متن کاملDopamine-secreting phaeochromocytomas and paragangliomas: clinical features and management.
Most functional phaeochromocytomas/paragangliomas produce noradrenaline and/or adrenaline. Those that produce dopamine are rare. We describe the distinguishing clinical features of dopamine-secreting phaeochromocytomas and paragangliomas from those that secrete noradrenaline/adrenaline and the impact on their management. We present a case of a dopamine-secreting paraganglioma from our instituti...

Catecholamine-producing tumors may arise in the adrenal medulla (pheochromocytomas) or in extraadrenal chromaffin cells (secreting paragangliomas). Their prevalence is about 0.1% in patients with hypertension and 4% in patients with a fortuitously discovered adrenal mass. An increase in the production of catecholamines causes symptoms (mainly headaches, palpitations and excess sweating) and sig...
