POMC and Cowden syndrome 1: Cushing’s syndrome (CS), an endocrinopathy resulting from the prolonged, excessive adrenocortical secretion of cortisol, falls roughly into the following 2 categories: adrenocorticotropic hormone (ACTH)-dependent CS and ACTH-independent CS; the former includes Cushing’s disease that is primarily caused by a pituitary ACTH-secreting tumor and ectopic ACTH syndrome resulting from extrapituitary ACTH-secreting tumors (eg, bronchial carcinoid) [2], while the latter is usually caused by unilateral adenomas or carcinomas that provoke the autonomous adrenal cortical secretion [3].
