Plexiform hemangioma

Introduction to plexiform hemangioma The plexus hemangioma (verrucoushemangioma), also known as angioblastoma, is usually 2 to 5 cm in size. The disease is common in infants and young children. It occurs in the upper part of the neck and trunk, and can be treated by pulsed laser or surgical resection. basic knowledge The proportion of illness: 0.12% Susceptible people: seen in babies and young children Mode of infection: non-infectious Complications: bloating, ascites

Cause of plexiform aneurysm

There are two kinds of vascular reticuloma: cystic and solid type, cyst type accounts for 60%-90%, parenchyma accounts for 10%-40%, derived from perivascular mesenchymal tissue, belongs to cell residual of mesodermal, capsule Containing yellow or yellow-brown liquid, high protein content, most of the cyst wall has a red tumor nodule, protruding into the cyst, under the microscope, the tumor is composed of blood vessels and cells, that is, blood-filled capillary network and blood vessels Reticulated endothelial cells.

Plexus hemangioma prevention

There are no effective preventive measures for this disease. Pay attention to health, do a good job of safety protection, reduce and avoid the irritating and accidental damage of adverse factors, can play a certain preventive role.

In addition, early detection, early diagnosis and early treatment are also the key to the prevention and treatment of this disease.

In case of onset, active treatment should be actively treated to prevent complications.

Plexus hemangioma complications Complications, abdominal distension, ascites

The complication of a hemangioma depends on its location, size and tissue composition. If the hemangioma grows on the face, it will inevitably affect the beauty. In severe cases, the facial features may be deformed; in the neck and throat, it may be easily broken due to eating, which may endanger the patient's life; in functional parts such as the eyeball, tongue, fingers, Toes, penis, clitoris and joints can affect the function of these parts.

When the tumor is enlarged, it can be pressed and moved into adjacent organs, and various symptoms appear. Such as compression of the lower end of the esophagus, stomach, duodenum, there will be dysphagia, abdominal distension, abdominal pain, belching and other symptoms; compression of the liver and biliary tract can cause gallbladder effusion, obstructive jaundice; compression portal vein caused by portal hypertension, inferior vena cava Pressurization can cause ascites, and pregnant women can affect childbirth. The swelling of the hemangioma due to internal pressure or external force (squeezing, impact, confrontational movement, etc.) hemangioma vascular rupture of the liver, causing death.

Symptoms of plexus hemangioma Common symptoms Papular diffuse vascular keratosis bloating and abdomen blood vessel wall and surrounding...

Dark red spots and plaques with unclear boundaries gradually increase, usually 2 to 5 cm in size, and some small hemangioma papules appear on some spots or plaques. This disease is common in infants and young children. Most of the upper part of the neck and trunk are progressively slow to increase, and they are benign, and even disappear naturally.

Examination of plexus hemangioma

Histopathology: small, limited capillary plexus and small lobes in the dermis, showing a shell-like appearance, a crescent-shaped fissure cavity around the capillary plexus, and a capillary glomerular appearance of the capillary plexus protruding into the fissure. The capillary plexus endothelial cells are dense, the lumen is not obvious, the endothelial cells of the larger vascular lumen, the VIII-factor-related antigen and the lycopene plant hemagglutinin immunoreactive.

Diagnosis and diagnosis of plexus hemangioma

diagnosis

It is reported that it can occur from newborn to 80 years old, but it is more likely to be young and young, 30 to 40 years old. Men are slightly more than women. About 6% of patients with retinal hemangioma are associated with cerebellar vascular reticuloma, and about 20% of cerebellar vascular reticuloma are associated with retinal hemangioma.

Differential diagnosis

Should be differentiated from vascular reticuloma, vascular reticuloma accounted for 1.5% to 2% of all brain tumors, accounting for 7% to 12% of posterior fossa tumors, occurring in the cerebellar hemisphere, Chinese data shows that Cerebellar hemispheres accounted for 62.3% to 80%, followed by cerebellar vermis or sinus in the fourth ventricle. The cerebellum accounted for 80% of the cerebellar vermis and 13% of the fourth ventricle. Tumors occupy only about 12% of the onset, which can be found in the frontal and temporal lobes, as well as in the brainstem, thalamus and spinal cord. The right side of the cerebellar hemisphere is more than the left side.
