Surgery will be used to remove the tumor. High blood pressure is the typical symptom of paraganglioma and occurs in less than 0.2% of people with high blood pressure. The development of paraganglioma in unusual regions such as the sella turcica might be due to the presence of remnants of paraganglionic tissue or due . present in any location where autonomic ganglia are found. Pheochromocytoma and paraganglioma are rare neuroendocrine tumors. Call 216.636.1768 Appointments & Locations Contact Us Paravertebral (retroperitoneal) Near the large blood vessels of the head and neck and base of skull. The discovery of susceptibility genes associated with these tumors has led to better understanding of clinical and imaging phenotypes. Adrenal gland disorders occur when the adrenal glands produce too much or too little of these hormones. Prognostic factors. Dr. Pacak has co-authored more than 300 articles, 170 scientific abstracts, and 70 textbook chapters. IMPORTANT: If you have a pheochromocytoma or paraganglioma you need (in, preparation for curative surgery) to be treated with medications until your pheochromocytomas or paraganglioma is removed. Paragangliomas are a type of neuroendocrine tumor found within the larynx, orbit, thyroid gland, nasopharynx, and the neck. The excessive levels of these hormones can cause sweating, a racing heartbeat, feelings of anxiety, headache and high blood pressure. There are two adrenal glands in the human body, which are located on top of the kidneys. The lack of operative complications and uneventful postoperative course support the use of robotic assisted surgery for suitable candidates with such unusual tumors. The most common paraganglioma locations of the head and neck in descending order are the carotid body, jugular, tympanic, and vagal paragangliomas. Thyroid paraganglioma has a strong female predominance, and the mean age of presentation is 48 years. Selected articles Antonio K, Valdez Regional pheochromocytoma or paraganglioma has spread to nearby organs and/or lymph nodes. The most common location in the head and neck is the carotid body, followed by the jugular bulb and vagus nerve. The goal is to obtain stabilization in the blood pressure for 1-2 weeks prior to surgery. Also, he is a reviewer of over 25 international medical journals, including Endocrine Journal, NEJM, JCEM and others. All tumors occurred sporadically and in different locations: abdomen, bladder, thorax, vagal parasympathetic, carotid body parasympathetic, and pheochromocytoma. Common locations for extraadrenal pheochromocytomas include the organ of Zuckerkandl (,,,, Fig 1), bladder wall, retroperitoneum, heart, mediastinum, and carotid and glomus jugulare bodies. These specific nerve cells (chromaffin cells) perform important functions in the body, including regulating blood pressure. SDHD. Most common paraganglioma = pheochromocytoma. The light blue highlighted regions along the spinal cord and around the abdomen, chest, and neck represent ganglia (nerve cluster intersections) of the sympathetic system from which pheochromocytoma and paraganglioma commonly arise. The only exception is the paraganglioma of the adrenal medulla, which is universally known as pheochromocytoma. Karel Pacak, MD, PhD, DSc. The main difference is that pheochromocytoma are found on the adrenal glands, while paraganglioma can be found any where along the sympathetic and para-sympathetic nerve chain. Hereditary paraganglioma-pheochromocytoma is an inherited condition that occurs when benign tumors grow in the paraganglia. A paraganglioma is an abnormal growth of cells that forms from a specific type of nerve cell that's found throughout the body. These tumors can also be called extra-adrenal pheochromocytomas. Surgery is often the treatment of choice and chemotherapy may be suitable in some cases. Scans for pheochromocytoma or paraganglioma is discussed here. The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. The search for susceptibility genes should take both the mode of discovery (incidental vs nonincidental) and tumor location (pheochromocytoma vs paraganglioma) into consideration. Definition: tumour of paraganglion. In most cases, the tumor is benign, but it can be malignant (cancer). PCSK2 expression in neuroendocrine tumors points to a midgut, pulmonary, or pheochromocytoma-paraganglioma origin. By extension, paragangliomas located outside the adrenal gland have been designated as extraadrenal paragangliomas. How we care for PGLs and PCCs Children with PGLs and PCCs are treated at Dana-Farber/Boston Children's Cancer and Blood Disorders Center through our Endocrine-Oncology Program . Imaging plays a critical role in the management of pheochromocytomas and paragangliomas and often guides treatment. 3 Actions to Take. Proponents of surgical treatment for paraganglioma argue from a historic standpoint and cite local control rates of 60% to 72%[30,31] or higher depending on location. 