Glomus tumors are classified into types depending on where they begin to grow. They are typically benign and are treated by surgical removal. Glomus tumors affect females more often than males, and most patients are in their 40’s or 50’s at the time of presentation to the doctor. The carotid body is a small cluster of chemoreceptor cells, and supporting sustentacular cells.The carotid body is located in the adventitia, in the bifurcation (fork) of the common carotid artery, which runs along both sides of the neck.. The carotid body detects changes in the composition of arterial blood flowing through it, mainly the partial pressure of arterial oxygen, but also of carbon.

Surgery for glomus jugulare tumors may take many hours and a hospital stay of 3-4 days is generally expected.The modern surgical techniques have reduced the risk of postoperative stroke in carotid body paraganglioma resection to less than 5% [37,40,56]. However, the incidence of cranial nerve injury remains strikingly high, ranging from 20% to 40% [37,38,48,56,57]. In 20% of patients the neurological deficits is permanent. We found two (18%) transient hypoglossal, and one transient vagus nerve damage. recurrence after complete resection occurs in approximately 6% of patients [15,37,39,40,42,43,51,52]. In our study however, there were no recurrences. The patients with internal carotid artery reconstruction should undergo duplex scanning periodically to identify graft stenosis.Growth of these tumors is in a number of directions, typically extending into the mastoid air-cells, middle ear, and Eustachian tube. Removing tumors which grow in the internal jugular vein and extend into the base of the skull involves opening the vein with significant blood loss during tumor removal. Blood transfusion is often necessary. With several months planning, a patient may donate several units of his/her own blood for retransfusion during surgery.

Indium-111 labeled octreotide accumulates in these tumors due to the presence of receptors for somatostatin, best visualized with SPECT, but requires the tumor to be greater than 1.5 cm in diameter.If the tumor extends from the ear down into the internal jugular vein in the jugular foramen, preparations must be made for a larger type of surgical procedure to remove the tumor completely. Tumors in this location are referred to as glomus jugulare and tend to be larger at the time of diagnosis than other types of glomus tumors. This is because they do not cause a noticeable lump, problems with nerves, or ear blockage and pulsations until they are large. These tumors may have extensive invasion into the bony spaces in the base of the skull, as well as into the upper neck and into the intracranial space. The nerves exiting the skull through the jugular foramen are often adherent to the outer surface of this very vascular tumor. These nerves control the sensation and muscles of the tongue, the throat, the vocal cords, and the shoulder, and are at risk for injury during surgery. State of the art intraoperative nerve monitoring techniques are utilized to minimize nerve trauma during tumor removal.

Accordingly, paragangliomas are categorised as originating from a neural cell line in the World Health Organization classification of neuroendocrine tumors. In the categorization proposed by Wick, paragangliomas belong to group II.[10] Given the fact that they originate from cells of the orthosympathetic system, paragangliomas are closely related to pheochromocytomas, which however are chromaffin-positive.

Paraganglióm alebo tumor glomus caroticum je vzácny neuroendokrinný nádor, ktorý vyrastá z paraganglionického tkaniva, nachádzajúceho sa pozdĺž chrbtice od bázy lebky až po panvové dno. Viac ako 80% týchto nádorov vyrastá z drene nadobličky. 2 až 4% sa nachádzajú v oblasti krku, kde je najčastejším miestom glomus caroticum. Najvyšší výskyt je vo vekovej kategórii 50-60 rokov. Je 4-krát častejší u žien. A glomus tumor (also known as a solitary glomus tumor, solid glomus tumor,) is a rare neoplasm arising from the glomus body and mainly found under the nail, on the fingertip or in the foot.: 670 They account for less than 2% of all soft tissue tumors. The majority of glomus tumors are benign, but they can also show malignant features. Glomus tumors were first described by Hoyer in 1877. Surgery is the treatment of choice and if complete resection is achieved a cure can be expected. Complications are however not uncommon due to a large number of sensitive structures in the region and include: Glomus-Tympanicum-Tumor. 65-jähriger Patient.

