Pheochromocytoma paraganglioma
-
Pheochromocytoma (PCC) and paraganglioma (PGL) are neuroendocrine tumors originating from chromafn cells capable of producing catecholamine hormones. The new presentation of pheochromocytoma or paraganglioma in pregnancy is very rare and can be life-threatening for mother and child.

Abdominal nonfunctional paraganglioma is rare. Malignant potential of paraganglioma is assessed by Grading of Adrenal Pheochromocytoma and Paraganglioma score and genetic testing, but genetic testing is not common.

Pheochromocytomas (PCC) and paragangliomas (PGL) are catecholamine-producing neuroendocrine tumors. According to the World Health Organization Classification 2017, all PCC/PGL are considered to have malignant potential.

Surgical manipulation of pheochromocytomas and paragangliomas (PPGLs) may induce large hemodynamic oscillations due to catecholamine release. Little is known regarding hemodynamic instability during percutaneous ablation of PPGLs. We examined intraprocedural hemodynamic variability and postoperative complications related to percutaneous ablation of extra-adrenal metastases of PPGL.

Dramatic hemodynamic fluctuation occurs frequently during surgery for pheochromocytoma or paraganglioma. However, the criteria of intraoperative hemodynamic instability vary widely, and most of them were defined arbitrarily but not according to patients’ prognosis.

Paraganglioma can be found in a wide range of locations. However, paraganglioma in the posterior mediastinum is rare. An unexpected paraganglioma located in the posterior mediastinum was found during surgery. The anesthesia management of this patient was challenging.

Preoperative intravenous rehydration for patients with pheochromocytomas and paragangliomas (PPGLs) is widely used in many medical centers, but its usefulness has not been well evaluated. The objective of this study was to compare the perioperative hemodynamics and early outcome between patients who received preoperative intravenous rehydration and those without for resection of PPGLs.

Pheochromocytomas (PCC) và Pragangliomas (PLG) là những khối u thần kinh – nội tiết. Khối u tiết catecholamine xuất phát từ tủy thượng thận được gọi là Pheochromocytoma. Khối u có nguồn gốc ngoài thượng thận, có thể tiết catecholamine hoặc không có chức năng, bắt nguồn từ các hạch thần kinh giao cảm hoặc phó giao cảm được gọi là Paraganglioma.

Succinate dehydrogenase subunit B (SDHB) mutations are associated with aggressive pheochromocytoma (PHEO)/paraganglioma (PGL) behavior, often resulting in metastatic disease and fatal outcomes. These tumors are often larger, extra-adrenal, and contain lower catecholamine concentrations than other hereditary PHEOs/PGLs.

Germline mutations in genes encoding subunits of succinate dehydrogenase (SDH) are associated with the development of pheochromocytoma (PC) and/or paraganglioma (PGL). As assembly factors have been identified as playing a role in maturation of individual SDH subunits and assembly of the functioning SDH complex, we hypothesized that SDHAF3 variants may be associated with PC/PGL and functionality of SDH.

Paragangliomas là các khối u thần kinh nội tiết nằm ở các hạch thần kinh có nguồn gốc từ mào thần kinh trong giai đoạn phôi thai, khi khối u này nằm ở tủy thượng thận (được xem như là một phần của hệ thần kinh giao cảm) nó có tên gọi là pheochromocytomas.

Giải thích về thuật ngữ Pheochromocytoma và paraganglioma Những khối u xuất phát từ những tế bào ưa crôm (cromaffin cell) ở bên trong tủy thượng thận hay ở hạch giao cảm hoặc phó giao cảm được gọi chung là pheochromocytomas và paragangliomas. Tuy có nhiều cách gọi tên những u này nhưng hầu hết đã đồng ý sử dụng thuật ngữ pheochromocytoma để tả những khối u tiết catecholamine có triệu chứng, bao gồm cả những khối u nằm ở ngoài tuyến thượng thận, ở chậu hông, ở lồng ngực. Còn thuật ngữ paraganglioma dùng tả khối u...
