[Pheochromocytoma. Severe and uncommon presentations]

Area of Science:

• Cardiology
• Endocrinology
• Oncology

Background:

• Phaeochromocytoma is a rare neuroendocrine tumor arising from chromaffin cells, typically in the adrenal medulla.
• It secretes excessive catecholamines, leading to diverse and potentially life-threatening clinical manifestations.
• Cardiovascular complications are a significant concern in patients with undiagnosed phaeochromocytoma.

Observation:

• This report details five cases of phaeochromocytoma presenting with acute cardiovascular emergencies.
• Presentations included myocardial infarction, severe cardiac failure, shock, stroke, and lower limb ischemic gangrene.
• These diverse events highlight the systemic impact of catecholamine excess.

Findings:

• The study discusses the pathophysiology linking catecholamine surges to these critical events.
• It emphasizes that phaeochromocytoma should be considered in patients with unexplained cardiovascular emergencies.
• The findings underscore the potential for catecholamine-induced end-organ damage.

Implications:

• Prompt diagnosis and surgical management of phaeochromocytoma are vital.
• Early intervention can prevent irreversible visceral damage caused by massive catecholamine release.
• This highlights the importance of considering endocrine causes in acute cardiovascular presentations.