Glomus jugulare tumors are defined according to the location (i.e. origin at the jugular foramen) rather than the anatomic origin and may arise from Jacobson nerve, Arnold nerve, or the jugular bulb 3.Paragangliomas originate from paraganglia in chromaffin-negative glomus cells derived from the embryonic neural crest, functioning as part of the sympathetic nervous system (a branch of the autonomic nervous system). These cells normally act as special chemoreceptors located along blood vessels, particularly in the carotid bodies (at the bifurcation of the common carotid artery in the neck) and in aortic bodies (near the aortic arch). Despite careful nerve monitoring, approximately half of patients who have tumors in the jugular foramen completely removed will have nerve deficits after surgery which did not exist before surgery. These deficits can result in difficulty swallowing, weakness of the voice, and weak cough. These problems are severe enough that subtotal tumor removal is often recommended. A small area of residual tumor can be left on the nerves and treated with focused radiation.The average age of the patients was 52 years (range 30–78 years). Eight of these cases presented as a large asymptomatic non-tender neck mass, and two each presented with dysphagia, and hoarseness of voice. As per Shamblin classification seven of tumors were type II and 5 were types III. In 7 cases subadventitial tumor excision was performed, while in 5 associated resection of both external and internal carotid arteries was carried out. The artery was repaired by end-to-end anastomosis in one case, with Dacron graft in one case, and with saphenous vein graft in 3 cases. There was no operative mortality. After a mean follow-up of 6.2 years (range 6 months to 20 years), there were no signs of tumor recurrence in any of the cases.Radiation therapy has been performed as a treatment for glomus jugulare tumors because surgery is long and can frequently result in numerous cranial nerve injuries. Although tumor growth can be stopped by radiation, symptoms such as pulsing in the ear are usually not. If surgery becomes necessary because of growth after radiation, surgery can be very difficult because of scarring caused by the radiation therapy and the ability to preserve nerves is diminished. In my practice, radiation therapy has been reserved to control tumor growth in elderly individuals or in those so medically compromised that they cannot tolerate surgery for tumor removal. In some cases where surgery is performed, a small area of tumor will be left over nerves and treated with focused radiation to preserve nerve function.

Surgical excision is the treatment of choice for carotid body paragangliomas although radiation therapy is an option for patients who are not ideal candidates for surgery. For the tumors that are in intimate contact with carotid arteries, the treatment by vascular surgeon is recommended. Paragangliom. Paragangliom nebo tumor glomus caroticum je vzácný neuroendokrinní nádor, který vyrůstá z paraganglionické tkáně, nacházející se podél páteře od báze lebky až po pánevní dno. Nový!!: Feochromocytom a Paragangliom · Vidět víc » Po On microscopic inspection, the tumor cells are readily recognized. Individual tumor cells are polygonal to oval and are arranged in distinctive cell balls, called Zellballen.[7] These cell balls are separated by fibrovascular stroma and surrounded by sustentacular cells. Intraoperatively on exploration of the neck seven of the cases showed a medium size tumor intimately associated and compressing carotid vessels (Shamblin II), and a large tumor involving carotid vessels in five cases (Shamblin III). In 7 cases of Shamblin II carotid body paraganglioma a subadventitial tumor excision was performed while in other 5 cases both external and internal carotid arteries were resected. One of these was repaired by end-to-end anastomosis, one with interposition of Dacron® graft, and other 3 were repaired with reversed saphenous vein graft. Das Paragangliom oder Chemodektrom ist ein Tumor und entwickelt sich aus einem autonomen Nervenknoten des vegetativen Nervensystems, den die Medizin auch als Paraganglion kennt. Die Neubildung kann sowohl gutartig als auch bösartig sein kann; mehrheitlich handelt es sich jedoch um einen gutartigen Tumor. Paragangliome lassen sich in verschiedene Typen einteilen: Das Paraganglioma tympanicum.

Glomus Tumors (Paraganglioma) Glomus tumor are typically benign but highly vascular tumors which arise in association with nerves which exit a very difficult anatomic area beneath the ear. Associated with tiny nerves which exit the skull adjacent to the carotid artery and internal jugular vein are tiny groups of cells called paraganglia Surgery for a glomus vagale tumor is generally done through an incision high in the neck. A secondary procedure to rehabilitate the paralyzed vocal cord is often necessary. Paragangliom des Glomus jugulotympanicum (1 p.)

