| | Paragangliomas (Dec.1998) |
 | | The incidence of jugulotympanic paragangliomas is approximately 1:1,300,000. | | | Intravagal paragangliomas arise most commonly at the level of the nodose ganglion but may occur at any point along the course of the vagus nerve in the neck. | | | Although the bleeding can be controlled with pressure, the diagnosis of paraganglioma is difficult to make on fine needle aspiration and the cytopathologist usually reports it out as non-diagnostic (mainly because of all the blood in the specimen). |

| | Paraganglioma |
| | In this report, we describe our experience with the histopathology of paragangliomas of the urinary bladder with emphasis on the histologic features that have led to their being misdiagnosed as conventional urothelial cancer and, most importantly, those that will help pathologists recognize this rare tumor of the bladder. | | | It is unclear how mutations induce tumorigenesis and lead to the indolent clinical behavior that often plays a prominent role in treatment strategies. | | | On the basis of our experience, our case is a bona fide primary pulmonary paraganglioma, a tumor heretofore subject to considerable skepticism. |

| | Symptoms of catecholamine excess include hypertension, palpitations or tachyarrhythmias, flushing, headaches, and nausea and are suggestive of a catecholamine-secreting paraganglioma or an associated pheochromocytoma. | | | Paraganglia function as chemoreceptors and are associated with the carotid body, the jugular bulb, and the vagus nerve in the poststyloid PPS. | | | This group consists of patients who are poor surgical candidates and elderly patients with asymptomatic paragangliomas. |

| | The vast majority of head and neck paragangliomas arise from the carorid body, ganglion nodosum, jugoulotympanic paraganglia, or the superior and inferior laryngeal nerves. | | | Head and neck paraganglia occur in association with the carotid body, the ganglion nodosum of the vagus nerve, the middle ear (jugulotympanic paraganglia), and in other rarer sites where paraganglia are known to exist.2 To our knowledge, paraganglia have not been discovered previously in the tongue. | | | Although surgical excision was planned, the patient did not return for the procedure. |

| | The Otology Group - Skull Base Tumors |
| | When the clinical circumstances suggest the diagnosis of lateral skull base disease, in addition to craniocervical paraganglioma, the neurotologic skull base surgeon must produce a differential diagnosis which could foil his treatment plan for glomus tumors. | | | Synchronous lesions must be differentiated from metastatic disease, which is usually identified by occurring in locations other than those from which paragangliomas usually arise. | | | Multiplicity of lesions may complicate surgical planning and must be prospectively identified. |

| | Paragangliomas are often found at other sites, including the middle ear (glomus tympanicum tumor), the carotid body (carotid body tumor), and the vagus nerve in proximity to the inferior (nodosum) vagal ganglion (glomus vagale tumor, glomus intravagale tumor). | | | They are included in a group of tumors referred to as paragangliomas, which occur at various sites and include carotid body, glomus vagale, and glomus tympanicum tumors. | | | Glomus jugulare tumors are rare, slow-growing, hypervascular tumors that arise within the jugular foramen of the temporal bone. |

| | Pheochromocytoma is said to follow the “rule of 10s,” which states that 10% are extra-adrenal (aka paraganglioma), 10% are bilateral, 10% are extra-abdominal, 10% are malignant, 10% are familial (VHL, NF 1, MEN 2A/2B), 10% are pediatric, and 10% are not associated with hypertension. | | | These usually arise in the organ of Zuckerkandl, located at the aortic bifurcation. | | | The remaining 10% are extra-adrenal; the preferred term for extra-adrenal pheochromocytoma is paraganglioma. |
