[Endocrine hypertension].

Endocrine hypertension is rare, but frequently refractory. Adenomas are common incidental findings. Biochemical tests confirm the diagnosis. Primary aldosteronism is the most common form. Hypokalaemia is an important sign, but 50% of patients may be normokalaemic. The plasma-aldosterone-to-renin ratio is used as a screening test. Medication interferes with the interpretation. Phaeochromocytoma is familial in up to 30% of cases. Cushing's syndrome is an unusual condition which shares phenotypic features with much more common states such as the metabolic syndrome.