This type of tumor is a non-cancerous, or benign, vascular tumor and it is also called a glomangioma or rare benign neoplasm which is an abnormal tumor or growth that consists of cells that divide and then reproduce independently of the normal tissue that surrounds it. It was first described in 1877 by a person named Hoyer but it was not until 1924 that a person by the.

Surgical complications and treatment outcome were noted and survival was calculated by actuarial method. The literature on carotid body paraganglioma was reviewed.Glomus tumor are typically benign but highly vascular tumors which arise in association with nerves which exit a very difficult anatomic area beneath the ear. Associated with tiny nerves which exit the skull adjacent to the carotid artery and internal jugular vein are tiny groups of cells called paraganglia. These cells have a special function of sensing gases in the bloodstream at the carotid bifurcation in the neck. These cells descend to the carotid artery along nerve branches as we are formed. Some of these cells can be left behind on the nerve which courses through the middle ear behind the eardrum and others may remain at the base of the skull in the jugular foramen, which is the name of the exit of the internal jugular vein from the skull. Most paraganglia ride along branches of the nerves down through the neck to the bifurcation of the carotid artery. If these nests of paraganglia begin to replicate abnormally, a glomus tumor results. A glomus tumor may also be called a paraganglioma. LF//Fingerlandův ústav patologie.

  3. The carotid body was first described by von Haller in 1743 [14]. It is highly specialized organ located at the common carotid artery bifurcation. Its feeding vessels run primarily from the external carotid artery. The function of the carotid body is related to autonomic control of the respiratory and cardiovascular systems, as well as blood temperature [3,10,12,15-23]. Paraganglioma is a relatively rare neoplasm occurring in carotid body [1-6].

Most paragangliomas are either asymptomatic or present as a painless mass. While all contain neurosecretory granules, only in 1–3% of cases is secretion of hormones such as catecholamines abundant enough to be clinically significant; in that case manifestations often resemble those of pheochromocytomas (intra-medullary paraganglioma).

If you have a medium and large glomus tumor, you will be asked to submit blood and urine tests to detect hormones which can be produced in up to 3% of tumors. It is important to detect these hormones before surgical removal because the hormones can spill from the tumor during surgical removal and cause the blood pressure to rise to dangerous levels. If you are determined to have a tumor which produces these hormones, you will be given medications to protect you from the effects of spilled hormones during surgery. Carotid body tumors (CBTs) are classified into sporadic, familial, and hyperplastic forms. The familial paraganglioma form is a genetically heterogenous entity; currently, 4 genes are identified. The first 3 genes encode the subunits of the enzyme succinate dehydrogenase complex, which is part of the Kreb's cycle..

  3. If the studies confirm that your tumor is very small and limited to the space behind the eardrum, the tumor is classified as a glomus tympanicum. These tumors are easily removed by lifting the eardrum through the ear canal or by making an incision behind the ear. In some of these tumors some removal of bone around the ear and mastoid is required to provide exposure for safe removal. This type of tumor is called a glomus hypotympanicum. Surgery for glomus tympanicum and hypotympanicum tumors can generally be done safely as an outpatient.
  4. Glomus tumors are uncommon, accounting for only 0.03% of all neoplasms and 0.6% of head and neck tumors. (15) The glomus tympanicum, however, is the most common tumor of the middle ear.

By light microscopy, the differential diagnosis includes related neuroendocrine tumors, such as carcinoid tumor, neuroendocrine carcinoma, and medullary carcinoma of the thyroid. About 75% of paragangliomas are sporadic; the remaining 25% are hereditary (and have an increased likelihood of being multiple and of developing at an earlier age). Mutations of the genes for the succinate dehydrogenase, SDHD (previously known as PGL1), SDHA, SDHC (previously PGL3) and SDHB have been identified as causing familial head and neck paragangliomas. Mutations of SDHB play an important role in familial adrenal pheochromocytoma and extra-adrenal paraganglioma (of abdomen and thorax), although there is considerable overlap in the types of tumors associated with SDHB and SDHD gene mutations. Paragangliomas may also occur in MEN type 2A and 2B. Other genes related to familial paraganglioma are SDHAF2[3], VHL, NF1, TMEM127[4], MAX[5] and SLC25A11.[6] Glomus caroticum-Tumore können jedoch auch sonographisch gut kontrolliert werden.

