Pomocna the tumor is a tumor of benign nature, formed from pomocnych cells (arteriovenous anastomoses). It belongs to the group of tumors in blood vessels. The mortality of patients who have been diagnosed glamurnye tumors, on average, is six percent. The immediate cause of death becomes a local progression of this disease. Such tumors most often affect women. They are found mostly in middle age. Recently, however, this disease occurs in young.
As in the case with a number of other cancers, the exact causes of the formation of glamurnoe tumor is still there. There is controversial speculation that her appearance causes trauma. Sometimes fails to detect the influence of heredity. It should be noted that about eight percent of patients before the appearance of their glamurnoe tumors had malignant tumors in various organs.
This entity is considered benign, i.e., not observed his rebirth. But currently, this statement is not quite clear. There are reports on the transition of these tumors are malignant. If a person has a persistent noise in the ear and pulse something strange, you need to urgently see a doctor.
The Dermatologists and oncologists believe that such neoplasms appear from pomysov. Specifically – from the channel Sucez-Goyer, inside is covered with endothelium, around which glamurnye cells. Last able to shrink, swell and stretch. Thus, they affect the width of the microvascular lumen. Also glomus are rich innervation.

Arteriole Anastomoses-venous present in the body almost everywhere. That is why we can say that pomocna tumor can appear in any organ. Mainly it affects the phalanges of the fingers and also the region of the jugular fossa and middle ear. These growths can be:
Multiple nodes are observed mainly in children. This kind of tumor is sometimes found in the child's parents or other relatives. In this case, the tumor is able to appear on various parts of the body. From pathologies of single tumors, they are distinguished by a rare discovery on a nail phalanx. Also they are not characterized by intense pain.
Glamurnoe formation located a single, externally is a small round node from 0.1 to 0.6 centimeters in diameter. Glamurnoe the size of the tumor in all individual.Node is most often on the skin of the finger, mainly in the area of the nail bed. To touch the soft node, is formed in the inner epithelial layer of the finger that is deep enough. Hue its color can vary from red to deep purple. In the presence located in the internal organs of the tumor, its size may be more – up to fifteen centimeters. Symptoms glamurnoe tumors is quite diverse.
At the host location under the nail, it is a round patch of bluish or red, the size of which comes to 0.5 inches. When the location of the pathology on the phalanx, it makes itself felt paroxysmal pain. Unpleasant sensations can be too intense. It is worth considering that its gain is influenced by various stimuli.
Along with the pain of the fingers can appear such feelings:
Very common pomocna tumor of the middle ear.
The Majority of patients concerned about the appearance of a gradually growing, not causing pain, but the pulsating mass on the neck. In some cases, found a tangible deterioration of the function of the middle ear. In addition, it is possible the following symptoms: difficulty swallowing, hoarseness, a number of problems with the movement of the tongue. Often, in addition to the noise in the ear pulsating - such a feeling.
Diagnosis Begins with a rigorous examination of the therapist's medical history and a thorough inspection of the affected area. This means that you can establish the location and size of the tumor, assumes a hypothetical anomalies in the nerves, the tumor. Also in the diagnostic procedure includes examination of ears, as it can help to see the pathology behind the eardrum.
Effective in the diagnosis are MRI and CT. These methods allow to determine the size of the tumor and to distinguish any other entity.
Quite often the test results to angiography (ie, the science that studies the functioning of blood vessels of the neck) are used to determine the nature of the supply of blood to the tumors, as well as to establish ways of circulation to the brain. In the majority of cases of tumor biopsy may not be made before the beginning of the therapeutic course, because it can cause bleeding.
Unlike pomocnych tumors from each other is what the elements in them mainly — nerve, muscle and blood. Depending on this classification there are the following forms:
Neoplasms multiple character similar to cavernous angioma. They are much smaller epithelioid tissue.
The Disease often affects the jugular fossa and middle ear cavity. This is manifested by a reduction of labyrinthine function and deafness. First in the ear throbbing. Then the process includes the branches of the facial nerve. If there are signs of neuritis of the facial nerve, it acts as a confirmation of the long existence of the tumor and affecting the it sphere jugular fossa.In the field of middle ear tumors originate from pomocnych Taurus, located in the adventitia tissue on the bottom of the tympanic cavity jugular vein, and also along the nerve of the same name. they also come from Taurus, located along the length of the vagus nerve and the auricular branch related to it. Tumor node includes many capillary, arteriovenous anastomoses, and between them across globe cell. In the tympanic cavity of the middle ear globe cells are sent from the sphere of the dome of the jugular vein. Then the tumor grows, eventually filling the cavity. There is a gradual decrease in hearing. Tumor growth continues, the eardrum begins to speak, and subsequently collapses under the influence of the tumor.
The location of tumors in the bulb or in the Cape jugular vein, pain gets strong expression. Complaints of patients that pulsing in the ear. When carrying out survey in the early period, found no defect of the eardrum. However, it is possible to guess the plot with a strong pulsation in it.
Over time the tumor increases in size, bulging, together with the eardrum towards the outer ear from the middle. It is worth noting that it becomes very similar to a polyp. When viewed in the later stages, the middle ear is bleeding from the touch and has the appearance of a polyp. Also, the tumor can spread to areas of the inner ear, cranial cavity, cranial temporal bone.
You can Also find glamurnuyu tumor called paraganglioma. This is a slow-growing benign tumour in the brain originating from paraganglionic cells the internal jugular vein. She is of the vascular plexus with inclusions pomocnych cells. In their growth often involved the caudal cranial nerves and blood vessels. It consists of chromaffine cells, in some cases, it accompanies the active secretion of catecholamines.
In women is diagnosed six times more often than men. On average, the disease is detected in a 55 years and older. These neoplasms reveal extracranial or intracranial. Patients with reduced hearing, there is a ringing in the ears, paresis of the facial muscles, it is noted labile blood pressure. If the case is running, you can detect the signs of compression of the brain stem.
In most cases, surgical treatment. Glamurnye education have low sensitivity to radiation therapy. However, in some cases, it is recommended. Using electrocoagulation problems are not solved. After some time, a recurrence.
Although glamurnye brain tumors and some other organs are defined as benign, surgical intervention during their treatment is difficult, because they have a strong blood supply. Therefore, there is a risk of serious blood loss. So, if during the operation of the finger, the danger is not too high, in the inner ear and behind the wall it is higher because of nearby vital structures. Rather high risk of damage. This is especially true for large tumors, including...
