What type of disease is hemangioma?

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.

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.

There are many types of hemangioma diseases, and each type of hemangioma has its own different symptoms. Hemangiomas are tumors that develop in vascular tissue, 80% of which are congenital. Hemangiomas are benign, grow slowly, and rarely become malignant.

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.

The harm of hemangioma depends on the location, size and tissue composition of the hemangioma. If the hemangioma grows on the face, it will inevitably affect the cosmetology, and in severe cases, it can make the facial features deformed; In the neck and throat, it is easy to cause ulceration due to eating, which can endanger the patient's life; Functional areas such as the eyeball, tongue, fingers, toes, and joints can affect the function of these areas. If the hemangioma is huge, no matter where it grows, it will seriously endanger the patient's health, and in addition, the hemangioma can also cause infection, ulceration, bleeding and even malignant transformation, which will seriously endanger the patient's life, so it is necessary to have a hemangioma.

Hemangioma, also known as infantile hemangioma (IH), is the most common benign tumor in infants and young children, which is a true vascular tumor caused by the excessive proliferation of normal vascular tissue in the mesoderm. Hemangiomas tend to occur in the head, face, and neck, followed by the limbs and trunk. Occurs in about 30% of neonates at birth and usually grows slowly at 2 or 4 weeks of age, resulting in 10% to 12% at 1 year of age.

Female infants are more common than male infants, with a ratio of 2 5:1, and the proportion of multiple babies is 15% to 30%.

1. Hemangioma is a congenital benign tumor or vascular malformation, which is more common in babies born or shortly after birth, occurring in the oral cavity, maxillofacial hemangiomas account for 60% of systemic hemangiomas, most of which occur in the face**, subcutaneous tissues and oral mucosa, such as tongue, lips, floor of the mouth and other tissues, and a few occur in the jaw or deep tissues.

2. Intelligent intracavity ** system.

According to the modern classification system, hemangiomas are divided into the following types:

1: Infantile hemangioma. It is the most common benign tumor in infants and has three stages of development:

8 12 months of rapid growth, 1 12 years of longer degeneration and varying degrees of fiber fat residue at the end of the phase. Bright red and bright red are superficial, and blue or colorless under the skin. There is a chance of natural regression.

2: Capillary malformation. These include the common bright red nevus (port-wine stain), which is not characteristic of vasodilation in childhood, and the number of diseased blood vessels may increase with age, and it can also form nodular, sometimes involving deeper tissues, and occasionally thrombosis.

3: Venous malformation. It is formed by the abnormal enlargement and dilation of local venous vessels.

4: Lymphatic malformation. Traditionally called lymphangiomas, they are more common in children and adolescents. It can occur in the epidermis, dermis, or extend to deep soft tissues.

5: Arteriovenous malformation. It is present at birth and rarely occurs during puberty. Due to the continuous enlargement of the incoming and outgoing blood vessels and the formation of collateral branches of the blood vessels, the child grows and grows up.

Hello, hemangiomas are divided into seven categories: infantile hemangiomas; Congenital hemangiomas (rapidly regressing and non-regressing and partially regressing); plexiform hemangioma; Kaposi-type hemangioendothelioma; spindle cell hemangioendothelioma; Other rare hemangioendotheliomas; Keratinizing hemangioma.

Capillary hemangioma is a very common hemangioma disease due to congenital developmental abnormalities due to the expansion and hyperplasia of the vascular network during the embryonic period.

It is harmful to health, so it is important to ** capillary hemangioma in time. There are many types of capillary hemangiomas, and the methods are different. It can be divided into strawberry-like capillary tumors, neonatal nevus, bright red nevus, port-wine stains, and hemorrhagic telangiectasia.

There are different types of hemangiomas, mainly capillary hemangioma, strawberry hemangioma, cavernous hemangioma and mixed hemangioma.

Strawberry hemangioma.

Cavernous hemangioma.

Mixed hemangioma.

Lymphatic hemangioma.

Cranoid hemangioma.

Capillary hemangioma.

Bright red spots. Hepatic hemangioma.

Vasculature malformations.

According to the type of diseased blood vessels, hemangiomas are divided into capillary hemangiomas, cavernous hemangiomas, and cranoid hemangiomas.

1.Capillary hemangioma: red spots or small erythema at birth or early postnatal time, which gradually increase, deepen the redness, and may be raised.

2.Cavernous hemangioma: Usually made up of small veins and fatty tissue. Most of them grow in the subcutaneous tissue, but they can also be in the muscles, and a few in the bones or internal organs.

3.Cranoid hemangioma: consists of thicker relocated blood vessels, mostly venous, but also arteriovenous fistulas. In addition to subcutaneous and muscular occurrences, it often invades bone tissue, which can be larger, even more than one limb.

1Berry hemangioma (also known as infantile hemangioma, capillary hemangioma): It is formed by superficial telangiectasia, tortuous, and tortuous, and the tumor body is often higher than the ** surface.

2 Cavernous hemangioma (also known as venous malformation): It is generally composed of small veins and fatty tissue. The shape and texture are sponge-like, so it is called 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.

3 Mixed hemangioma (mixed hemangioma in 2, often mixed strawberry hemangioma and cavernous hemangioma): at the beginning, most of them are small red spots of different surface sizes, and with the development of surface hemangioma, the appearance is red and blue, and it invades the dermis and subcutaneous tissue at the same time, and the scope of subcutaneous invasion can exceed the surface lesion area, forming a raised mass with irregular shape, mostly seen in the face and limbs.