glomus caroticum - nádor - příznaky a léčb

Temporary facial weakness is the most common side effect in the removal of these tumors because the facial nerve often has to be moved out of its normal position to allow direct access to the jugular foramen. This is especially true in cases in which the tumor is also eroding the bone around the carotid artery.Tumors may be bilateral, and other tumors such as carotid body tumors may coexist. Up to 10% of the patients may have multiple lesions. Tumors are locally infiltrating, and may rarely metastasize 4.Wegen der möglichen Malignität der Paragangliome werden sie in der Regel gefäßchirurgisch entfernt. Manche Autoren empfehlen dabei eine präoperative Embolisation des Tumors. Aufgrund der engen Lagebeziehung zur Arteria carotis ist bei der Entfernung größerer Tumoren das Einsetzen eines Gefäßinterponats erforderlich. 1 Definition.

With immunohistochemistry, the chief cells located in the cell balls are positive for chromogranin, synaptophysin, neuron specific enolase, serotonin, neurofilament and Neural cell adhesion molecule; they are S-100 protein negative. The sustentacular cells are S-100 positive and focally positive for glial fibrillary acidic protein. By histochemistry, the paraganglioma cells are argyrophilic, periodic acid Schiff negative, mucicarmine negative, and argentaffin negative. A paraganglioma is a rare neuroendocrine neoplasm that may develop at various body sites (including the head, neck, thorax and abdomen). They are rare tumors, with an overall estimated incidence of 1/300 000. Unlike other types of cancer, there is no test that determines benign from malignant tumors; long-term followup is therefore recommended for all individuals with paraganglioma Gosepath J, Welkoborsky HJ, Mann W.

DOI: 10.1055/s-2007-997003 13 For a general discussion on the pathology of these tumors please refer to the generic article pertaining to paragangliomas.Planning for surgical excision of a glomus tumor may be straightforward or complicated. Usually, you will be asked to have a CT scan of the base of the skull to carefully define the size and shape of the tumor. An MRI and MRA exam is also very useful. Standard hearing testing can help determine if the inner ear is directly involved. A careful neurologic exam will be performed of the nerves involving the head and neck.

Carotid Body Tumors: Practice Essentials, History of the

Glomus tumor are typically benign but highly vascular tumors which arise in association with nerves which exit a very difficult anatomic area beneath the ear. Associated with tiny nerves which exit the skull adjacent to the carotid artery and internal jugular vein are tiny groups of cells called paraganglia. These cells have a special function [ Glomus caroticum-paragangliom. Behandlas i första hand med operation. Mindre tumör och yngre patient ökar indikationen. Man kan överväga strålbehandling i stället om tumören är stor eller om patienten är äldre med annan samsjuklighet. Jugulotympaniska paragangliom (temporalben). Eventuell operation av mindre tumörer het glomus caroticum gelegen in de vork van de grote halsslagader (arteria carotis) het glomus vagale gelegen nabij de 10de hersenzenuw; het glomus jugulare; het glomus tympanicum; Beide laatste ontstaan in het oor achter het trommelvlies. Vaak is de precieze locatie van oorsprong niet meer te bepalen en dan heeft men het over het glomus. The carotid angiography is the most useful diagnostic test for paragangliomas. The angiography demonstrates tumor blood supply and widening of the carotid bifurcation by a well-defined tumor blush ("lyre sign"), which is classic pathognomonic angiographic finding [5,8,37-39,42,43]. MR and contrast CT are more effective non-invasive imagining modalities comparing with duplex ultrasonography, especially for small tumors [3,37-39,42-45]. Radioimmunodetection of carotid body paraganglioma by 111In labeled anti-CEA antibody is also described in literature [9,46]. The differential diagnosis includes other tumors in this area, carotid artery aneurysms and elongation. For this reason using of precutaneous fine-needle aspiration for preoperative diagnosis of carotid body paraganglioma, can be very dangerous [47].

