phaeochromocytoma
Let an agent explain phaeochromocytoma and paraganglioma, relay symptoms, genetics, diagnosis and general treatment from endocrinology sources, describe the tumour sites the registry aliases name, and distinguish these tumours from other adrenal tumours, from anxiety or panic and from essential hypertension, routing crises to emergency care.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain phaeochromocytoma and paraganglioma, relay symptoms, genetics, diagnosis and general treatment from endocrinology sources, describe the tumour sites the registry aliases name, and distinguish these tumours from other adrenal tumours, from anxiety or panic and from essential hypertension, routing crises to emergency care.
A rare neuroendocrine tumour of the adrenal medulla that produces catecholamines such as adrenaline and noradrenaline, causing episodes of high blood pressure, headache, sweating and palpitations, closely related to paragangliomas, which arise from extra-adrenal paraganglia in the abdomen, retroperitoneum or head and neck, such as the glomus jugulare tumour; many cases are hereditary, and although often classed as benign, all such tumours are now considered to have metastatic potential. A hypertensive crisis needs emergency care. The model routes people to clinicians.
What it is for: Not applicable; a tumour.
It can be route crises first; explain tumour and symptoms; relay diagnosis and treatment; distinguish related conditions.
Distinguishing features
Catecholamine excess
Episodic symptoms
Strong genetic link
Adrenal or extra-adrenal
What it looks like
Not a visible object; an adrenal or paraganglion mass.
Physical character
incidence: about 2-8 per million per year - estimates
hereditary share: about 30-40 percent
classic triad: headache, sweating, palpitations list
WHO 2017: all considered potentially metastatic note
How it is recognised
Catecholamine-producing neuroendocrine tumour
Adrenal phaeochromocytoma, paraganglioma, extra-adrenal retroperitoneal paraganglioma, glomus jugulare tumour
Adrenal adenomas are usually non-functioning; panic attacks lack a tumour; essential hypertension has no single cause
