, the latter is believed to play a major role.

The pathogenesis of hemangioma is not well understood, and its formation may be caused by a variety of reasons, such as the imbalance between angiogenesis and angiogenesis inhibitors, changes in the expression of extracellular matrix and proteases, and mutations in some pathogenic genes or inactivation of tumor suppressor genes, resulting in changes in the local microenvironment and abnormal transformation of endothelial cells, resulting in abnormal proliferation of vascular endothelial cells.

Predisposing factors for hemangiomas:

Studies have shown that long-term maternal exposure to harmful substances such as leather, plastics, paints and coatings, as well as daily exposure to chemical fertilizers and pesticides, are risk factors for infantile hemangioma.

The predisposing factors for hemangiomas in adults remain unclear.

The pathogenesis of hemangioma is not well understood, and its formation may be caused by a variety of reasons, such as the imbalance between angiogenesis and angiogenesis inhibitors, changes in the expression of extracellular matrix and proteases, and mutations in some pathogenic genes or inactivation of tumor suppressor genes, resulting in changes in the local microenvironment and abnormal transformation of endothelial cells, resulting in abnormal proliferation of vascular endothelial cells.

The formation of hemangiomas is mainly caused by the reticular hyperplasia of blood vessels in the embryonic stage, also known as vascular malformations. Its incidence is also associated with an increase in estrogen.

The occurrence of hemangioma is generally related to congenital dysplasia, which is a congenital disease of the vascular system. If a pregnant woman uses exogenous chorionic gonadotropin or progesterone and other drugs during pregnancy to protect the fetus**, the chance of having a child with a hemangioma is correspondingly higher.

In daily life, due to the living environment and work pressure, it often leads to the occurrence of hemangioma, and then I will explain to you what kind of disease hemangioma is.

1.First of all, hemangioma is a vascular disease that causes poor blood flow and often causes local tissue necrosis.

2.secondly, those who are not higher than ** are bright red or purplish-red, with a clear perimeter, irregular appearance, and wine spots; The surface of the higher ** is uneven, like bayberry. When the tumor is compressed, the surface color fades due to the blood flowing out of the tumor, and after the pressure is relieved, the blood immediately fills the tumor and returns to its original size and color.

3.Finally, the surgical method is to remove the diseased tissue to achieve the best purpose, which is good for independent and small lesions. In general, the lesion area is rich in blood vessels, the amount of blood is large, and the amount of bleeding during surgery is very large, which often causes severe hemorrhagic shock, and a large amount of whole blood needs to be transfused during the operation, which is difficult and dangerous.

At the same time, because the hemangioma is often forced to terminate the operation after hemorrhage, it is often impossible to completely remove it, so the postoperative rate is very high. Surgical resection of part of the tumor leaves local deformities, deletions, and dysfunction. Facial capillary hemangioma can be combined with cosmetic transplantation to repair the lesion.

Therefore, the indications should be strictly grasped and the value of surgery should be weighed before it can be determined whether to choose surgery**.

Precautions. After the occurrence of hemangioma, it often makes blood circulation poor, so do not eat some greasy food in daily life, greasy food will lead to high blood lipids, increase blood viscosity, and make blood circulation more difficult.
