چکیده
The adrenal glands have had a long and complex history, and for many years, different schools of anatomy doubted their very existence. Although some authors suggested that the first description of the glands occurred in the Bible (Leviticus 3:4), most authorities credit Bartholomeus Eustachius (1520-1574) with the discovery of the adrenal glands in humans. In his great work, Opuscula Anatomica, Eustachius (1552) provided the following description of the adrenals which he referred to as glandulae renibus incumbentes:

Histopathology and immunohistochemistry of adrenal medullary tumors and paragangliomas.
Paragangliomas arise from sympathetic or parasympathetic paraganglia and should now be defined by their site and type. The term pheochromocytoma is reserved for intra-adrenal tumors. This short review discusses the gross and microscopic features, the immunohistochemical profile, the problem of recognizing malignant potential, and the rare instances where a differential diagnosis has to be consi...
متن کاملParaganglioma: Carotid Body Tumor
Extra-adrenal paragangliomas are neoplasms of the paraganglia located within the paravertebral sympathetic and parasympathetic chains. Thus paragangliomas may arise anywhere along these tracts and common sites of occurrence include abdomen, retroperitoneum, chest and mediastinum and various head and neck locations such as jugulotympanic membrane, orbit, nasopharynx, larynx, vagal body and carot...
متن کاملBilateral pheochromocytoma with ganglioneuroma component associated with multiple neuroendocrine neoplasia type 2A: a case report
BACKGROUND Composite pheochromocytoma/paragangliomas are very rare tumors composed of ordinary pheochromocytoma paragangliomas associated with neurogenic tumors. Several hereditary susceptibility disorders are known to be associated with pheochromocytoma/paragangliomas such as multiple endocrine neoplasia type 2 (2A or B). To the best of our knowledge, only four cases of composite pheochromocyt...
متن کاملCytokeratin expression in adrenal phaeochromocytomas and extra-adrenal paragangliomas.
AIM To examine whether adrenal phaeochromocytomas and extra-adrenal paragangliomas are immunoreactive for commercially available and routinely used cytokeratin antibodies. METHODS 18 extra-adrenal paragangliomas and seven adrenal phaeochromocytomas were stained with CAM 5.2, AE1/3, and 34 beta E12 following microwave antigen retrieval of formalin fixed tissue. RESULTS A single case from the...
متن کاملFamilial paraganglioma: a novel presentation of a case and response to therapy with radiolabelled MIBG.
Phaeochromocytomas (PC) and paragangliomas are disorders of the sympatho-adrenomedullary system. They are chromaffin-containing neuroendocrine tumors of neural crest origin that contain catecholamine-secreting granules: they arise from either the adrenal medulla (phaeochromocytomas) or from extra-adrenal neural crest derivatives e.g. the sympathetic chain (paragangliomas). The term paragangliom...
