Pheochromocytomas and secreting paragangliomas
Catecholamine-producing tumors may arise in the adrenal medulla (pheochromocytomas) or in extraadrenal chromaffin cells (secreting paragangliomas). Their prevalence is about 0.1% in patients with hypertension and 4% in patients with a fortuitously discovered adrenal mass. An increase in the production of catecholamines causes symptoms (mainly headaches, palpitations and excess sweating) and sig...
متن کاملUpdate on Paragangliomas and Pheochromocytomas.
Genomic studies in the recent decades lead to the identification of new genetic mutations that have been shown to play detrimental roles in the formation of pheochromocytoma or paraganglioma. The majority of these genetic mutations detected affect two major cellular pathways - pseudo hypoxic pathway and kinase signalling pathway. Genetic mutations also resulted in syndromes related to paragangl...
متن کاملMolecular markers of paragangliomas/pheochromocytomas
Paragangliomas/pheochromocytomas comprise rare tumors that arise from the extra-adrenal paraganglia, with an incidence of about 2 to 8 per million people each year. Approximately 40% of cases are due to genetic mutations in at least one out of more than 30 causative genes. About 25-30% of pheochromocytomas/paragangliomas develop under the conditions of a hereditary tumor syndrome a third of whi...
متن کاملPheochromocytomas and Paragangliomas: Clinical and Genetic Approaches
Pheochromocytomas (PCCs) and paragangliomas (PGLs) are neuroendocrine tumors derived from the chromaffin tissue. Diagnosis of these tumors is extremely important as they are linked to the hypertension syndrome with great cardiovascular morbidity and mortality. A great majority of PCCs and PGLs are sporadic and benign tumors; however, the classic idea of 10% exception of these features is changi...
متن کاملNovel hereditary forms of pheochromocytomas and paragangliomas.
Pheochromocytomas and paragangliomas are catecholamine-secreting tumors of neural crest origin that arise from the adrenal medulla or extra-adrenal sympathetic paraganglia, respectively. Over the last decade, the extensive genetic heterogeneity of these tumors came to light with the identification of multiple susceptibility genes. These mutations account for at least one-third of pheochromocyto...
