Ectopic hormone production by malignant tumors.
Malignant tumours of nonendocrine tissues may produce ectopic hormones. The most likely mechanism is depression of genes which code for hormones. Ectopic hormones are invariably peptides, and each is identical to some peptide product of an endocrine gland. However, the majority of ectopic hormones occur as biologically inactive precursors or subunits and therefore remain occult unless they are ...
متن کاملHormone producing tumors of the lung.
With the report of the production of ACTH by non-endocrine neoplastic tissue, Meador and associates set the stage for increasing clinical awareness of ectopic hormone production from a variety of neoplasms, bronchial adenomas and oat cell carcinoma of the lung in particular. The clinical syndromes are those expected from excess secretion of ACTH, ADH, parathyroid hormone, growth hormone, insuli...
متن کاملThymic neuroendocrine carcinoma producing ectopic adrenocorticotropic hormone and Cushing's syndrome.
Neuroendocrine carcinoma of the thymus, previously termed thymic carcinoid, is a rare clinical entity. Rarer still are such cases presenting with endocrinopathies. We report a case of thymic neuroendocrine carcinoma presenting with ectopic adrenocorticotroic hormone production and resultant Cushing's syndrome.
متن کاملThe ectopic adrenocorticotropic hormone syndrome in carcinoid tumors.
Ectopic production of adrenocorticotropic hormone by carcinoid tumors is relatively uncommon and may not be recognized by physicians. This report describes a woman who had Cushing syndrome from the ectopic secretion of adrenocorticotropic hormone by a carcinoid tumor. Her cause of death was a pneumonia that may have been secondary to her untreated hypercortisolism. There are threeinstructive el...
متن کاملEctopic expression of follicle-stimulating hormone receptors in thyroid tumors
INTRODUCTION In normal conditions follicle-stimulating hormone receptors (FSHR) are expressed in the ovary and the testis. They can also be expressed in gonadal tumors. However, recently we have found FSHR immunostaining in pituitary adenomas, adrenal tumors and neuroendocrine tumors (carcinoids). The aim of this study was to determine whether the same occurs in thyroid tumors. MATERIAL AND M...