5 The reported . Distributed along prevertebral and paravertebral sympathetic chain and sympathetic nerve fibers innervating retroperitoneum, thorax and pelvis Largest paraganglia: adrenal medulla (bilateral) and organ of Zuckerkandl Can also arise from cervical sympathetic chain, superior cervical ganglion, ciliary ganglion (orbital paraganglioma) Due to the high-risk nature of this surgery, an experienced surgical team and proper pre-operative preparation of the patient are necessary. 602690. Paraganglia are bundles of cells of the peripheral nervous system (the nerves outside the brain and spinal cord). However, paraganglioma in the posterior mediastinum is rare. Prognostic factors. !Benign vascular tumor arising in glomus bodies in the carotid body found between ECA and ICA at carotid bifurcation. An unexpected paraganglioma located in the posterior mediastinum was found during surgery. Rare What is Pheo and Para? The most frequent locations of head and neck paraganglioma are (by decreasing order) carotid body, jugulotympanic and vagal. The . If these biochemical tests indicate a pheochromocytoma or paraganglioma, imaging tests (described below) are used to confirm the diagnosis and determine the location and size of the tumor. The intended audience for the GTR is health care providers and researchers. pathlady01@gmail.com. Paraganglioma treatment most often involves surgery to remove the tumor. Rare, but Not Alone Learn why connecting to a community of patients and specialized doctors matters. But some paraganglioma is found in the adrenal glands. The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. Our clinical team includes healthcare providers who have seen and treated other patients with paraganglioma and pheochromocytoma and are knowledgeable regarding these rare tumors. The term "paraganglioma" is a generic one applied to tumors arising from paraganglia regardless of location [1, 2]. Sites relate to locations of paraganglia. Molecular Genetics In a woman with an extraadrenal paraganglioma, Burnichon et al. Paragangliomas and pheochromocytomas can make . Pheochromocytoma and Paraganglioma Know More, Take Action 3 Unique Dimensions. They release hormones such as noradrenaline or less commonly adrenaline into the bloodstream. Paraganglioma is a rare slow-growing tumor found in 2 out of one million people every year and the prevalence of pheochromocytoma is 1 in 500,000. The doctor may collect blood and urine samples to check for abnormal levels of catecholamines and other substances. There are three different clinical forms of subglottic PGs: intraluminal (tracheal PGs), extraluminal (thyroid PGs) and the mixed type (both intraluminal and extraluminal, mixed-subglottic PGs). . Symptoms include high blood pressure and headaches, though you could experience no symptoms. The largest cluster of cells is found within the adrenal medulla, with smaller collections in the paravertebral space, and head and neck region. When the same type of tumor is found in the adrenal gland, they are referred to as a pheochromocytoma. Paraganglioma tumor locations Note: Pheochromocytomas arise in the medulla of the adrenal gland, whereas sympathetic paragangliomas arise along the sympathetic chains in the pelvis, abdomen, and chest. How common is paraganglioma? This is called localization. (2010) identified a heterozygous germline mutation in the SDHA gene (R589W; 600857.0005 ). Hereditary paraganglioma-pheochromocytoma syndrome is a condition in which tumors develop in structures called paraganglia. and are found when imaging such as a CT scan or MRI is performed for an unrelated reason or because the tumour is in a location that can be seen or felt. In summary, we report a very rare location of paraganglioma and the first one to be managed by robotic assisted partial nephrectomy. However, the distinction between pheochromocytoma and paraganglioma is an important one because of implications for genetic testing, risk stratification, and treatment. It can also form on either side of the spine. Paragangliomas , also called glomus tumors, occur in a variety of places in the head and neck. They are rare tumors, with an overall estimated incidence of 1/300,000. Subglottic paragangliomas (PGs) are exceptionally rare and unpredictable, occasionally presenting at an atypical location. Functional imaging is of prime importance because of its sensitivity and specificity in subtypes of pheochromocytoma and paraganglioma. Intracerebral location of paraganglioma is rare, with cases being reported in the sella, cerebellopontine angle, penial body, frontal skull base, petrous ridge, sylvian fissure and cerebellum . However, the clinical value and usefulness of . pathlady01@gmail.com. The medulla produces catecholamines (epinephrine, norepinephrine, and dopamine). A paraganglioma is a type of neuroendocrine tumour. Approximately 85% of paragangliomas are in the abdomen, 12% are found in the chest, and only about 3% are in the head and neck. ! Almost half of all paragangliomas appear in the bone on the side of the head/skull (temporal bone). Most (about 65-90%) of paragangliomas are non-cancerous tumours. 