Phaeochromocytoma.

Phaeochromocytomas are rare catecholamine-secreting tumours which can mimic a variety of common clinical conditions, such as hypertension and angina. It is a potentially curable condition if discovered early, and clinicians should be alerted as to its presence in a young individual with hypertension or atypical angina-associated hypertension. Pharmacological mismanagement can cause fatal hypertensive crisis.