4. Bright red nevus (also known as port-wine nevus or microvenous malformation): often appear at birth or shortly after birth, more likely to occur on the face, neck and scalp, mostly unilateral, occasionally bilateral, sometimes involving mucosa, often not higher than the surface.

5 Cranoid hemangiomas (also known as arterial malformations): composed of arteries or part of veins, palpable pulsatility, and high local skin temperature. Clinically rare.

There are five types of hemangiomas that are common in children:

Orange spots are present after birth, the size of the plaques varies, orange-red or light red, not higher than the ** surface, fade when lightly pressed, and the color darkens when crying. Orange spots are more common on the forehead, upper eyelids, and occipital area and usually resolve spontaneously within a few months of life and do not need to be treated.

Erythema nevus is also known as port-wine stain. Immediately after birth, it is a pale red or dark red plaque, which does not fade when pressed, does not rise above the ** surface, is located in the dermis, and is composed of a capillary network. After birth, the erythematous nevus grows proportionally with the growth of the body, but the extent no longer expands.

Erythema does not go away on its own. In addition to affecting the appearance, erythematous nevi generally have no other harm, and can be frozen if necessary**.

Capillary hemangiomas are more common in **, with the occipital, head, face, limbs and back being the most, and many longer than the lips and tongue. Capillary hemangiomas vary in size, from large ones that can occupy most of the face or limbs, to small ones that are only a few millimeters and slightly higher than **. Capillary hemangiomas are generally present after birth, grow rapidly within 6 months, and gradually stop growing after 1 or 2 years of age.

It is aesthetically pleasing and poses a risk of massive bleeding after breakage, so parents should pay close attention to it. If the hemangioma is small, slower-growing, and not in the exposed area, it can resolve on its own when it stops growing. If the hemangioma grows rapidly and seriously affects the aesthetics, it should be carried out immediately**, and isotope dressing and other methods can be used**.

Cavernous hemangiomas can occur in **, subcutaneous tissues, muscles, and even liver, kidneys, etc. The appearance is purple-red, surrounded by tortuous and distended small veins, which are soft and elastic, shrink when squeezed, and recover after decompression. This type of hemangioma grows in size as the baby gets older, sometimes very large and deep, severely damaging the appearance and destroying normal tissue.

Once the diagnosis is confirmed, it should be performed immediately**, with sclerotherapy injection or surgical excision.

Cranoid hemangiomas are more common in the limbs, with many dendritic dilated blood vessels on the surface and around them, tortuous and vine-like, locally** dark red or blue-purple, and sometimes the pulse of the blood vessels can be felt or the bruit of the blood vessels can be heard. For this type of hemangioma, surgery should be performed as soon as possible, and the limb can also be bandaged with elastic bandages to relieve symptoms such as soreness in the limb.

Hemangioma is a common benign tumor, which can be divided into congenital and acquired hemangiomas, and hemangiomas should be classified according to the location, depth and age of hemangioma. Hemangiomas mainly include capillary hemangiomas, cavernous hemangiomas, and cranoid hemangiomas, and the causes of the disease are not yet clear, and may be related to genetics, congenital dysplasia in the embryonic period, hormones, drugs, trauma, and environmental factors, and are usually caused by changes in the local microenvironment in the blood vessels and abnormal transformation of endothelial cells. It can occur on the face, limbs and other parts**, and can also appear in organs such as the liver.

If it is a small intracutaneous capillary hemangioma, neonatal capillary hemangioma, intrahepatic hemangioma, etc., and the growth is slow, there are generally no symptoms and will not affect the human body, and may even disappear with age, so it usually does not need to be special**. However, if the hemangioma affects the patient's face or life, grows too fast, is too large, etc., it needs to be considered on a case-by-case basis**.

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.

According to the common symptoms of hemangioma in life, it can be divided into the following types.

1. Bright red nevus: the color is red, dark red or purple-red, mostly occurring in the dermis layer under the epidermis, and there will be partial fading or complete fading when pressed, which is not higher than the normal surface.

2. Strawberry-like hemangioma: named because of its punctate appearance similar to strawberries, the color is mostly bright red or purple, soft to the touch, and the tumor will be higher than the surface.

3. Capillary hemangioma: generally present at birth, which is composed of dense and small capillaries formed by the proliferation of vascular endothelial cells. In the initial stage, it is in the shape of a sheet or vascular nevus, and the color is red, dark red or purple-red, flush with the surface of ** or slightly raised in**, soft to the touch, and faded by pressing.

4. Cranoid hemangioma: the color is mostly dark red or blue-purple, the blood vessels are tortuous and earthworm-curved or radially dilated like spider webs, the lesion is raised, auscultation or touching it with hands, you can feel the fluctuation of blood vessels or hear murmurs, and the soft boundary of the lump is not clear. Some cranial hemangiomas are painful because they become entangled with the nerves under the skin.

5. Cavernous hemangioma: the degree of damage of cavernous hemangioma is relatively large, the lesion mostly occurs in the deep dermis or subcutaneous tissue, the disease is more common in the head, jaw and face, and the bulge is normal**, which is blue or purple-red, and can be reduced by pressure, and it can be restored to its original state after decompression, and it can be basically diagnosed as cavernous hemangioma.

6. Mixed hemangioma: Mixed hemangioma has two or more types of hemangiomas at the same time, which are red plaques in the initial stage and continue to grow, and cannot invade deep tissues to form small mounds or nodular bulging masses, which are soft in nature, with unclear boundaries and reduced pressure.