3 Most patients are asymptomatic, with a nonfunctional thyroid nodule for several years discovered incidentally with radiographic imaging. Paraganglioma is a rare entity with wide age and anatomic distribution and variable cytomorphological features that often overlap with those of malignant neoplasms. Malignant Paraganglioma I have malignant Paraganglioma because I have many metastases. A type of paraganglioma (glomus paraganglioma) in the middle ear may lead to hearing loss and tinnitus. A number sign (#) is used with this entry because paraganglioma and gastric stromal sarcoma can be caused by germline mutation in the SDHB gene (185470) on chromosome 1p36, the SDHC gene (602413) on chromosome 1q23, and the SDHD gene (602690) on chromosome 11q23. However, some may behave more like a cancer by spreading to other parts . The term "paraganglioma" is a generic one applied to tumors arising from paraganglia regardless of location [1, 2]. Treatment options depends on the type, location and stage of the paraganglioma. We report on an original case of a 64 year old lady diagnosed with an extraadrenal mesenteric paraganglioma associated with an incidental histological finding of a gallbladder paraganglion. However, because paraganglioma release adrenaline in uncontrolled bursts, they can cause serious health problems like stroke, heart attacks, and even death. The intended audience for the GTR is health care providers and researchers. Paraganglioma are found in 2 out of every million people each year and is the cause of high blood pressure in less than 0.2% of people with high blood pressure. Possible aggressive behavior such as recurrence and metastasis to lymph nodes, bone, and lung as well as Succinate Dehydrogenase complex mutations warrant an accurate diagnosis on . Pheochromocytoma Paraganglioma Carotid Body Tumor Neuroendocrine Tumors Neuroectodermal Tumors Neoplasms, Germ Cell and Embryonal: Neoplasms by Histologic Type Neoplasms Neoplasms, Nerve Tissue Paraganglioma, Extra-Adrenal Lanreotide Antineoplastic Agents Features most predictive of malignancy: extra-adrenal location, coarse nodularity of tumor, confluent tumor necrosis, absence of hyaline globules ( Hum Pathol 1990;21:1168 ) Appointments 216.444.6568 The adrenal glands, located on the top of each kidney, are responsible for releasing different hormones. Methods. Mostly benign behavior. If metastases, call "malignant paraganglioma", which may show reduced sustentacular cells and decreased neuropeptide markers. AZEDRA ® (iobenguane I 131) is a prescription medicine used to treat adult and pediatric patients 12 years and older with cancers known as pheochromocytoma and paraganglioma that are positive for the norepinephrine transporter (as determined by an iobenguane scan), and who require systemic anticancer therapy. Locations of paraganglia. pathlady01@gmail.com. Paraganglioma in the head and neck are less likely to be metastatic than tumors in the chest, abdomen and pelvis. A paraganglioma is a rare but treatable neuroendocrine tumor that usually forms along major blood vessels and nerve pathways in your neck and head. 4 In the few symptomatic patients, their presentation ranged from an anterior neck mass, dysphagia, dyspnea, stridor, and hemoptysis. In this case, the features of a liver lesion and paraganglioma overlapped but due to the location, a primary liver lesion was the most likely diagnosis. !Catecholamine-secreting carotid body paraganglioma is rare. Tumor was removed with surgery but it grew back, very aggressive and little by little I've been having new tumors on my neck, lungs, bones (spine, pelvis, femur, clavicle, etc. 2 Approximately, 70% of the sympathetic paragangliomas occur in the abdomen, whereas the other 30% occur in the chest. Paragangliomas more often arise in female patients, usually in the 4th and 5th decades of life (Kimura et al., 2004). Tumors tend to invade bordering structures and may also form metastasis. Localized pheochromocytoma or paraganglioma is usually treated with surgery to remove the tumor. The paraganglioma from the head and neck, and sometimes other locations, are silent meaning they do not produce high epinephrine or norepinephrine. If PCSK2 is used in an antibody panel, it appears to indicate the primary tumor location, particularly those with a midgut, pulmonary, or pheochromocytoma‐paraganglion origin. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. Typically not, but some may appear as swelling in the neck.

