Corticotropin-dependent Cushing's syndrome in older people: presentation of five cases and therapeutical use of ketoconazole.
Cushing's syndrome is a rare disorder. The corticotropin (ACTH)-dependent form of this syndrome generally results either from excessive ACTH secretion by a pituitary adenoma or ectopic secretion by a malignant tumor. Theoretically, the latter type can be assumed to occur more frequently in old age as the incidence of malignancy increases. ⋯ Pituitary-dependent Cushing's disease may occur more frequently in patients older than 75 years of age than has previously been assumed. Because surgical treatment is not always easily tolerated by older patients, the steroidogenesis inhibitor, ketoconazole, can be a valuable alternative for the control of hypercorticism.
