Diagnostic and therapeutic problems in a patient with ectopic ACTH syndrome caused by a malignant bronchial adenoma are discussed. Persistent Cushing's syndrome was present following apparent total adrenalectomy, but radioactive scanning with 131I-19-iodocholesterol showed the presence of residual adrenal tissue in the right suprarenal bed. Amelioration of the hypercortisolism occurred after removal of the bronchial adenoma. A paradoxical elevation of adrenocortical activity followed administration of dexamethasone and data are presented which suggest that periodic secretion of ACTH accounted for this phenomenon.