For a full list of differentials see the article on jugular fossa masses. General imaging differential considerations include: Paragangliomas of the head and neck originate most commonly from the paraganglia within the carotid body, vagal nerve, middle ear, and jugular foramen. Also called glomus tumors, they arise from paraganglion cells of neuroectodermal origin frequently located near nerves and vessels. Th Das Glomus-caroticum-Paragangliom ist ein seltener - meist benigner - Tumor im Bereich der Karotisbifurkation (Glomus caroticum). Er gehört zu den Paragangliomen. Frauen sind häufiger betroffen als Männer (3:1). Die klinische Untersuchung sowie die apparative Bildgebung können die Diagnose sichern. Bei der Palpation lässt sich das Paragangliom unterhalb des Kieferwinkels als lateral, aber nicht vertikal verschieblicher Knoten tasten. Richtungsweisend ist die MRT, die durch eine Duplexsonografie oder ein CT ergänzt werden kann.

Glomus caroticum er en ansamling av vegetative nerveceller i delingsstedet mellom de store halsarteriene arteria carotis interna og arteria carotis externa, i høyde med nedre kant av underkjeven.

They are highly vascular tumors and may have a deep red color. Genetic predisposition of familial glomus depends on one allele. The mostfrequent familial type of chemodectoma is the glomus caroticum tumour (up to 80%). A typicalmanifestation of paragangliomas is slow progression of growth. The first clinical signs of theseneoplasias are usually observed several years after development of the tumour

1. Introduction. Head and neck paragangliomas (HNPs) represent rare tumors of neural crest origin [], [].They are highly vascular neoplasms that are benign in the majority of cases [], [], [].They may occur along the paraganglia's pathway of embryologic migration extending from the skull base to the pelvic floor [], [], [], [], [].Paraganglia play an importatnt role in organismic homeostasis. Glomus caroticum-Tumore sind seltene, von nicht-chromaffinen Paraganglien der Halsregion ausgehende Neoplasien des Glomus caroticum, die von den an Kopf und Hals auftretenden Paragangliome mit ca. 60-70 % [Davidovic 2005] den Hauptanteil ausmachen. In der Gruppe der Paragangliome werden sie normalerweise zu de Das Glomus caroticum (von lateinisch glomus Knäuel und griechisch kara Kopf) ist ein kleines, knötchenförmiges Paraganglion, beim Menschen etwa 3 mm im Durchmesser, an der Aufzweigung der Arteria carotis communis (Halsschlagader) in die Arteria carotis interna und Arteria carotis externa im Halsbereich. Es besteht aus so genannten Hüllzellen und Hauptzellen, ferner. Als Glomus tympanicum und Glomus jugulare kommen vergleichbare Tumoren auch im Mittelohr vor (siehe Kapitel A).Patienten beiderlei Geschlechts im mittleren bis höheren Lebensalter sind betroffen. Ätiologie und Pathogenese Glomustumoren des Halses gehen von arteriovenösen Anastomosen im Bereich des Glomus caroticum aus Presentation depends on the degree of middle ear involvement. When significant involvement is present then the lesion may cause pulsatile tinnitus and hearing loss.

Glomus jugulare paraganglioma is a paraganglioma of the head and neck that is confined to the jugular fossa. While it is a rare tumor, it is the most common of the jugular fossa tumors.The carotid body paraganglioma (chemodectoma) is a relatively rare neoplasm of obscure origin. These are usually benign and commonly present as asymptomatic cervical mass. Paraganglioma oireet. A paraganglioma is a rare tumor that begins in certain nerve cells that are dispersed throughout the Surgery to remove the tumor is usually the first treatment choice for a paraganglioma, if feasible Paraganglioma Complications.These are non-cancerous tumors associated with Pheochromocytoma

