WebIntroduction: 10% of corticotrophin (ACTH)-dependent Cushing's syndrome arises from secretion by extrapituitary tumours, with phaeochromocytoma implicated in a few cases. Ectopic secretion by phaeochromocytoma of corticotropin-releasing hormone (CRF), with secondary corticotroph hyperplasia, is even rarer, with only five cases in the literature … WebThe time course of CRF secretion in response to this stimulus parallels that of epinephrine secretion. The physiological significance of adrenal medullary CRF remains to be determined. Although CRF has been shown to affect catecholamine secretion, the peptide appears to be only a weak secretagogue for catecholamines.
