Miller 1 Langenbeck's Archives of Surgery volume 397, pages 247–253 (2012)Cite this article Local recurrence and new primary tumors may occur at any site where paraganglion tissue exists, while common sites of extra-adrenal pheochromocytoma metastases include the regional lymph nodes, bone, liver and lungs.27,77,144 Determination of the site of new primary or metastatic disease is probably best achieved with 131I-MIBG scintigraphy when available.24,112,119,120,125,144 In … Histopathological exam- echolamines and their metabolites. Further, MRI abdomen revealed 4.1 cm right adrenal mass. This may be very variable but include. Which of the following tissues is most likely the site for an extra-adrenal pheochromocytoma? Here, we report the case of an extra-adrenal abdominal pheochromocytoma initially manifesting as haemoptysis/dyspnoea during exercise without classic symptoms. At Rare Disease in Washington DC, we talked with Brian Wood about the years of being unable to properly get a diagnosis of extra adrenal pheochromatocytoma. [1][1] Extra-adrenal pheochromocytoma (EAP They may be malignant in up to 40% of the cases, though conflicting data add to the uncertainty of this point. being diagnosed as extra-adrenal pheochromocytoma. Continuity of the diagnosis of extra-adrenal pheochromocytoma is established ureter was established with spatulated end-to-end anastomo- by biochemical examination of plasma and urinary cat- sis. Goldstein RE, O'Neill JA Jr, Holcomb GW 3rd, et al. Our patient had no signs of recurrence during the 5-year follow-up period after surgery. Namimoto et al. Nonchromaffin paragangliomas are usually named based on the primary anatomical site … Pulmonary manifestations of pheochromocytoma are infrequent and are not well documented. Because of the excess secretion of hormones, these tumors often cause debilitating symptoms and a poor quality of life. Pheochromocytoma: presentation, diagnosis, and treatment. Extra-adrenal pheochromocytoma has been previously reported to account for ~10% of all pheochromocytoma cases during adulthood and for 30-40% of cases in … Metastatic pheochromocytoma is defined as the presence of tumor cells (chromaffin tissue) where they are not normally found. Extra-adrenal pheochromocytoma (EAP) is a rare cause of secondary hypertension in adults. Here's a look at the extra-adrenal sites (locations NOT in the adrenal--and therefore called "paragangliomas": ... to ensure you do not have a pheochromocytoma. Hamidi O, Young WF Jr, Iñiguez-Ariza NM, … Hypertension 1997; 29:1133. The most common sites of metastasis for pheochromocytoma or extra-adrenal paraganglioma are lymph nodes, bones, lungs, and liver. The most common site of occurrence of extra-adrenal pheochromocytoma is the superior para-aortic region between the diaphragm and lower renal … J Surg Oncol 2005; 89: 193 – 201. Pheochromocytoma is a catecholamine-secreting tumour that leads to various symptoms. Laboratory testing showed high total plasma. Paraganglioma: not just an extra-adrenal pheochromocytoma. Correspondence Address: Percy Jal Chibber Department of Urology, Sir J J Hospital, Byculla, Mumbai - 400 008 India . kidney. 2 Arising wherever chromaffin cells of the paraganglionic system are located (from skull base to bladder), more than 85% of these tumors occur in the retroperitoneum. A MEDLINE search in the English language revealed no cases of endobronchial involvement from a pheochromocytoma. A Islets of Langerhans. Hypertension with an adrenal incidentaloma. In adults, pheochromocytomas are often called the "10% tumor" because approximately 10% occur above the diaphragm, 10% of intraabdominal pheochromocytomas are extra-adrenal, 10% are bilateral, 10% are multiple, 10% are … Source of Support: None, Conflict of Interest: None [SCOPUS][CROSSREF][PUBMED] Keywords: Pheochromocytoma; Extra-Adrenal … Extra-adrenal pheochromocytoma: diagnosis and management Curr Urol Rep. 2007 Jan;8(1):83-8. doi: 10.1007/s11934-007-0025-5. About 90% of pheochromocytomas arise within the adrenal glands and about 98% arise within the abdomen. Extra-adrenal pheochromocytoma is a rare neuroendocrine tumor that produces stores and secretes catecholamines. adrenal pheochromocytoma (P) posterior to inferior versa cava and anteromedial to upper pole of right ft of aorta at level of L3. More than 85% of the tumours are infradiaphragmatic in location, with para-aortic region being the most common site. It may arise in any portion of paraganglion system, though they most commonly occur below the diaphragm, usually in the organ of Zuckerkandl. Extra-adrenal pheochromocytoma. Extra-adrenal pheochromocytoma constitutes 15% of adult and 30% of pediatric pheochromocytomas. B Lymph node. EAPs probably represent at least 15% of adult and 30% of childhood phenochromocytomas, as opposed to the traditional teaching that 10% of all pheochromocytomas are at extra-adrenal sites. Patients with a paraganglioma are more likely to develop metastases than those with a pheochromocytoma. While medical management plays a significant role in the treatment of pheochromocytoma patients, surgical ex-cision remains the only cure. J Urol 1992; 147:1. Using the current low-density CT criteria for diagnosing adrenal adenoma can be misleading because it has been reported that pheochromocytomas can have low attenuation values similar to those of adenomas [ 17 ]. High adrenaline “spells”. Distinct from paraganglioma / extra-adrenal pheochromocytoma, which arises from chromaffin cells of sympathetic ganglia. Chromaffin paras are rarer than pheo, but have a higher chance of malignancy (cancerous). Clinical experience