Ectopic secretion of corticotropin-releasing factor as a cause of Cushing's syndrome. A clinical, morphologic, and biochemical study.
New England Journal of Medicine 1984 July 6
Corticotropin-releasing factor, a hypophyseo-tropic hormone that stimulates adrenocorticotropic hormone (ACTH) secretion, has recently been isolated, characterized, and synthesized in the sheep and rat. We report on a patient with metastatic carcinoma of the prostate presenting with anterior and posterior pituitary hormone deficiency together with ACTH-dependent Cushing's syndrome. At postmortem examination, large areas of the median eminence and pituitary stalk were replaced by tumor, but the corticotrophs were markedly hyperplastic. Immunostaining of tumor cells was positive for corticotropin-releasing factor and was negative for ACTH and a wide range of other hormones. Radioimmunoassay and bioassays showed that tumor extracts and further purified fractions were active in corticotropin-releasing factor, and the tumor material coeluted with corticotropin-releasing factor on high-pressure liquid chromatography. These studies demonstrate that ectopic secretion of corticotropin-releasing factor is a cause of Cushing's syndrome in human beings. The features of this syndrome include hypercortisolism, pituitary corticotroph hyperplasia, elevation of circulating ACTH levels, and failure to suppress the pituitary-adrenal axis with exogenous glucocorticoids.
