title: [Primary hyperaldosteronism by unilateral adrenal hyperplasia: a report of two cases].
abstract: Primary aldosteronism (PA) is actually the main cause of adrenal-endocrine hypertension. This syndrome is characterized by hypertension, hypokalemia, suppressed plasma renin activity, and increased aldosterone excretion. The most common causes of this syndrome are bilateral idiopathic hyperaldosteronism and aldosterone producing adenoma (Conn's syndrome) and less frequently unilateral adrenal hyperplasia, adrenal carcinoma, or familial hyperaldosteronism. Unilateral adrenal hyperplasia (UAP) constitutes 2% of the causes of PA. We present the case of two patients with UAP.