over 48 years with pheochromocytoma. References ↵ Elder EE, Elder G, Larsson C. Pheochromocytoma and functional paraganglioma syndrome: no longer the 10% tumor. The main risks are related to operative difficulties. ... as opposed to the traditional teaching that 10% of all pheochromocytomas are at extra-adrenal sites. Convalescence was uneventful. Extra-adrenal pheochromocytomas (EAPs) may arise in any portion of the paraganglion system, though they most commonly occur below the diaphragm, frequently in the organ of Zuckerkandl. Patients with known or suspected malignancy should undergo staging with computed tomography or magnetic resonance imaging as well as functional imaging (e.g., with iodine I 123-metaiodobenzylguanidine [MIBG]) to determine the extent and location … Chromaffin paragangliomas arise from chromaffin cells, and are sometimes called extra-adrenal pheochromocytoma, which means the tumor is found outside the adrenal gland. Pheochromocytoma is an uncommon neuroendocrine tumour arising from the chromaffin cells associated with increased catecholamine production. Histological examination at that time demonstrated an extra-adrenal pheochromocytoma. She presented with symptoms of wheezing and a … Pheochromocytoma (intra-adrenal); Paraganglioma (extra-adrenal) 1. The most common extra-adrenal sites of metastases are the lymph nodes, lung, liver, and bone. This confirmed the diagnosis of adrenal pheochromocytoma. Both adrenal and extra-adrenal paragangliomas display similar histopathological characteristics. Paraganglioma: not just an extra-adrenal pheochromocytoma Paraganglioma: not just an extra-adrenal pheochromocytoma Laird, Amanda; Gauger, Paul; Doherty, Gerard; Miller, Barbra 2011-11-17 00:00:00 Langenbecks Arch Surg (2012) 397:247–253 DOI 10.1007/s00423-011-0871-y ORIGINAL ARTICLE Amanda M.

Unusual sites in the abdomen and pelvis include kidney, urethra, prostate, spermatic cord, genital tract, and liver. Endocrine Pathology. Factors that increase the chances of malignancy include extra-adrenal pheochromocytomas (35% are malignant) and large tumors (>5 cm more likely to be malignant). In the case of a high adrenal 18 F-FDG uptake (tumor-to-liver maximal SUV ratio > 2), 4 main potential differential diagnoses should be considered: pheochromocytoma, malignant adrenal cortex tumor, primary lymphoma, and metastasis. Extra-adrenal pheochromocytoma - a case report Sharad H Somani, Jagdish B Bhawani, Percy Jal Chibber Department of Urology, Sir J J Hospital, Mumbai, India. What every clinician should know Clinical features and incidence. EAP is a completely curable disease, if diagnosed early and treated adequately. 1 It most commonly occurs in the second or third decade of life with a slight male preponderance. Pheochromocytoma may also be referred to as adrenal paraganglioma. renal medulla and extra-adrenal sites. In one study of patients with pheochromocytoma or secretory extra-adrenal paraganglioma, the 5-year likeli-hood of recurrence among those with an extra-adrenal paraganglioma was approximately 20% [14]. In contrast, when urine or plasma epinephrine levels represent more than 20% of the total catecholamine level, it is likely that the pheochromocytoma is of adrenal origin (2). We report a case of endobronchial metastases in a 37-year-old woman known to have a recurrent extra-adrenal pheochromocytoma. These tumors usually secrete hormones like pheo. have reported 100% sensitivity for differentiating pheochromocytoma from adrenal adenomas, on the basis of lack of dropout of signal intensity on opposed-phase images. BACKGROUND: Extra-adrenal pheochromocytoma, or paraganglioma, is a rare tumour arising from paraganglion chromaffin cells of the sympathetic nervous system. C Paraganglia. Palpitation (heart racaing and pounding). A Liver. Extra-Adrenal Pheochromocytoma: An Unusual Location By Gary E. Hartman, Raymond Hintz, William Northway, Jr, and Frederick G. Mihm Stanford, California A 14-year-old boy with a retrohepatic para-aortic pheochromocytoma demonstrates the potential difficulties of localization in an unusual extra-adrenal site of pheochro- mocytoma. This adrenal incidentaloma was not visualized on imaging done 5 years ago. metanephrines: 890 pg/ml (< or = 205), 24-hour urine metanephrines: 2337 (140–785), A1C: 10%. Since head and neck paragangliomas rarely secrete catecholamines these tumors mostly do not require preoperative treatment. Because extra-adrenal sites lack phenylethanolamine N-methyltransferase, these tumors secrete norepinephrine whereas epinephrine is the main hormone secreted from adrenal pheochromocytomas ; Schwartz says : The scans should be performed without contrast to minimize the risk of precipitating a hypertensive crisis although some recent studies suggest that IV contrast may … Ann Surg 1999; 229:755. Difficult extra-adrenal operative sites include tumors located in the bladder, the chest or the head and neck [Manger, 2006]. Extra-adrenal pheochromocytomas (EAPs) may arise in any portion of the paraganglion system, though they most commonly occur below the diaphragm, frequently in the organ of Zuckerkandl. EAPs probably represent at least 15% of adult and 30% of childhood phenochromocytomas, as opposed to the traditional teaching that 10% of all pheochromocytomas are at extra-adrenal sites. Hypertension at a young age ( 50 years of age). Haemoptysis is rarely caused by a pheochromocytoma occurring outside the bronchus or thoracic cavity. Common extra-adrenal sites are the organ of Zuckerkandl (a), urinary bladder wall, retroperitoneum, heart, mediastinum, as well as carotid and glomus jugulare bodies (7).
