How many distinct tumors can exist simultaneously in a unilateral adrenal gland, and are they hormonally active or inactive?

摘要

Primary aldosteronism (PA) is a curable form of secondary hypertension, and the incidence of PA among hypertensives is higher than previously reported., PA manifests endocrinologically and pathophysiologically in various ways, as a form of aldosterone-producing adenoma (APA), idiopathic hyperaldosteronism (IHA), unilateral adrenal hyperplasia (UAH), primary adrenal hyperplasia, adrenal cancer, glucocorticoid-remediable aldosteronism, and as unilateral multiple adrenocortical micronodules (UMN).2 The most common types of PA manifestation are as APA and IHA. APAs typically respond to unilateral adrenalectomy, which corrects hyperaldosteronemia and can attenuate the hypertension.
