Paragangliomas are rare neuroendocrine tumours that arise from extra-adrenal paraganglia
and consist of specialized catecholamine-secreting chromaffin cells.
Lack EE: Tumors of the adrenal gland and extra-adrenal paraganglia
US and European pathologists offer a broad reference to diseases of the endocrine organs--the thyroid, parathyroid, pituitary, adrenal glands and the paraganglia
Cytokine receptors have been identified in the limbic structures of the brain, peripherally in the paraganglia
of the spinal cord, and on lymphocytes.
Paraganglioma originates from chromaffin cells of adrenal medulla and autonomic paraganglia
, which are derived from the neural crest cells.
Paragangliomas are uncommon neuroendocrine tumors, arising from the neural crest-derived paraganglia
of the autonomic nervous system.
They are found in many tissues such as the adrenal medulla, the carotid bodies, the organs of Zuckerkandl, and the paraganglia
of the sympathetic and parasympathetic neurons.
Laryngeal paragangliomas are rare neoplasms that originate in the neural crest cells of the laryngeal paraganglia
Paragangliomas are uncommon neoplasms that can arise in extra-adrenal paraganglia
or in the adrenal medulla, with the latter conventionally classified as pheochromocytomas.
Pheochromocytomas of the urinary bladder probably arise in the paraganglia
of the visceral (autonomic) nervous system, located submucosally either in the dome or in the posterior wall, close to the trigone.
