Abstract:
Arterial hypertension is generally classified as primary or essential (90%), and secondary (10%). Infrequent causes of the latter include Cushing's syndrome, classified as ACTH-dependent and independent. A small percentage of ACTH-independent cases are due to ectopic ACTH secretion, generally due to neoplasia, and can present as arterial hypertension and hyperglycaemia that are refractory to pharmacological measures, metabolic alkalosis and hypokalaemia that are difficult to control, but which help guide the initial diagnosis. We present two clinical cases with a diagnosis of ectopic ACTH secretion secondary to small cell lung carcinoma, in which one of the debut manifestations was unknown, difficult to control arterial hypertension.

Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...