Here you can find a diagram of the human body with common sites of pheochromocytoma/paragnagliomas. Can You Feel a Paraganglioma? Treatment for paraganglioma is surgical resection. 3 Department of Laboratory Medicine and Pathobiology, University of Toronto, Toronto, ON M5S 1A8, Canada. The anesthesia management of this patient was challenging. Presenting symptoms are related to catecholamine hypersecretion or to a mass effect. Pheochromocytoma and Paraganglioma Pheochromocytoma and paraganglioma are related tumors that differ mainly in location; pheochromocytomas are adrenal, and paragangliomas can be anywhere else. The only exception is the paraganglioma of the adrenal medulla, which is universally known as pheochromocytoma. !Most common in the 4th and 5th decade. A PGL arising from the adrenal gland is called pheochromocytoma (PHEO). Before any mets, it was a glomus jugulare tumor in my head, around the ear area. If the tumor is in an adrenal gland, then the whole gland may be removed. Medication can be taken to normalize blood pressure and heart rate if this is an issue. Paraganglioma cells commonly secrete hormones known as catecholamines, including adrenaline, which is the fight-or-flight hormone. When chromaffin cells become abnormal they can form growths (tumors). ! Some studies indicate that paragangliomas are found in only two out of every one million people each year. A tumor involving the paraganglia is known as a paraganglioma. 1 Department of Pathology, University Health Network, Toronto, ON M5G 2C4, Canada. Surgery is typically difficult (due to the characteristic involvement of intracranial structures) and bloody (due to the structural nature of the tumor). Paraganglioma can be found in a wide range of locations. These tumors are usually misdiagnosed as other relatively common primary . Paraganglia are clusters of neuroendocrine cells dispersed throughout the body and closely related to the autonomic nervous system, with either parasympathetic or sympathetic function. Conflict of Interests Paraganglioma and gastric stromal sarcoma. Paraganglia are clusters of neuroendocrine cells found throughout the body in close relation to the autonomic nervous system and work in either a parasympathetic or sympathetic manner. Features most predictive of malignancy: extra-adrenal location, coarse nodularity of tumor, confluent tumor necrosis, absence of hyaline globules ( Hum Pathol 1990;21:1168 ) Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. There are two types of paragangliomas . As the understanding of pheochromocytomas and paragangliomas have evolved beyond the "10 percent rule" (ie, 10 percent familial, 10 percent malignant, 10 percent extra-adrenal . The adrenal medulla has the biggest group of cells, followed by the paravertebral space, head, and neck region. Advertisement This can cause episodes of high blood pressure, a rapid heartbeat, sweating, headache and tremors. ! The nerve cells involved in paraganglioma are part of the peripheral nervous system, meaning the part of the nervous system outside of the brain and spinal cord. By extension, paragangliomas located outside the adrenal gland have been designated as extraadrenal paragangliomas. Paragangliomas are rare neuroendocrine, neural crest-derived tumours, found in diverse locations and display variable catecholamine secreting behaviour. 3. Hereditary paraganglioma-pheochromocytoma is an inherited condition characterized by the growth of tumors in structures called paraganglia.

Can be sympathetic or parasympathetic. paraganglioma syndrome succinate dehydrogenase mutations von Hippel-Lindau syndrome ( vHL) Location They are divided according to location: carotid body tumor (or chemodectoma) located at the carotid body, and splaying the carotid bifurcation most common paraganglioma of the head and neck (60-67% of total) glomus tympanicum paraganglioma Approximately 15-20% occur outside of this area in the chest, heart, abdomen, pelvis, bladder, and/or neck or base of the skull. If metastases, call "malignant paraganglioma", which may show reduced sustentacular cells and decreased neuropeptide markers. Each adrenal gland has two parts, the outer cortex and inner medulla. Some times. 1. We looked for clinical variables that suggested potential heritable disease, namely, (1) a family history of pheochromocytomas and paragangliomas, (2) younger than 40 years at diagnosis, (3) more than 1 pheochromocytoma or paraganglioma, (4) tumor location outside the adrenal glands, and (5) malignant tumors. Jugular Paraganglioma Also known as: glomus jugulare paraganglioma, glomus jugulotympanicum paraganglioma, jugular foramen paraganglioma, chemodectoma Benign tumor arising from neural crest cells near the jugular foramen Look for bony erosion on CT and "salt and pepper" appearance on T1 and T2 MR Can arise from three distinct locations: the jugular bulb, the tympanic branch of This figure shows where paraganglioma can be found.
