Pheochromocytoma – clinical manifestations, diagnosis and current perioperative management [PDF]

, 2019
Pheochromocytoma is a neuroendocrine tumor characterized by the excessive production of catecholamines (epinephrine, norepinephrine, and dopamine). The diagnosis is suspected due to hypertensive paroxysms, associated with vegetative phenomena, due to the

Secondary hypertension: An update on the diagnosis and localisation of a pheochromocytoma or paraganglioma

South African Family Practice, 2021
Most cases of hypertension are because of essential hypertension, however 5% – 15% of cases can be a result of a secondary cause. In this article, we focus on the endocrine causes of secondary hypertension with a particular focus on pheochromocytomas ...

Silent adrenal pheochromocytoma coexistent with corticomedullary hyperplasia: a case incidentally discovered [PDF]

, 2017
Introduction: Pheochromocytoma (PHEO) is a rare catecholamine-producing tumour arising from chromaffin cells in the sympatho-adrenal system, and can present as asymptomatic adrenal incidentaloma (AI). Patient: We describe the case of a 61-year-old woman

Pheochromocytoma: a retrospective study from a single center

Endocrine Regulations, 2021
Objectives. Pheochromocytoma (PCC) is a neuroendocrine tumor derived from chromaffin tissue more frequently found in the adrenal medulla. Many discoveries over the last decade have significantly improved our understanding of PCC.

Urinary and plasma catecholamines and metanephrines in dogs with pheochromocytoma, hypercortisolism, nonadrenal disease and in healthy dogs. [PDF]

, 2015
BACKGROUND: Diagnosis of pheochromocytoma (PC) is based on a combination of clinical suspicion, finding an adrenal mass, increased plasma, and urine concentrations of catecholamine metabolites and is finally confirmed with histopathology.

Unusual presentation of pheochromocytoma

Journal of the Scientific Society, 2014
Pheochromocytomas are rare catecholamine-secreting tumors that arise from chromaffin tissue within the adrenal medulla and extra-adrenal sites. Due to the excess secretion of hormones, these tumors often cause debilitating symptoms and a poor quality-of ...

Pilot quality assurance programme for plasma metanephrines [PDF]

Annals of Clinical Biochemistry: International Journal of Laboratory Medicine, 2010
Background Up to 2007 there was no formal external quality assurance programme for plasma free metanephrines. A pilot programme was conceived by the AACB (Australian Association of Clinical Biochemists) Working Party on biogenic amines. With support from the AACB and Royal College of Pathologists of Australasia Quality Assurance programmes, a pilot ...

The prevalence of resistant arterial hypertension and secondary causes in a cohort of hypertensive patients: a single center experience [PDF]

, 2017
The prevalence of resistant hypertension (RHT) still remains unknown. Aim of the study was to investigate in a large cohort of hypertensive patients the prevalence of RHT, and to identify in these patients the secondary forms of arterial hypertension (SH)

Urinary sampling for 5HIAA and metanephrines determination: revisiting the recommendations

Endocrine Connections, 2017
Context: Biogenic amines such as 5-hydroxy-indole acetic acid (5HIAA) the main metabolite of serotonin or metanephrines (catecholamines metabolites) are used as biomarkers of neuroendocrine tumours.
