Cortisol secretion in ACTH-independent primary adrenal Cushing's syndromes was previously
believed to be autonomous. In most cases, the pathophysiology of the disease was largely
unknown. However, recent work by our group and others have shown that these cortisol-producing
adrenocortical tumors may be under the control of inappropriate, illicit or ectopic
hormone receptors. This review provides a rapid overview of the physiology of the
normal adrenal cortex and outlines recent findings supporting the hypothesis that
cortisol production may be regulated by a diversity of abnormal or ectopic hormone
receptors in primary adrenal Cushing's syndrome.
