Two patients with phaeochromocytoma having atypical biochemical features are described. Total catecholamine excretion was normal in one and only slightly raised in the other; both had a diagnostic rise in output of metadrenaline and 4-hydroxy-3-methoxymandelic acid whilst 4-hydroxy-3-methoxyphenylglycol excretion was increased in one of them. During hypertensive attacks adrenaline excretion became greater than that of noradrenaline. The diagnostic usefulness of separate adrenaline and noradrenaline estimations in addition to catecholamine metabolite assay is discussed. A lack of relationship between tumour catecholamine content and urinary catecholamine output is emphasized.
本文描述了两名具有非典型生化特征的嗜铬细胞瘤患者。其中一名患者的总儿茶酚胺排泄量正常,另一名仅略有升高;两人的间肾上腺素和4-羟基-3-甲氧基扁桃酸排出量均有诊断性升高,而其中一人的4-羟基-3-甲氧基苯乙二醇排泄量增加。在高血压发作期间,肾上腺素的排泄量超过去甲肾上腺素。文中讨论了除儿茶酚胺代谢物检测外,单独测定肾上腺素和去甲肾上腺素的诊断价值。强调了肿瘤儿茶酚胺含量与尿儿茶酚胺排出量之间缺乏相关性。
