嗜鉻細胞瘤
Also known as PCC, adrenal gland pheochromocytoma, PHEOCHROMOCYTOMA, Pheochromocytoma, Susceptibility to, Pheochromocytoma
Pheochromocytoma (British English: phaeochromocytoma) is a rare tumor of the adrenal medulla composed of chromaffin cells and is a pharmacologically volatile, potentially lethal catecholamine-containing tumor of chromaffin tissue. It is part of the paraganglioma (PGL). These neuroendocrine tumors can be sympathetic, where they release catecholamines into the bloodstream which cause the most common symptoms, including hypertension (high blood pressure), tachycardia (fast heart rate), sweating, and headaches. Some PGLs may secrete little to no catecholamines, or only secrete paroxysmally (episod

嗜铬细胞瘤是由嗜铬细胞所引起的肿瘤。腫瘤位置位於以及肾上腺外系统。90%的腫瘤位于肾上腺髓质，其余发生在肾上腺外嗜铬组织中。此類細胞還能分泌儿茶酚胺，导致出現高血壓、心跳过速以及出汗等临床症状。嗜铬细胞瘤患者年齡大多為20歲至50岁之間。肿瘤一旦擴散，還會造成患者出現耳鸣、听力丧失、呼吸困难和声音嘶哑等症狀。