If the tumor occurs at the level of the bifurcation of the carotid artery, it is called a carotid body tumor. These are typically noticed first as a soft lump in the neck. Surgery for a carotid body tumor is done through an incision in the neck, and rarely causes any nerve problems.Carotid body paraganglioma often present as slow growing, non-tender neck masses located just anterior to the sternocleidomastoid muscle at the level of the hyoid. The tumor is mobile in the lateral plane but its mobility is limited in the cephalocaudal direction [3-5,13-15,21,26,36-38]. Occasionally the tumor mass may transmit the carotid pulse or demonstrate a bruit or thrill [39]. Because of its location in close approximation to carotid vessels and X-XII cranial nerves, tumors enlargement causes progressive symptoms such as dysphagia (two of our cases), odynophagia, hoarseness of voice (two of our cases) or other cranial nerve deficits [2-5,14,26,27,32,37,40]. The patients may give a history suggestive of symptoms associated with catecholamine production such as fluctuating hypertension, blushing, obstructive sleep apnea and palpitations [3-5,10,14,15,21-23,37]. Background. Paraganglioma arising from the carotid body are relatively rare tumors but constitute majority of head and neck paragangliomas (60-70%) [1-6].The term paraganglia was first used by Kohn in the early twentieth century and is the most appropriate nomenclature from an embryologic standpoint [3-5].Other terms such as carotid body tumor, glomus tumor, chemodectomas, and nonchromaffin.

Glomustumoren sind eine heterogene Gruppe von Tumoren, die von einem Glomus (Knäuel) ausgehen.Diese Knäuel können entweder Paraganglien als endokrin aktive Zellknäuel des peripheren Nervensystems (Parasympathikus oder Sympathikus) oder Gefäßknäuel sein.Die Glomustumoren der beiden Paraganglien des Mittelohrs (Glomus tympanicum und Glomus jugulare) sind die häufigsten Tumoren des.

Glomus caroticum - Karotisgabeltumor: an der Karotisgabel; Glomus jugulare: am parasympathischen Paraganglion in der Fossa jugularis; Glomus tympanicum: im Mittelohr, in den Nervus tympanicus eingelagertes Paraganglion; Nervus vagus - vagales Paragangliom: am Foramen jugulare der Schädelbasi Glomus tumors which occur lower in the neck typically arise along a nerve called the vagus nerve, and are known as glomus vagale. These tumors usually are noticed because of a change in the voice caused by injury to the vagus nerve which controls the vocal cord on the side of the tumor. Some patients with glomus vagale tumors present with neck pain. Es handelte sich um 4 typische Glomus-caroticum-Tumoren, um ein Neurinom des Truncus sympathicus und um ein multilokulares zervikales Paragangliom. Ergebnisse: Bei den Glomus-caroticum-Tumoren fand sich farbduplexsonographisch neben einer charakteristischen Aufspreizung der Karotiden mit dazwischenliegendem hypervaskularisiertem Tumorparenchym. Angiography demonstrates an intense tumor blush, with the most common feeding vessel being the ascending pharyngeal 3. Early draining veins are also noted due to intra-tumoral shunting 4.

Ostatní benigní nádory měkkých tkání krku patří v dětském věku mezi rarity: chemodektom z glomus caroticum, neurofibrom, neurilemmom, lipom. 5.1.2. Maligní nádory měkkých tkání krku (mimouzlinové) Vesměs vzácně se vyskytující nádory, které až na výjimky nemají specifickou symptomatologii Paragangliom (tumor glomus caroticum) obyčejně sestává z množství zamotaných cév a tkaniva v uchu nebo těsně kolem a často způsobuje tinnitus. U mladších lidí může pomoct chirurgický zákrok Size of the tumor has a great importance not only for its clinical manifestations but also for treatment. In 1971, Shamblin introduced a classification system based on tumors size [41]. They classified small tumors that could be easily dissected away from the vessels as group I. Group II (7 of our cases) included paragangliomas of medium size that were intimately associated and compressed carotid vessels, but could be separated with careful subadventitial dissection. Group III consisted of (5 of our cases) tumors that were large and typically encased the carotid artery requiring partial or complete vessel resection and replacement. Histologically, carotid body paraganglioma resemble the normal architecture of the carotid body. The tumors are highly vascular, and between the many capillaries are clusters of cells called Zellballen [41]. 124. Kongress der Deutschen Gesellschaft für Innere Medizin e.V.
