Cushing syndrome (CS) is a rare condition, with an incidence of 2 to 4 cases per million inhabitants per year. In most cases of CS, elevated adrenocorticotropic hormone (ACTH) secretion results in excess adrenal gland cortisol secretion but usually this is from pituitary, not ectopic ACTH production. We present a ...

Cushing's syndrome (CS), first described by the neurosurgeon Harvey Cushing in the 1930s, is the result of chronic glucocorticoid excess. In patients with adreno-corticotropic hormone (ACTH)-dependent CS, bilateral hyperplasia of the adrenal cortex occurs, while in those with ACTH-independent primary CS, either adrenocortical tumors or primary adrenal hyperplasia can be ...
